AB  - Standard sunflower oil contains predominantly alpha-tocopherol (>95%). The discovery by Demurin (1993) that within the sunflower collection there are examples of spontaneous mutations when it comes to tocopherols has made it possible manipulate tocopherol types and contents in the sunflower oil. Used in the study were genetic materials obtained by crossing the standard line HA-26-B with isogenic line BK-66-TPH-2-OL-1. After inbreeding F1, F2, F3 and F4, the F4 population was selected and grown in the greenhouse of the Institute of Field and Vegetable Crops in Novi Sad, Serbia. During the flowering, each individual plant was isolated with a natron bag in order to enable self-fertilization. The qualitative and quantitative tocopherol contents were determined by the HPLC method developed at our laboratory, according to the offi cial ISO 9936 method, on the Sykam HPLC system coupled with the both, UV and fluorescent detectors, and supported by the Clarity Chromatography Data Station (CDS) software for data acquisition and processing. Separation of tocopherols in the oil was carried out by the use of normal-phase chromatography procedure with the binary eluent n-hexane : ethyl acetate in proportion 75 : 25, and flow of the eluent through the chromatographic column at 1 ml/min.

AB  - The development of sunflower hybrids with high genetic potential for seed and oil yields requires information on the general combining ability (GCA) and specific combining ability (SCA) for plant height and head diameter in the F-1 generation. Used in this study were thirteen new divergent cms inbred lines (A), three Rf restorers utilized as testers, and their F-1 hybrids. The inbred A-lines, Rf-testers and F-1 hybrids differed significantly in the mean values for plant height and head diameter. The mode of inheritance for plant height was superdominance of the better parent and for head diameter it was dominance and superdominance of the better parent. Highly significant positive values of GCA for both traits were found in cms inbred line NS-G-7 and restorer line RHA-N-49. Based on the GCA values chosen were lines with the best GCA for plant height (NS-G-9, NS-G-7) originating from PRA-RUN and head diameter (NS-G-13, NS-G-12) originating from DES. The greatest highly significant positive SCA value was found in NS-G-1xRHA-N-49 for plant height and in NS-G-8xRUS-RF-OL-168 for head diameter. Non-additive genetic variance played the main role in the inheritance of both traits as confirmed by the GCA/SCA ratios in the F-1 generation, which were invariably smaller than unit. The female A lines had the highest contribution to the expression of head diameter and plant height.

AB  - Broomrape in sunflower fields in Serbia has been appearing with a varying intensity almost every year. Yield losses depend on the intensity of the attack and they can range from 5 to 100 %. According to previous investigations of the broomrape population in Serbia, race E is dominant. In 2011 in several regions in Vojvodina (North part of Serbia) broomrape appearance on some sunflower hybrids which have resistance to races A-E was noticed. This phenomenon indicates the possibility of changes in the broomrape population in our country. 
o	In order to determine changes in races, broomrape seeds were collected from the points (fields) where the attack in hybrids resistant to races A-E was noticed. Seed samples were kept in at the fridge on +4°C due to break dormancy. The reaction of some differential lines to the collected broomrape population was investigated in the greenhouse. Seed of differential lines was sown in plastic tubes in a mixture of sand and perlite. Before sowing sunflower seeds, broomrape seeds were put in tubes together with roots of susceptible sunflower genotype. The susceptibility or resistance of these lines to the collected broomrape population was evaluated on the presence of tubercles on sunflower roots. 
The presence of broomrape on hybrids resistant to race E was noticed primarily at points where for many years the sunflower hybrids resistance to races A-E has been tested. In those experimental fields sunflower has been cultivated every second year and that frequency of cultivation leads to inoculum increasing and higher selection pressure of broomrape to cultivated plant. Results obtained from the experiments in the green-house also indicate that there are some changes in broomrape population.
o	It should be pointed out that on resistant hybrids,the intensity of broomrape attack was low and could not significantly influence the yield. On the other hand in scientific and professional meaning, this is very important because the first appearance of broomrape plants with changed racial composition could be possibly an introduction to new period of its expansion and increasing of damages caused by this parasitic plant. These findings and observations are very important because of high practical importance of this parasitic plant and the fact that grown hybrids have low resistance level to new races. Another question is opened: Is this possibly new broomrape race present in Serbia identical to the new races present in Romania, Turkey or Spain or in some other regions in the world where this parasitic plant exists? The main problem is that other races except A-E are not determined strictly. The next step is the establishment of differential lines for separation of races 6, 7 etc., and on that way the results of scientist from different countries could be comparable.

