Assessment of quality of new Rf inbred lines resistant to broomrape rase E (Orobanche cumana Wallr.) developed from H. deserticola by interspecific hybridization
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
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 ...
Effect of storage period and chemical treatment on sunflower seed germination
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Hybrid sunflower seed, regularly protected with chemicals, is used for sowing in the second or the third year if not used in the first year after production. In that case, it is stored in warehouses, and the length of ...
Effect of silicon on sunflower growth and nutrient accumulation under low boron supply
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2013)
Study was focused on effect of silicon (Si) on growth and nutritional status of sunflower (Helianthus annuus L.) under low boron (B) external supply. Plants were grown under controlled environmental conditions in nutrient ...
Tolerance of sunflower (Helianthus annuus L.) to imazethapyr
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid 'Zoltan' (S) was investigated under controlled conditions. Hybrids grown in pots were treated ...
DNA polymorphism of wild sunflower accessions highly susceptible or highly tolerant to white rot on stalk
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
DNA polymorphism in accessions of Helianthus mollis, Helianthus rigidus and Helianthus tuberosus differing in level of resistance to stem white rot caused by Sclerotinia was evaluated in reactions with two RAPD primers, ...
Evaluation of resistance of new sunflower hybrids to broomrape in the breeding programs in Novi Sad
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Broomrape (Orobanche cumana Wallr.) presents a serious problem in sunflower production in a number of countries, it reduces sunflower seed yield and negatively affects other sunflower traits in sunflower production. Continued ...
Genotype by environment interactions for seed yield and oil content in sunflower (H. annuus L.) using AMMI model
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
Stability of 25 new sunflower hybrid combinations was compared against three standard hybrids in three locations. Seed yield per unit area and oil content in seed were measured using AMMI analysis. The tested combinations ...
Micropropagation of Helianthus maximiliani (Schrader) by shoot apex culture
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2001)
H. maximiliani was micropropagated using culture of shoot apices on modified Murashige and Skoog medium (DV). Further propagation of in vitro grown plants was done by culture of their nodal segments and shoot tips on the ...
Creating new genetic variability in sunflower using induced mutations
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
The objective of the study was to provide new genetic variability in important agronomic traits that can be exploited for improvement of sunflower production. Seeds of eight sunflower inbred lines from gene collection of ...
Use of SSR markers in identification of sunflower isogenic lines in late generations of backcrossing
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
In the present study, thirteen SSRs (Simple Sequence Repeats) were employed for screening the level of similarity between sunflower parental lines and progeny obtained in final stages of selection. Another aim of the study ...
