AB  - S obzirom na postojanje interakcije između genotipa i spoljašnje sredine, ispitivanje performansi prinosa zrna novostvorenih genotipova kukuruza vrši se na nekoliko lokacija i/ili godina u ogledima sa manjim oglednim parcelama (MESPT).

AB  - Considering the existence of genotype × environment interaction, grain yield performance testing of newly created maize genotypes is performed in several locations and/or years in trials with smaller experimental plots (MESPT). This should ensure the selection of the best genotypes, which is of critical importance for the breeding process. Certainly, the level of grain yield and yield stability are the most important features when it comes to breeding corn within the framework of the appropriate maturation groups. It is important to choose the locations where the experiments will be carried out, with the aim of covering the range of soil and climatic conditions of the target cultivation area. As it is about conducting experiments where neither soil nor climatic factors can be controlled, and due to a number of other circumstances, the data we get in these experiments are not always perfect.

AB  - Early maturity is a highly important factor in the interrelations between yield, grain moisture, and plant density, contributing to cost-efficient maize production. Landraces conserved in gene banks present a promising basis for enriching the diversity of early maize breeding material. To start and speed up the mobilization of the maize genetic resources maintained in the ex situ Maize Research Institute Zemun Polje gene bank collection, which are currently scattered, little studied, and underused, 63 landraces were selected as new potential sources of early maturity; their test-cross performance with two divergent early testers was evaluated. The majority of the landraces with a prevailed flint type (29) exhibited heterosis for yield when crossed with the Iowa Stiff Stalk Synthetic—Iowa Dent tester (102NS), out of which 20 top crosses expressed grain moisture below the defined threshold value (21.1%). The best performing landraces can be used as a starting point for a new pre-breeding programme for the broadening of flint maize breeding material. In parallel, nine landraces expressed simultaneous heterosis when crossed with the flint tester (14NS), exhibiting grain moisture above the threshold value. A simultaneous heterotic effect with two divergent inbred testers implies the existence of an independent heterotic pool. These findings will contribute to the broadening of maize breeding material for early maturity and low grain moisture at harvest, which are important goals in maize breeding.

AB  - Significant amounts of crop diversity, especially in out-crossing species like maize (Zea mays L.) is, are often distributed both between and within related groups of accessions. Thus, a detailed characterization and classification of gene bank accessions should be performed prior to use of the best of them for introgression programs to enlarge the genetic base of the elite germplasm pool. Based on performances per se, 40 landraces were chosen out of the wide pool of Western Balkan landraces, previously clustered into 11 homogenous groups. The objective of this study was to evaluate the heterotic pattern of landraces in testcrossing with three divergent elite testers L217, L73B013 and L255/75-5. According to the results of a two-year trial conducted at four locations, landraces 1267, 1346, 197, 1569, 1509 and 2036 expressed the best general combining abilities (GCA) for grain yield. Landraces 1960, 642, 2006, 1945, 1346, 1569, 1450, 1534, 1509 and 1665 performed well in crosses to L217, while landraces 1960, 773, 1798, 1665, 632, 877 and 1569 gave the best results in crosses to inbred tester L73B013. In crosses to inbred tester L255/75-5, the highest heterotic effects were expressed by landraces 467, 773, 1346, 1534, 2249 and 288. Particular attention is to be paid to landraces 1346, 1569 and 1509, having simultaneously high GCA and specific combining abilities (SCA). A certain number of landraces expressed heterosis with two inbred testers, indicating existence of a new unrelated heterotic pattern within the local germplasm pool evaluated.