AB  - Sunflower is a plant species with a prominent period of seed dormancy. Physiological maturation period can be accelerated under laboratory conditions using methods for breaking seed dormancy such as: previous cooling at 5-10°C, previous heating at 30-35°C, gibberellic acid treatment, KNO3, ethrel, etc. The aim of this study was to determine the duration of seed dormancy period of different sunflower hybrids and parent lines produced in Serbia, and to determine which of the methods for breaking seed dormancy gives the best results. Studies were carried out on five commercial sunflower hybrids and their parental components. Seed germination was determined after harvesting using standard laboratory methods and tetrazolium tests. The following methods were used for seed dormancy breaking: low temperature treatment of 5-10°C, high temperature treatment of 30-35°C, and treatment with gibberellic acid. The tests were performed in the period of 30, 50, and 90 days after harvesting. The application of gibberellic acid method gave the lowest values of seed germination, while statistical significant differences between the control and method of low and high temperatures were not found. Sunflower hybrids Sremac, Duško, NS-H-111, Velja and Branko, as well as the female lines of hybrid NS-H-111, and male lines of hybrids Sremac and Velja had no prominent seed dormancy 30 days after harvesting. Seed dormancy in female lines of hybrids Sremac, Duško, Velja and Branko and male lines of hybrids Duško, NS-H-111 and Branko was decreased 90 days after storage, but it was not completely removed.

AB  - Used in this study were 13 new divergent cms inbred lines (A) originating from four interspecies populations originating from three annual (H. debilis, H. praecox runyoni, H. deserticola) and one perennial (A. resinosus) wild species, three Rf restorer lines with good GCA were utilized as testers, and 39 F, hybrids were developed at the Institute of Field and Vegetable Crops in Novi Sad. A two-year trial with three replicates was set up on the Rimski Sančevi experiment field at the Institute of Field and Vegetable Crops using the line x tester method. Significant differences were found between the A lines, Rf testers and their F; hybrids for plant height (PH), head diameter (HD), total seed number per head (TSN), seed yield per plant (SY). The mode of inheritance for PH, TSN and SY was superdominance of the better parent, for HD it was dominance and superdominance of the better parent. Analysis of variance of the combining abilities revealed highly significant differences for GCA and SCA. Highly significant positive values of GCA for all traits were found in cms inbred line NS-G-4 and restorer line RHA-N-49. Based on GCA value, for lines were chosen with the best GCA for SY per plant (NS-G-7) and PH (NS-G-9) originating from interspecies populations, originating from H. praecox rynioni, HD (NS-G-12), TSN per head (NS-G-11) lines originating from interspecies populations, originating from H. deserticola.

AB  - The susceptibility of 10 experimental sunflower hybrids to the causal agent of white rot (S. sclerotiorum) and broomrape (O. cumana) was tested at two localities (Bečej and Svetozar Miletić) in naturally highly infested fields in 2009. There are significant differences between hybrid susceptibility to white rot and broomrape. The basal stalk rot was absolute dominant type of disease and was evident on 16.7 % of plants in Bečej. In Svetozar Miletić fungus attack did not noticed in any tested hybrid. Broomrape attack was noticed on six tested hybrids at both localities. It can be observed that hybrids in Bečej had significantly higher yields compared to those achieved in Svetozar Miletić. Genetic capacity of the hybrids and favorable conditions for sunflower growth had the most important influence of achieved seed yield. Negative influence of white rot attack on seed yield was lower because it appeared in root and stalk form. Although on certain plants broomrape attack was of high intensity generally it was not so sever and therefore harmfulness of this parasitic plant could not manifest significant influence on seed yield

abstract = "The susceptibility of 10 experimental sunflower hybrids to the causal agent of white rot (S. sclerotiorum) and broomrape (O. cumana) was tested at two localities (Bečej and Svetozar Miletić) in naturally highly infested fields in 2009. There are significant differences between hybrid susceptibility to white rot and broomrape. The basal stalk rot was absolute dominant type of disease and was evident on 16.7 % of plants in Bečej. In Svetozar Miletić fungus attack did not noticed in any tested hybrid. Broomrape attack was noticed on six tested hybrids at both localities. It can be observed that hybrids in Bečej had significantly higher yields compared to those achieved in Svetozar Miletić. Genetic capacity of the hybrids and favorable conditions for sunflower growth had the most important influence of achieved seed yield. Negative influence of white rot attack on seed yield was lower because it appeared in root and stalk form. Although on certain plants broomrape attack was of high intensity generally it was not so sever and therefore harmfulness of this parasitic plant could not manifest significant influence on seed yield",

