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 ...
Towards Sclerotinia resistance – In vitro screening of wild sunflower species
(Paris : International Sunflower Association, 2008)
This paper presents the work on testing the possibility of the use of in vitro screening for determination of wild Helianthus species resistance to Sclerotinia. For this purpose, micropropagated plants of different accessions ...
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 ...
Direct and indirect effects of morphophysiological traits on seed yield of sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2008)
In this paper, we have studied the interdependence of seed yield per plant and the following
morphophysiological traits: total leaf number per plant, total leaf area per plant, plant height, total seed number per head, ...
Effect of the environment on the chemical composition and some other parameters of sunflower seed quality
(Paris : International Sunflower Association, 2008)
Considering the area of sunflower cultivation in the world, the profit made by selling the seed varieties and sunflower hybrids, the number of companies whose business activity is related to production and selling of ...
Relationship between genetic distance and heterosis based on quantitative traits and SSR markers in sunflower
(Paris : International Sunflower Association, 2008)
The objective of this study was to determine the relationship between SSR based genetic distance (GD) of new NS sunflower inbred lines for most important agronomic traits and heterosis. Twenty three sunflower inbred lines ...
Gene effects and combining abilities of sunflower morphophysiological traits
(Paris : International Sunflower Association, 2008)
The development of sunflower hybrids with high genetic potentials for seed and oil yields requires
information on the GCA and SCA for agronomically important traits in the F1 generation. In this study were used seven new ...
