Inheritance of some yield components in sunflower
(Paris : International Sunflower Association, 2004)
In order to study the mode of inheritance and gene effects for seed set, autofertility and self-fertility, half diallel crosses with five divergent sunflower inbred lines were made. The effects of additive, dominant and ...
Effects of genotype, growing conditions, and several parameters of sunflower attractiveness for bee visitation
(Paris : International Sunflower Association, 2004)
Effects of genotype and fertilizers on the production and availability of nectar and visitation by pollinators were analyzed. We analyzed four sunflower hybrids (Velja, NS-H-45, NS-H-111 and NS-H-702) and their parental ...
Achievements of sunflower breeding at the IFVC in Novi Sad
(Paris : International Sunflower Association, 2004)
Novi Sad breeding materials and some wild species of the genus Helianthus were used to create new genetic variability in cultivated sunflower. Our breeding program during 1997-2003 had several directions, and greenhouses ...
Genetic divergence in sunflower (Helianthus annuus) inbreds
(Paris : International Sunflower Association, 2004)
Increase in seed yield is the main objective of sunflower breeding programs. Genetic variability is the basic prerequisite for each breeding program. Determination and knowledge of genetic variability facilitate the selection ...
Correlation of yield components and seed yield per plant in sunflower (Helianthus annuus)
(Paris : International Sunflower Association, 2004)
Studied in this paper was the interdependence of six morphophysiological sunflower traits (petiole angle, petiole length, total leaf number per plant, total leaf area per plant, plant height and head diameter) and their ...
Changes in seed oil content of sunflower (Helianthus annuus L.) as affected by harvesting date
(Paris : International Sunflower Association, 2008)
The paper studied the effect of harvesting date on seed oil accumulation in three sunflower genotypes. Harvesting began seven days after pollination and continued at three to four day intervals until ten harvests were ...
The use of new Rf inbred lines originating from interspecific population with H. deserticola for the production of sunflower hybrids resistant to broomrape
(Paris : International Sunflower Association, 2008)
One of the directions in sunflower breeding is selection for the resistance to broomrape. The population of broomrape has been stable in Serbia for a longer period of time, but the racial composition has changed in recent ...
Uticaj globalnih klimatskih promena na pojavu i širenje volovoda u Srbiji
(Beograd : Društvo za zaštitu bilja Srbije, 2009)
Promena klime ne utice samo na gajenje biljke vec dovodi do promene u razvoju stetnih organizama. Klimatske promene uticu na rezistentnost biljaka domacina i dovode do promena u interakciji domacin patogen. Najcesce promene ...