AB  - The creation of new sunflower hybrids with high genetic potential for seed yield on the basis of interspecies hybridization requires a possession of the information about the mode of inheritance and the combining abilities of the created inbreed lines for the total seed number per head and the mass of 100 seeds. Apart from this the research of interdependence between yield components and seed yield allows the defining of traits which have the biggest influence on the yield formation. Significant differences were found among the A lines, Rf testers and their F1 hybrids in total seed number per head and the mass of 100 seeds. Analysis of variance of the combining abilities revealed highly significant differences for GCA and SCA. Highly significant positive value GCA was demonstrated by A-line NS-GS-5 for both traits. Hybrid NS-GS-5xRHA-R- PL-2/1 has the highest significant value SCA for both traits. The main role in inheritance of the total seed number per head and the mass of 100 seeds is played by non additive component of the genetic variance which is confirmed by the GCA/SCA relation in F1 generation that is less than one (0.11, 0.24). Rf-testers had the highest average contribution in the expression of the total seed number per head (55.8%) while for the mass of 100 seeds a more significant contribution was given by A-line (70.6%). A strong positive interdependence has been determined between seed yield and total seed number per head (0.376*) and a very strong positive interdependence was determined between seed yield and the mass of 100 seeds (0.823). These research can be significant for the creation of new high-yielding sunflower hybrids on the basis of interspecies hybridization.

AB  - Four interspecies populations, originating from three annual (H. debilis, H. praecox, H. deserticola) and one perennial (H. resinosus) wild species, were used to produce 13 new (cms) inbred lines with cytoplasmic male sterility, three Rf restorer lines with good general combining ability used as testers and their F1 hybrids. A two-year trial with three replicates was set up using the line × tester method. The inbred A-lines, Rf-testers and F1 hybrids differed significantly in the mean values for both studied traits. The mode of inheritance for leaf area was dominance and superdominance of the better parent and for plant height it was superdominance of the better parent. Highly significant positive values of general combining ability for both traits were found in inbred lines NS-G-7, NS-G-8, NS-G-9. The greatest highly significant positive specific combining ability value was found in NS-G-6 × RUS-Rf-OL-168 for the total leaf area per plant and in NS-G-6 × RHA-N-49 for plant height. The non-additive gene effect had greater influence on both traits. A significant heterotic effect was found for both traits in relation to the parental average so as in relation to the better parent.

AB  - Discovery of tribenuron-methyl resistant wild Helianthus annuus L. population (ANN-KAN) created an opportunity for expansion of sunflower herbicide resistance breeding program. The aim of this study was development of sunflower hybrids resistant to tribenuron-methyl. Creation of tribenuron-methyl resistant hybrids would enable the use of a wider palette of herbicides for sunflower, more efficient chemical control of Cirsium arvense and more economically profitable post-emergence control of some annual broad-leaves weeds in sunflower. Original populations SURES-1 and SURES-2 are homozygous for resistance to tribenuron-methyl. F1 generations produced from the crossings are completely resistant to tribenuron-methyl, pointing out to dominant way of inheritance of this trait. Studies on the exact number of genes controlling the resistance are in progress. Tribenuron-methyl resistance was transferred from original populations into a number of female and male inbred lines of cultivated sunflower. These inbred lines could enable creation of a number of hybrids resistant to tribenuron-methyl. Hybrids SUMO-1-PR, SUMO-2- OR and SUMO-3 are resistant to doubled application dose of tribenuron-methyl. Agronomical characteristics of these hybrids are on the level with the leading conventional sunflower hybrids.

AB  - For much of the past century, mutagenesis has gained popularity in plant genetics research as a means of inducing novel genetic variation. Induced mutations have been applied for the past 40 years to produce mutant cultivars in sunflower by changing plant characteristics that significantly increase plant yield and quality. The present study is focused on generating baseline data to elucidate the role of genotypic differences in the response of sunflower to induced mutagenesis with the aim of expanding the applicability of the use of induced mutant stocks in the genetic improvement of the crop and in its functional genomics. The strategy adopted was to estimate the optimal treatment conditions (doses of mutagens) through relating the extent of damage in seedling progeny to the exposure levels of the initiating propagates to mutagens. Seeds of fifteen elite sunflower genotypes of commonly used as breeding stocks and grown on commercial scales were treated with a range of mutagens: gamma rays (γ rays); fast neutrons and with ethyl-methane-sulphonate (EMS) at different treatment doses. The three mutagenic agents affected seedling height, reducing it with increasing dosage. Based on the mutagen damage on seedling height, the 50% and 30% damage indices (D50 and D30, respectively) were estimated for the 15 sunflower genotypes for the three mutagens. The D50 (D30) values for the sunflower lines ranged from 120 to 325 Gy (5 to 207 Gy) for gamma irradiation; 9 to 21 Gy (0.1 to 10 Gy) for fast neutrons and 0.69 to 1.55% (0.01 to 0.68%) concentration of EMS.