AB  - Field trials supposed to enable selection of the most successful genotypes which is critical because of the existence of Genotype by Environment interaction. To assess this interaction we are forced to conduct field trials in several environments and/or years. When we asses grain yield of maize hybrids during the breeding process, it is always based on multi-environment small plot field trial (MESPT). That is why this part of the breeding process is most demanding in terms of technical, financial and labor requirements. In this paper, one possible systematic approach to assessing multi-environment field trials conduction is described. The main goal of the described approach is to provide the best possible results with the use of reasonable resources. As the results of trials cannot be directly interpreted without previous statistical processing, quality of raw data as input for biometrical (statistical) analysis is essential for obtaining a relevant and objective measure of genotype relative value in terms of productivity and adaptability (reliability) of new advanced maize hybrids. There are many definitions of data quality but data is generally considered high quality if it is fit for intended uses in operations, decision making and planning. The main aim of this paper is to underline the importance of the data cleaning process in MESPT.
AB  - Svrha poljskih ogleda u oplemenjivanju biljaka je da omogući odabir najuspešnijeg genotipa, što nije uvek jednostavan zadatak prevashodno zbog postojanja interakcija genotipa i spoljašnje sredine. Upravo zbog postojanja interakcija sortni ogledi se izvode u brojnim lokacijama i godinama, kako bi se dobila pouzdana procena vrednosti genotipa. U toku oplemenjivačkog procesa, procena prinosa, recimo, hibrida kukuruza, je zasnovana isključivo na rezultatima višelokacijskih sortnih mikro ogleda (VSMO). Ovaj deo oplemenjivačkog procesa je stoga najzahtevniji sa tehničkog i finansijskog aspekta ali i sa stanovišta angažovanja obučene radne snage i specifične opreme. U ovom radu prikazan je jedan od mogućih sistematskih pristupa u proceni višelokacijskog sortnog ogleda. Glavni cilj predstavljenog pristupa je da obezbedi najbolji mogući rezultat uz angažovanje razumnih resursa. Kako rezultati poljskog ogleda ne mogu biti direktno interpretirani bez prethodne obrade podataka, kvalitet ulaznih-sirovih podataka je od krucijalne važnosti za dobijanje relevantnih i objektivnih procena relativne vrednosti novostvorenih genotipova (hibrida kukuruza) u smislu njihove produktivnosti i stabilnosti. Postoje brojne definicije kvaliteta podataka, ali se podaci generalno mogu smatrati visoko kvalitetnim ako su odgovarajući za planirane statističke obrade, donošenje odluka i planova. Cilj izloženog rada je da naglasi značaj pročišćavanja/čišćenja podataka pre procesa statističke obrade podataka sortnih mikro ogleda.

U toku oplemenjivačkog procesa, procena prinosa, recimo, hibrida kukuruza, je zasnovana isključivo na rezultatima višelokacijskih sortnih mikro ogleda (VSMO). Ovaj deo oplemenjivačkog procesa je stoga najzahtevniji sa tehničkog i finansijskog aspekta ali i sa stanovišta angažovanja obučene radne snage i specifične opreme. U ovom radu prikazan je jedan od mogućih sistematskih pristupa u proceni višelokacijskog sortnog ogleda. Glavni cilj predstavljenog pristupa je da obezbedi najbolji mogući rezultat uz angažovanje razumnih resursa. Kako rezultati poljskog ogleda ne mogu biti direktno interpretirani bez prethodne obrade podataka, kvalitet ulaznih-sirovih podataka je od krucijalne važnosti za dobijanje relevantnih i objektivnih procena relativne vrednosti novostvorenih genotipova (hibrida kukuruza) u smislu njihove produktivnosti i stabilnosti. Postoje brojne definicije kvaliteta podataka, ali se podaci generalno mogu smatrati visoko kvalitetnim ako su odgovarajući za planirane statističke obrade, donošenje odluka i planova. Cilj izloženog rada je da naglasi značaj pročišćavanja/čišćenja podataka pre procesa statističke obrade podataka sortnih mikro ogleda.",

AB  - During long-term storage of gene bank accessions, even under excellent conditions,
seed viability declines with period of storage, resulting in seed death. On the other
hand, regeneration of gene bank accessions should be done as rare as possible,
because, each time an accession is regenerated, there is a risk that the genetic
integrity of accession is compromised by genetic drift, selection, or gene flow.
Occasionally it happens that the sample's viability drops below the standard level,
when there is a risk that regeneration from such a sample disrupt the identity and
integrity of an originally collected sample. Different pre-sowing treatments are
often used to improve seed germination and early seedling growth in various crops.
The aim of this study was to evaluate the effect of three different seed priming
treatments on four maize gene bank accessions, stored for 5 and 30 years under
medium-term conditions (t=4-5°C; RH=45-50%). The standard seed germination
test on filter paper (BP, 20⇔30°C, ISTA Rules) and cold tests were performed.
The following parameters were observed: germination including germination
energy, seedlings fresh and dry weight, as well as seedlings length. Data analysis
showed that the treatments had a positive effect on the seedling’s fresh and dry
weight, but not on the seedling’s length. Also, seed priming treatments improved
germination dynamics.

