Vigor of sunflower and soybean aging seed
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Seed aging and deterioration affect seed vigor and viability. The characteristics of the chemical composition of oil crops seed are related to specific processes occurring in the seed during storage. This study was performed ...
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 ...
Seed viability of oil crops depending on storage conditions
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Changes occurring in seed during aging are significant as far as seed quality and longevity are concerned and are a consequence of the effects of different storage conditions. The chemical composition of seed with high oil ...
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 ...
Current status of broomrape (Orobanche cumana Wallr.) in Serbia
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2009)
Broomrape is the major issue in sunflower production in Serbia. Since its first occurrence, the species Orobanche cumana Wallr. had been responsible for considerable yield loss in some areas. In Serbia broomrape is present ...
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 ...
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 ...
Exploring environmental determinants of the geographic distribution of broomrape (Orobanche cumana Wallr.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Broomrape is one of the most critical biotic constraints to sunflower crop production. In the most extended sunflower crop area of the world, distributed across Black sea region, this parasitic weed shows a high occurrence. ...
Using new Rf inbred lines originating from an interspecific population with H. deserticola for development of sunflower hybrids resistant to broomrape
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2009)
One of the directions in sunflower breeding is the selection for resistance to broomrape. The population of broomrape has been stable in Serbia for a long period of time, but the racial composition has changed in recent ...
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 ...