AB  - Imidazolinone herbicides are one of the most feasible methods for broomrape control, especially in intensive agriculture. In this, trial we evaluated the resistance of seven different sunflower genotypes of F1 and F2 generation and five commercial hybrids to imidazolinone herbicides and also their effect on broomrape control. The experiment was conducted in field conditions in Svetozar Miletić locality (North
Serbia), a naturally highly infested plot. Race E was determined in this region ten years ago for the first time in Serbia. The analysis of the population, which was done by a set of differential lines, showed that broomrape in that locality still belong to race E of the parasite. Sunflower was treated with imidazolinone herbicide (Pulsar-40) with 1.2 l/ha (at a concentration rate 0.25%) at three-leaf stage. Controls were the same non-treated genotypes and commercial hybrid NS-H111 which is susceptible to broomrape and IMI herbicides. Evaluation of herbicide effect was done 14
days after application when sunflower plants were at the beginning of the budding stage. The reaction of sunflower genotypes to applied herbicide was evaluated according to the reaction of plants. The phytotoxicity of herbicide was expressed by the following symptoms: total plant deterioration, severe chlorosis and slightly yellowing. Intensity of phytotoxicity varied depending on the observed genotype.Percentage of dead plants ranged from 13-68%, plants with severe chlorosis and curly leaves ranged from 0-35% and symptoms of slightly chlorosis were observed on up to 20% percentages of evaluated plants. Plants which expressed susceptibility to applied herbicide such as chlorosis and yellowing totally recovered during the time but the phytotoxicity had influence on the yield and quality of seeds. Seed yield of plants with symptoms has been decreased from 43,7 to 90,1% related to control. Although we obtained good results in broomrape control in sunflower by one application of IMI-herbicide, we recommend two split applications of IMI herbicides.

AB  - Broomrape (Orobanche cumana Wallr.) presents a serious problem in sunflower production in a number of countries. The population of broomrape has been stable in Serbia for a long period of time, but the racial composition has changed in recent years, with race E being predominant in the regions of north Bačka and Banat. Cultivated sunflower is genetically narrow and deficient in many desirable genes. Sources of resistance genes to broomrape can be found in a number of wild sunflower species. New 7 Rf inbred lines (RHA-D- 1, RHA-D-2, RHA-D-5, RHA-D-6, RHA-D-7, RHA-D-8, RHA-D-9) were produced from interspecies population originating from H. deserticola (DES-1474-1) in IFVC. The inbreeding of the selected plants from interspecific populations started in 1995 (S1). The first screening of sunflower Rf lines for broomrape resistance was done in a glasshouse in 1999 (S5). The seed from the resistant plants was tested in infested fields, in the area of S. Miletić and B. Topola during 2000 (S6). Selection of resistant plants was checked from 2001 (S7) to 2003 (S9). The same procedure was conducted in Pačir from 2004 (S10) to 2008 (S14) and in the area of Lipar in 2009 (S15). Experimental hybrids were produced by crossing new Rf lines developed from interspecific population (DES-1474-1) resistant to broomrape race E with cms female lines susceptible to broomrape. The resistance of new 28 experimental hybrids to broomrape was checked on locations in Serbia (Pačir 2006, 2007, 2008) and at the location (Lipar 2009) with three controls: hybrid Bačvanin, resistant to race E, hybrid NS-H-111 resistant to race A, B, C, D, susceptible to E race and line AD- 66 susceptible to all broomrape races. The resistance of the same hybrids was also tested at a location in Romania (Baragan, Braila) in 2008. All examined hybrids were resistant to broomrape race E on all locations.