AB  - In the process of plant breeding the application of relevant breeding criteria is very important. The Path analysis is broadly applied with the aim to define yield components that mostly determine the yield and that can be used as quality breeding criteria. However, the significance of revealed relationships between yield and yield components can be affected by various factors, such as diverse genetic material that is observed, traits included into analysis, environments in which the material is observed, as well as, the applied statistic approach to determine the nature of the relationships itself. The interrelationships of yield and yield components of 15 commercial maize hybrids were observed using the Path and factor analyses. According to results of Path analysis, plant height, ear diameter and grain moisture had highly significant genetic and phenotypic direct effects on grain yield. At the same time, factor analysis points out significant effects of two factors on grain yield. Factor 1 was mostly determined by ear length and number of kernels per row, while grain moisture content, ear and cob diameter mostly determined Factor 2.

AB  - Modern agriculture, breeding procedures, as well as competition among breeding institutions contribute to further reduction of already narrowed diversity of soybean commercial varieties. The objective of the study was to characterize eighteen soybean cultivars from three different breeding programs for agro-morphological traits and to reveal genetic diversity using molecular markers. Morphological description was performed with 13 qualitative and 9 quantitative traits. The genetic relationships were estimated using 21 RAPD markers. PIC was calculated for RAPD data, while the diversity of qualitative traits was described by Shannon genetic diversity index. Cluster analysis based on qualitative morphological characters showed clear separation of genotypes on the basis of their plant growth type. PC analysis performed for quantitative traits divided genotypes according to their maturity group. Grouping pattern based on molecular marker data was in agreement with pedigree of cultivars. A great similarity was found, primarily between the varieties under the same institution, and then among all examined varieties. Comparison of three methods in the assessment of diversity indicated that morphological markers might provide useful information in breeding process and allow classification by pedigree to some extent, but RAPD markers were found to be superior in assessing differences among genetically very similar genotypes.

AB  - Seed protein and oil content ate two main seed quality traits in soybean. Numerous studies confirm negative correlation between seed protein and oil concentration. Short season soybean varieties have higher protein concentration, while late cultivars have better oil content. The objective of this study was to evaluate 135 soybean accessions different maturity groups (00,0,L0,1) on the basis of their protein and oil concentration and to identify the genotypes with the best protein: oil ratio within each group. The accessions from soybean collection of the Maize Research Institute Zemun Polje (MRIZP) were analyzed for protein and oil content with a NIR spectroscopy. Cluster analysis using combined data of two traits was performed for genotypes of each maturity group. Categories of genotypes based on protein (low protein-LP, medium protein-MP, high protein-HP) and oil content (ow oil-LO, medium oil-MO, high oil-HO) were identified. Proportion of categories differed among groups. The majority of HPHO vatieties were found in maturity groups 00 and 0 (5 and 3 cultivars, respectfully).

AB  - Geneticists have been trying to explain adaptability and stability of a genotype in terms of a desirable combination of alleles expressed via epistasis. Stability determined in one set of data is very often stability of a genotype to a prevalent stress factor in a moment of carrying out the experiment. However, grain stability of a certain genotype can be a result of different factors, such as tolerance to drought, or to some important diseases and pests. Yield and yield stability of 15 maize hybrids were observed in 24 environments. The level of the interaction effect of studied maize hybrids was identified by the AMMI analysis, while a number of bands positively related to yield and stability of studied maize hybrids were identified by a genetic characterisation by RAPD markers. Bands positively related to yields were present to a greater extent in parents originating from the BSSS population, while bands positively related to stability were more present in parents originating from the Lancaster population.

