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 ...
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, ...
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 ...
Towards sustainable downy mildew resistance in sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Breeding for downy mildew resistance is one of the major goals in sunflower breeding programmes. In the last few decades new sources of resistance have been discovered and the position of 11 resistance genes was established ...
Gene effect, combining ability and heterosis in sunflower morphophysiological traits
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
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 ...
Non-parametric stability analysis of sunflower oil yield trials
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
A three-year experiment (2008, 2009, 2010) on twenty sunflower hybrids grown in 13 (2010) to 15 (2009, 2008) locations in the region of Vojvodina and central Serbia was carried out in order to study GEI (genotype × environment ...
Development of sunflower genotypes resistant to downy mildew
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Sunflower is attacked by more than 40 different diseases of which only a certain number causes serious reduction of seed yield. One of the most damaging diseases is downy mildew, which is caused by the fungus Plasmopara ...
Seed dormancy of hybrids and parent lines of sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
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 ...
Screening wild sunflower species and F1 interspecific hybrids for resistance to broomrape
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Broomrape has become one of the most important threats to the cultivated sunflower. New sources of resistance genes are needed to maintain sunflower production. The objective of this research was to evaluate accessions of ...