AB  - Path coefficient analysis was used to separate direct and indirect effects of studied traits on seed oil content and seed yield, and to identify traits that could be used as selection criteria in sunflower breeding. Significant and highly significant correlations were found between most of the examined traits. Highly significant negative correlations have been established between stem diameter, total leaf area per plant, head diameter and 1,000-seed weight on one side and seed oil content on the other. Highly significant positive correlations have been established between seed yield on one side and stem diameter, total leaf area per plant, head diameter, total number of seeds per head, and the 1,000-seed weight on the other. The weight of 1,000 seeds had a highly significant direct negative effect on seed oil content and a highly significant direct positive effect on seed yield. The total number of seeds per head has demonstrated a highly significant direct positive effect on seed yield and oil content. The total leaf number per plant has demonstrated a significant direct positive effect on seed yield. A path coefficient analysis of seed yield at phenotypic level indicated that maximum direct effects were shown by the weight of 1,000 seeds, total number of seeds per head and total leaf number per plant. The total number of seeds per head was the most important trait that determined seed yield and oil content. The obtained results can be used in sunflower breeding programs aimed at the development of sunflower hybrids that combine high genetic potentials for seed yield and seed oil content.

These hybrids were produced by crossing female inbred lines (Ha-26PR-A, PH-BC2-92-A and Ha-98-A) susceptible to broomrape race E and new Rf inbred lines (RHA-D-2, RHA-D-5, RHA-D- 6, RHA-D-7, RHA-D-8), developed from interspecific populations originating from H. deserticola and resistant to race E. All examined hybrids were resistant to broomrape in both locations. Since broomrape race F is present in the location in Romania, it is expected that the new Rf inbred lines - male components of the examined hybrids, possess the resistance gene for race F also.

AB  - An experiment was conducted at Rimski Šančevi Experiment Field of Institute of Field and Vegetable Crops in Novi Sad during 2000 - 2005. The soil in the experimental plot was calcareous chernozem on loess terrace. Using the yield response factor (ky), the study investigated how sunflower yield and evapotranspiration were affected by deficit of available soil water during the growing season. The experiment consisted of an irrigated treatment (T1), in which irrigation was used when soil moisture levels dropped to 60-65% of FC (field capacity), and a nonirrigated control treatment (T0). The sunflower hybrid used in the study was NS-H-111. On average, no significant differences in yield level were observed between T1 (3.79 t ha-1) and T0 (3.75 t ha-1) treatments. Seasonal evapotranspiration (ETm) obtained in T1 treatment was in the 402-479 mm range. The yield response factor (ky) was obtained as 0.20 for total growing season and 0.27, 0.31 and 0.48 for vegetative, flowering and yield formation period, respectively. Period from flowering to maturity was the most sensitive towards water deficiency.

The population of broomrape has been stable in Serbia for a longer period of time, but the racial composition has changed in recent years, with race E being predominant in the regions of north Backa and Banat. Cultivated sunflower is genetically narrow and deficient in many desirable genes. Its genetic variability can be increased by the use of wild sunflower species and interspecific hybridization.
The resistance of 15 new experimental hybrids to broomrape was tested on locations in Serbia (Pačir) during three years (2006, 2007, 2008) and in Romania (Baraganu, Bralia) during 2008. These hybrids were produced by crossing female inbred lines (Ha-26PR-A, PH-BC2-92-A and Ha-98-A) susceptible to broomrape and new Rf inbred lines (RHA-D-2, RHA-D-5, RHA-D-6, RHA-D-7, RHA-D-8), developed from interspecies population originating from H. deserticola, and resistant to broomrape race E. All examined hybrids were resistant to broomrape on both locations. Since broomrape race F is present on location in Romania, it is expected that the new Rf inbred lines-male components of examined hybrids, have the resistance gene for race F also.

AB  - The development of sunflower hybrids with high genetic potentials for seed and oil yields requires
information on the GCA and SCA for agronomically important traits in the F1 generation. In this study were used seven new divergent cms inbred lines (A) lines, three Rf restorers utilized as testers, and 21 F1 hybrids developed at the Institute of Field and Vegetable Crops in Novi Sad. Significant differences were found between the A lines, Rf testers and their F1 hybrids for petiole length (PL), total leaf number per plant (TLN), total leaf area per plant (TLA), seed yield per plant (SY), seed oil content (OC), and oil yield per plant (OY). Analysis of variance of the combining abilities revealed highly significant differences for GCA and SCA. The nonadditive component of genetic variance (dominance and epistasis) contributed more to total genetic variance, as evidenced by the GCA/SCA ratio in the F1 generation being below the value of one for all the traits studied. The greatest average contribution to the expression of all of the traits was found in the female A lines, while the contributions of the Rf testers and line x tester interaction were less significant. Evaluation of the combining abilities of the line NS-GS-5 suggests that this line could justifiably be used as a parent in breeding programs for increasing sunflower seed and oil yields.
Analysis of SCA for OY per plant identified the following hybrids as promising: NS-GS-5xRHA-R-PL- 2/1, NS-GS-6xRHA-N-49, NS-GS-2xRHA-N-49, NS-GS-1xRUS-RF-OL-168.