Due to an unknown mechanism of genetic control and great environmental effects in the process of trait expression, morphological markers are often considered unreliable indicators of genetic relationships. Morphological characterisation of 19 maize inbreds was done according to the UPOV descriptor, while molecular characterisation was performed with RAPD markers. Based on the estimation of phenotypes according to the UPOV descriptor, the squared Euclidean distance was calculated and then, on the basis of this distance, a morphological similarity matrix was formed. Jaccard similarity coefficients were calculated on the basis of presence-absence of bands on gels in the RAPD analysis. When data were standardised, the comparison between morphological and genetic similarity of observed maize inbreds was done. The correlations varied from 0.47 (inbred L 217) to 0.76 (inbred L 86). The average value of correlations for all studied inbreds amounted to 0.64. Furthermore, the results of the cluster analysis for both markers, molecular and morphological, had high concordance with pedigree data. Environmental effects were decreased in morphological markers (according to the UPOV descriptor) by rescaling a measurement scale from a scale to an ordinal level of measurement and in such a way results of morphological markers approached results of molecular markers in the estimation of the genetic distance (GD) of maize inbred lines.

When data were standardised, the comparison between morphological and genetic similarity of observed maize inbreds was done. The correlations varied from 0.47 (inbred L 217) to 0.76 (inbred L 86). The average value of correlations for all studied inbreds amounted to 0.64. Furthermore, the results of the cluster analysis for both markers, molecular and morphological, had high concordance with pedigree data. Environmental effects were decreased in morphological markers (according to the UPOV descriptor) by rescaling a measurement scale from a scale to an ordinal level of measurement and in such a way results of morphological markers approached results of molecular markers in the estimation of the genetic distance (GD) of maize inbred lines.",

AB  - The origin and evolution of maize has been attracting attention of researchers of different profiles for decades. Although a few researchers in our country have explicitly been dealing with these issues, it is necessary to survey studies within this field. Not only because of educational reasons, but also because revealing secrets on the origin and evolution provides knowledge about maize genome, which can influence the improvement of current breeding of this very important crop. The enhancement of genetic variability of commercial material is another crucial challenge faced by maize breeders. Therefore, a segment of this study is a reminder indicating that collected and described landraces conserved in the genebank of the Maize Research Institute 'Zemun Polje' are germplasm valuable to breeding programmes intended for moderate climate. Some inbred lines (ZPPE25-10-1; NS796; R70Ž; NS568) developed in our scientific institutions using adapted landraces were of a great commercial importance for maize breeding programmes. However, little has been done on the improvement of landraces. Consequently, it is our opinion that some breeding efforts should be aimed at this topic in order to provide further progress in the maize breeding improvement.

AB  - In making decisions on the development of varieties and the identification of certain growing regions, the effects of genotype (G) and genotype by environment (GxE) are very important. Although the main genotype effect and the interaction effect should be partitioned, there is still a need for their integration in the yield, as both simultaneously affect a ranking of the particular genotype within a certain environment. The AMMI (Additive Main Effect and Multiplicative Interaction) analysis, as a hybrid model, provides appropriate partitioning. The AMMI2 model, capturing 98.4% of the treatment sum of squares, was used, and 12 observed environments were classified into three target environments. Hence, out of 15 commercial maize hybrids, used in the trial, the hybrids ZP-677, ZP-570 and ZP-732 were selected as carriers of maximum yields in three target environments. In this way, it was shown that even in a relatively small region a narrow adaptation of genotypes can be exploited.

Filipovic (2010): Visual assessment of sweet maize lines phenotype, according to UPOV descriptor, as indicator of heterosis- Genetika, Vol 42, No. 2, 313 - 322. The organisation of germplasm into genetically divergent groups is of extreme importance for the development of hybrid varieties in which the identification and exploitation of heterosis is very important for the final result of breeding. It can also be beneficial for breeding of self-pollination varieties, clones and synthetics. The discovery of heterotic groups in standard grain quality maize significantly improved the process of testing. The improvement in sweet maize was relatively modest in comparison to standard grain quality maize due to a relatively narrow genetic base of sweet maize, then poorly defined heterotic relations, scarce sources of germplasm that satisfy commercial standards, poor seed vigour, low quality of root and stalk, as well as, a short period of time for the estimation of yield and quality. The efficiency of hybrid breeding programmes would be significantly higher if heterosis could be predicted prior to the evaluation in the field. The application of the multivariate analysis method to data of phenotypic characterisation according to the UPOV Descriptor was an attempt to establish whether such a procedure can be beneficial for the determination of related groups and whether the phenotypic distance, obtained on the basis of a visual estimation of a plant group, can be an indicator of heterosis. Obtained results indicate that clustering is highly analogous to the pedigree. Since sweet maize breeders have at their disposal less significant genetic variability and search for the development and defining of heterotic groups, as such a procedure can be useful in both, the process of the hybrids development and the process of new inbreed development and genetic variability increasing. Certainly, further systematic studies aimed at this direction are necessary to reliably ascertain that the phenotypic distance is a justifiable indicator of heterosis.

