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 ...
Current status of broomrape (Orobanche cumana Wallr) in Serbia
(Paris : International Sunflower Association, 2008)
Broomrape is the parasitic plant that presents the major problem in sunflower production in Serbia. Since its first appearance in our country the species Orobanche cumana Wallr had been responsible for considerable yield ...
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 ...
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 ...
Imidazoline-resistant sunflower (Helianthus annuus): Inheritance of resistance and response towards selected sulfonylurea herbicides
(Paris : International Sunflower Association, 2000)
The objective of this investigation was to determine the reaction of wild sunflower to a
number of acetolactate synthase (ALS) inhibitors. We used a wild sunflower population from
Kansas known to be resistant to imazethapyr ...
Anther culture of sunflower cultivars
(Paris : International Sunflower Association, 2000)
Anthers of six sunflower cultivars in the stage of uninucleate microspores were placed
on six different culture media. Media were supplemented with basic MS (Murashige and
Skoog 1962) macro and micro salts, 30 g l-1 ...
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 ...
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 ...
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 ...
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 ...