AB  - The objective of this study was to determine the relationship between SSR based genetic distance (GD) of new NS sunflower inbred lines for most important agronomic traits and heterosis. Twenty three sunflower inbred lines (twenty restorer lines and three female lines used as testers) were selected based on their diverse genetic background for plant height, head diameter, thousand seed mass, oil content, seed yield per plant and oil yield per plant. Significant heterosis was observed in hybrid combinations for all examined traits except oil content. Genetic distance between pairs of tested sunflower inbred lines ranged from 0.13 to 0.8. There was no significant positive correlation between genetic distance and mid- and better-parent heterosis, specific combining ability and mean value in any of the examined traits for all 60 hybrids. A highly significant negative correlation was found between GD and mean oil percentage (r=-0.33 p<0.01). However significant correlations between GD and better-parent heterosis for thousand seed weight were found for hybrids of the tester line HA-19 (r=0.43 p<0.05) and between GD and mid-parent heterosis for plant height for hybrids of the tester line HA-26 (r=0.47 p<0.05). Although GD was generally a poor predictor of heterosis, better results are obtained if hybrid combinations for each tester and each trait are analyzed separately.

AB  - The sunflower is one of the four most important oilseed crops in the world, and the nutritional quality of its edible oil ranks among the best vegetable oils in cultivation. Typically up to 90% of the fatty acids in conventional sunflower oil are unsaturated, namely oleic (C 18:1, 16%-19%) and linoleic (C 18:2, 68%-72%) fatty acids. Palmitic (C 16:0, 6%), stearic (C 18:0, 5%), and minor amounts of myristic (C 14:0), myristoleic (C 14:1), palmitoleic (C 16:1), arachidic (C 20:0), behenic (C 22:0), and other fatty acids account for the remaining 10%. Advances in modem genetics, most importantly induced mutations, have altered the fatty acid composition of sunflower oil to a significant extent. Treating sunflower seeds with gamma- and X-rays has produced mutants with 25%-30% palmitic acid. Sunflower seed treatment with X-rays has also resulted in mutants having 30% palmitoleic acid, while treatments with mutagenic sodium azide have produced seeds containing 35% stearic acid. The most important mutations have been obtained by treatment with dimethyl sulfate, which produced genotypes with more than 90% oleic acid. Mutants have also been obtained that have a high linoleic acid content ( gt 80%) by treating seeds with X-rays and ethyl methanesulfonate. Of the vitamin E family of compounds, sunflower oil is known to predominantly contain a-tocopherol ( gt 90%). Spontaneous mutations controlled by recessive genes have been discovered that significantly alter tocopherol forms and levels. The genes in question are tph(1) (50% alpha- and 50% P-tocopherol), tph(2) (0%-5% alpha- and 95%-100% gamma-tocopherol), and tph(1)tph(2) (8%-40% alpha-, 0%-25%beta-, 25%-84% gamma-, and 8%-50% delta-tocopherol). The existence of (mutant) genes for increased levels of individual fatty acids and for different forms and levels of tocopherol enables the development of sunflower hybrids with different oil quality. The greatest progress has been made in developing high-oleic hybrids (>90% oleic acid). There has been considerable work done recently on the development of high-oleic hybrids with altered tocopherol levels, the oil of which will have 10-20 times greater oxidative stability than that of conventional sunflower oil. While sunflower breeders work on developing hybrids with altered oil quality, medical scientists in general and nutritionists in particular will determine the parameters for the use of these novel types of oil that can improve human nutrition and be used in the prevention of cardiovascular diseases.

AB  - One of the primary tasks of sunflower breeding is the development of inbred lines by interspecific hybridization for the purpose of obtaining high-yielding, stable hybrids that are characterized by altered plant appearance and the ability to produce a higher number of plants per unit area under intensive agriculture conditions. Studied in this paper by the line x tester method were seven new divergent cms inbred lines (A) lines, three Rf restorers utilized as testers, and 21 F1 hybrids developed. Significant differences in the mean values of all the traits studied were observed. Highly significant GCA and SCA values were obtained for petiole length (PL) and total leaf area per plant (TLA). The nonadditive component of genetic variance played the main role in the inheritance of both these traits. This was confirmed by the GCA/SCA ratios for PL and LA in the F1 generation, which were below the value of one (0.43 and 0.07, respectively). The greatest average contribution to the expression of PL (49.9%) and TLA (57.1%) was found in the female A lines. A positive correlation was found between seed yield (SY) and PL (0.374*) and TLA (0.630**), while seed oil content (SOC) and TLA were found to be negatively correlated (-0.520**). The findings of this study can be used in the development of new high-yielding sunflower hybrids with high yields based on interspecific hybridization.