AB  - Due to the interaction and noise in the experiments, yield trails for studying varieties are carried out in numerous locations and in the course of several years. Data of such trials have three principle tasks: to evaluate precisely and to predict the yield on the basis of limited experimental data; to determine stability and explain variability in the response of genotypes across locations; and to be a good guide for the selection of the best genotype for sowing under new agroecological conditions. The yield prediction without the inclusion of the interaction with the environments is incomplete and imprecise. Therefore, a great deal of breeding and agronomic studies are devoted to observing of the interaction via multilocation trials with replicates with the aim to use the interaction to obtain the maximum yield in any environment. Fifteen maize hybrids were analyzed in 24 environments. As the interaction participates in the total sum of squares with 6%, and genotypes with 2%, the interaction deserves observations more detailed than the classical analysis of variance (ANOVA) provides it. With a view to observe the interaction effect in detail in order to prove better understanding of genotypes, environments and their interactions AMMI (Additive Main Effect and Multiplicative Interaction) and the cluster analysis were applied. The partition of the interaction into the principal components by the PCA analysis (Principal Components Analysis) revealed a part of systematic variations in the interaction. These variations are attributed to the length of the growing season in genotypes and to the precipitation sum during the growing season in environments. Results of grouping by the cluster analysis are in high accordance with grouping observed in the biplot of the AMMI1 model.
AB  - Ogledi za ispitivanje varijeteta se izvode u brojnim lokacijama i u toku više godina i u osnovi imaju tri glavna zadatka: da precizno procene i predvide prinos na osnovu ograničenih eksperimentalnih podataka; da determinišu stabilnost i objašnjivu varijabilnost u odgovoru genotipova kroz lokacije; i da budu kvalitetan vodič za odabir najboljeg genotipa za setvu u novim agro-ekološkim uslovima.

abstract = "Due to the interaction and noise in the experiments, yield trails for studying varieties are carried out in numerous locations and in the course of several years. Data of such trials have three principle tasks: to evaluate precisely and to predict the yield on the basis of limited experimental data; to determine stability and explain variability in the response of genotypes across locations; and to be a good guide for the selection of the best genotype for sowing under new agroecological conditions. The yield prediction without the inclusion of the interaction with the environments is incomplete and imprecise. Therefore, a great deal of breeding and agronomic studies are devoted to observing of the interaction via multilocation trials with replicates with the aim to use the interaction to obtain the maximum yield in any environment. Fifteen maize hybrids were analyzed in 24 environments. As the interaction participates in the total sum of squares with 6%, and genotypes with 2%, the interaction deserves observations more detailed than the classical analysis of variance (ANOVA) provides it. With a view to observe the interaction effect in detail in order to prove better understanding of genotypes, environments and their interactions AMMI (Additive Main Effect and Multiplicative Interaction) and the cluster analysis were applied. The partition of the interaction into the principal components by the PCA analysis (Principal Components Analysis) revealed a part of systematic variations in the interaction. These variations are attributed to the length of the growing season in genotypes and to the precipitation sum during the growing season in environments. Results of grouping by the cluster analysis are in high accordance with grouping observed in the biplot of the AMMI1 model., Ogledi za ispitivanje varijeteta se izvode u brojnim lokacijama i u toku više godina i u osnovi imaju tri glavna zadatka: da precizno procene i predvide prinos na osnovu ograničenih eksperimentalnih podataka; da determinišu stabilnost i objašnjivu varijabilnost u odgovoru genotipova kroz lokacije; i da budu kvalitetan vodič za odabir najboljeg genotipa za setvu u novim agro-ekološkim uslovima.
