Line x tester analysis for plant height and head diametar in sunflower (Helianthus annuus)
(Paris : International Sunflower Association, 2004)
One of the prime tasks of sunflower breeding is the development of inbred lines by interspecific hybridization in order to obtain high-yielding and stable hybrids. This study used seven new divergent (A) CMS inbreds obtained ...
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 ...
Pollen viability and seed set percentage of NS hybrids and their parental lines
(Paris : International Sunflower Association, 2004)
This research determined the pollen viability, percentage of seed set and seed yield of four commercial sunflower hybrids (HS-H-45, HS-H-111, NS-H-702 and VELJA) and their parental components (four male-fertile lines and ...
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 ...
Gene effects and combining abilities for 1000-seed mass in sunflower (Helianthus annuus)
(Paris : International Sunflower Association, 2004)
Significant differences in the mean values of 1000-seed mass were found among the sunflower (Helianthus annuus L.) genotypes studied (eight inbred lines and 15 F1 hybrids). The mean value of 1000-seed mass was 46.88 g in ...
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 ...
Towards Sclerotinia resistance: somatic hybridization between wild and cultivated sunflower
(Paris : International Sunflower Association, 2004)
The use of interesting characteristics from wild Helianthus species in sunflower breeding is limited by poor crossability or sterility of interspecific hybrids. Somatic hybridization by protoplast fusion is an efficient ...
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 ...
Path coefficient analysis of some head and seed characteristics in sunflower
(Paris : International Sunflower Association, 2004)
The 1000-seed mass is one of the three most important yield components in sunflower. Using correlation analysis, we studied the interrelationship of several yield components (1000-seed mass, test weight, head diameter, ...
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 ...