Ustanovljena je pozitivna međuzavisnost prinosa semena (PS) sa DLD (0.374*) i ULP (0.630**). Između sadržaja ulja u semenu (SU) i ULP ustanovljena je značajna negativna međuzavisnost (-0.520**). Ova istraživanja mogu biti od značaja za stvaranje novih visoko prinosnih genotipova suncokreta na bazi interspecies hibridizacije.",

AB  - NS sunflower hybrids are developed primarily for the Serbian agro-ecological conditions while taking into account the limiting factors of the domestic sunflower production.The 2006 sunflower yields were negatively affected by excessive soil moisture, high groundwater levels, and floods occurring during the optimum period for sowing in nearly all sunflower-growing regions of the country. The increased moisture hampered planting and increased weediness thus negatively affecting the yields. Weather conditions in the latter part of the vegetation period had a favorable effect on sunflower growth and development. Seed and oil yields obtained in a network of small-plot trials varied according to location and cultural practices used. In both of the sunflower regions studied in the paper, the highest seed yields were produced by the hybrids Sremac, NS-H-111 and NS-H-45. The highest oil yields in the trial network were obtained with the hybrids Baca, Pobednik, Olivko and Sumadinac. The hybrids Baca, NS-H-111 and Sremac produced the highest oil yields in the province of Vojvodina, while the hybridsSumadinac, HS-H-111 and Stig did the same in central Serbia. In a two-year study in Vojvodina, the new hybrids Sremac, Sumadinac and Somborac proved their worth by producing higher seed yields than the hybrids commonly used in commercial production. Results of the small-plot trials confirmed the commercial value of the standard hybrids and showed the value of the new ones, which are expected to become the mainstays of sunflower production in the country as they gradually replace the currently predominant hybrids.

AB  - The cultivated sunflower (Helianthus annuus L.) is one of most important oil crops of the world. Although sunflower is primarily grown for extraction of its seed oil there is a limited production of non-oilseed sunflower types which are used in confections industry or as bird feed. The objective of this research was development of hybrids with high and stable oleic acid content and modified tocopherol composition, with high values for the two most important agronomic characters (seed yield and oil yield) and high tolerance to Phomopsis. The incorporation of the gene Ol+tph1 into these genotypes has led to the development of high-oleic hybrids with altered tocopherol profiles. Oil of these hybrids has a much longer shelf-life than standard sunflower oil. The process of incorporating the genes Ol+tph2 and Ol+tph1tph2 into highly productive sunflower genotypes is under way. The most important results of this line of research are the newly developed female lines with the oleic acid content in oil over 90% and the male lines (restorers) with an oleic acid content in the 89-93% range. Using these lines, hybrids will be developed whose oleic acid content in oil will exceed 90%.

AB  - Significant manifestation of heterosis for agronomically important traits is the main precondition for obtaining productive sunflower hybrids (Škorić et al., 2006). Development of high-yielding and stable sunflower hybrids based on interspecific hybridization requires knowledge of heterotic effects occurring in the F1 generation. Heterosis for seed yield per plant, total seed number per head and 1,000-seed weight was studied in interspecific hybrids obtained by the line × tester method. The seven female inbred lines used in the study had been developed by interspecific hybridization, while the three male restorer inbreds with good combining abilities were used as testers in the form of fertility restorers. Twenty-one F1 hybrids were obtained by crossing each tester with each female inbred line. A trial with the lines and F1 hybrids was set up at Rim-ski Šančevi. Experiment Field of Institute of Field and Vegetable Crops in Novi Sad using a randomized block design with three replications. Our study found significant differences in the mean values of all the traits under investigation. Heterosis values for seed yield were positive and highly significant relative to parental average (98.4-274.1%) as well as better parent (55.8-223.2%). Considerably less heterosis was found for total seed number per head (69.6-203.7%) relative to parental average and better parent (47.6-183.3%). With 1,000-seed mass, the values ranged between 26.5% and 48.8% relative to parental average and from -42.4% to 30.9% relative to better parent. This study could prove useful in the development of new high-yielding sunflower hybrids based on interspecific hybridization.

