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 ...
Path coefficient analysis of some yield components of sunflower
(Paris : International Sunflower Association, 2004)
In this study we examined mutual relationships among eight biological traits of sunflower (dry matter at flowering, leaf area, stature, stem and head diameters, number of filled seeds, 1000-seed mass and hull content) 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, ...
Gene actions for seed yield in sunflower (Helianthus annuus)
(Paris : International Sunflower Association, 2004)
Effects of additive and dominant genes and their interactions on the inheritance of seed yield in 10 sunflower hybrids developed by crossing five inbred lines derived from the synthetic NS-S-1 were analyzed in 2001 and ...
Use of additive-dominant model in genetic analysis of some quantitative caracteristics in sunflower
(European Association for Research on Plant Breeding, 2006)
A simple link between the expected means of quantitative traits of different generations (progenies) can be established if the mean values are dependant exclusively on additive and dominant gene effects. Th is study aims ...
Correlation between macronutrient content and sunflower resistance to Sclerotinia sclerotiorum measured by sclerotia infection of stem
(Paris : International Sunflower Association, 2008)
Nutrition of plants has a substantial impact on the predisposition of plants to be attacked or affected by pests and diseases. Since availability and nutrient quantity in the host plants is a limiting factor for Sclerotinia ...
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 ...
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 ...
Control of Orobanche cernua in imidazolinone-tolerant sunflower hybrids
(Amsterdam : International Parasitic Plant Society, 2004)
Sunflower breeding for tolerance to imidazolinone-based herbicides began in 1997, and many sunflower seed companies and institutes are actively developing so-called Clearfield* sunflower hybrids tolerant to imidazolinone-based ...
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 ...
