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 ...
Gene actions affecting sunflower resistance to Sclerotinia sclerotiorum measured by sclerotia infections of roots, stems and capitula
(Paris : International Sunflower Association, 2004)
Five sunflower inbred lines were crossed with one restorer line and F1, F2, BC1P1 and BC1P2 progenies were produced. Generation means analysis was done for all six generations, as well as the scaling test. The additive-dominance ...
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 ...
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 ...
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 ...
New sunflower hybrids tolerant of tribenuron-methyl
(Paris : International Sunflower Association, 2008)
Discovery of a tribenuron-methyl resistant wild Helianthus annuus L. population (ANN-KAN) reated an opportunity for expansion of a sunflower herbicide resistance breeding program. The aim of this work was the creation of ...
Inheritance of seed size in sunflower
(Paris : International Sunflower Association, 2000)
There are several ways to increase yield per unit area. One of the most commonly used ways is to increase seed size and seed number per head while maintaining or raising the number of plants per unit area. Breeding for ...
Development of inbred lines of sunflower with various oil qualities
(Paris : International Sunflower Association, 2000)
The cultivated sunflower (Helianthus annuus) is one of most important oil crops in the
world. Although sunflower is primarily grown for extraction of oil there is a limited
production of non-oilseed types used for ...
The appropriate technique for collecting and measuring the amount of floral nectar in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2008)
The available techniques for collecting and measuring the amount of floral nectar are applicable but often found to be unrepresentative. Centrifugation yields larger samples but they also include nectar that is not actually ...