AB  - Study of inbreeding and heterosis in sunflower has been taking place for over 80 years now. Practical application of the phenomenon of heterosis in this species began after the discovery of a suitable source of cytoplasmic male sterility in 1969 and that of restorer genes. Many authors have reported significant manifestation of heterosis for seed yield and yield components as well. Also, the mode of inheritance of agronomically important traits in the F1 and F2 generations has been thoroughly examined. Positive correlations for yield have been established between parental lines and F1 hybrids. The GCA and SCA for yield and yield components have been well studied. Solutions have been suggested on how to increase the harvest index and sink capacity as well as the contributions of individual physiological parameters in the process of yield augmentation. In order to increase heterotic effects for seed yield and oil yield and direct and indirect yield components, it is necessary to increase the genetic variability of pre-breeding materials, achieve improved efficacy at the inbreeding stage, and streamline and accelerate the process of GCA and SCA evaluation using molecular markers and other biotechnology methods in order to achieve breeding goals. Seed oil content should be increased to over 55% using recurrent selection methods. Special focus in breeding programs should be placed on the development of high-oleic hybrids (>95%) with a high genetic potential for oil yield, resistance to the dominant diseases, and wide environmental adaptability that would be used for industrial purposes (production of biodiesel, or hydrogen). In order to extent the duration of sunflower oil stability, beta, gamma and delta tocopherols should be incorporated instead of alpha ones alongside the Ol genes. The exiting genetic variability of the cultivated sunflower makes it possible to develop hybrids with a genetic potential for seed yield of over 6 t/ha and seed oil content of over 55%. Most often, however, sunflower yields obtained in large-scale commercial sunflower production are in the 1.5-3.0 t/ha range. There are multiple limiting factors preventing the realization of the high genetic potential of this crop. Their removal will enable commercial sunflower yield to stabilize at levels of 4 t/ha and above. Diseases are the main limiting factor affecting sunflower production in all sunflower-growing parts of the world. Development of exotic germplasm through further use of wild sunflower species, distant hybridization and genetic transformations should be used to provide genes for resistance to all dominant pathogens and broomrape. Efficient breeding methods should be employed to increase sunflower tolerance of air and soil drought and salinity and to attain wider resistance to herbicides.

AB  - The inheritance of the reaction of sunflower to downy mildew was investigated using resistant and susceptible near isogenic lines (NILs) and their F-3 families. Resistance to race 730 was evaluated using the whole seedling inoculation technique. Seventy-three F-3 families were inoculated, among which 54 families were resistant and 19 susceptible, fitting a 3 : 1 segregation ratio. F-3 families were also studied using several PCR markers. Ten markers at the Pl6 locus, specific for the resistant line, also segregated in F-3 families with a 3 : 1 ratio. The same segregation ratio occurred for microsatellite haplotypes that resembled the resistant parent, and were amplified with ORS 166 and ORS 1043. The only common fragment that was observed between resistant and susceptible parental lines was one of the TIR-NBS-LRR resistance gene analogue markers, having a restriction site. Two co-dominant cleaved amplified polymorphic sequence (CAPS) markers were obtained. The mapping data indicate that several dominant markers and two CAPS markers, developed here, completely co-segregate with the Pl6 gene conferring resistance to race 730. CAPS markers will facilitate efficient marker-assisted selection for sunflower resistance to downy mildew race 730.

abstract = "The inheritance of the reaction of sunflower to downy mildew was investigated using resistant and susceptible near isogenic lines (NILs) and their F-3 families. Resistance to race 730 was evaluated using the whole seedling inoculation technique. Seventy-three F-3 families were inoculated, among which 54 families were resistant and 19 susceptible, fitting a 3 : 1 segregation ratio. F-3 families were also studied using several PCR markers. Ten markers at the Pl6 locus, specific for the resistant line, also segregated in F-3 families with a 3 : 1 ratio. The same segregation ratio occurred for microsatellite haplotypes that resembled the resistant parent, and were amplified with ORS 166 and ORS 1043. The only common fragment that was observed between resistant and susceptible parental lines was one of the TIR-NBS-LRR resistance gene analogue markers, having a restriction site. Two co-dominant cleaved amplified polymorphic sequence (CAPS) markers were obtained. The mapping data indicate that several dominant markers and two CAPS markers, developed here, completely co-segregate with the Pl6 gene conferring resistance to race 730. CAPS markers will facilitate efficient marker-assisted selection for sunflower resistance to downy mildew race 730.",
