Broomrape resistance in newly developed sunflower inbred lines
(Paris : International Sunflower Association, 2012)
Broomrape (Orebanche cumana Wallr.) is considered to be one of the most severe constrains in sunflower (Helianthus annuus L.) production. Rapid appearance of new races requires continuous search for new sources of resistance ...
Towards Orobanche resistance in sunflower - SSR analysis of a novel resistance source
(Paris : International Sunflower Association, 2012)
Broomrape is an aggressive parasite that penetrates through the roots of the host, absorbs nutrients directly from the vascular system and causes significant reduction in sunflower yield. Genetic resistance proved to be ...
Laboratory method for detection of tribenuron-methyl resistant sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2012)
Sulphonylureas are potent herbicide group that inhibit synthesis of three essential amino acids, valine, leucine and isoleucine. They have proven to be very effective in controlling broad-leaf weeds. Developing herbicide ...
Influence of seed processing on sunflower seed qualities
(Paris : International Sunflower Association, 2012)
In sunflower seed production it is important to obtain a high quality end product. This depends not only on field conditions and cultural practices applied but also on seed processing. During processing, seed grades are ...
Towards dihaploid production in sunflower - Selection of regeneration medium
(Paris : International Sunflower Association, 2012)
In sunflower breeding, it takes six to eight years to obtain inbred lines that are homozygous. Dihaploid production enables production of completely homozygous material for less than a year thus accelerating breeding ...
Modeling of environmental causes of hybrid by sowing date interaction in sunflower: a statistical approach
(Paris : International Sunflower Association, 2012)
The analysis of agronomic crop trials is usually complicated by the presence of hybrid by environment interaction, In this study the effect of selected environmental variables on hybrid by sowing date interaction in ...
Mode of inheritance and combining ability for seed yield and morphophisiological components of yield in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2012)
Used in this study were 13 new divergent cms inbred lines (A) originating from four interspecies populations originating from three annual (H. debilis, H. praecox runyoni, H. deserticola) and one perennial (A. resinosus) ...
Comparative study of abiotic environmental factors in broomrape (Orebanche cumana Wallr.) infested and non-infested sunflower areas of Serbia and Argentina
(Paris : International Sunflower Association, 2012)
In several main sunflower producing regions, the parasitic weed Orobanche cumana (Broomrape) is the most serious biotic crop constraint. This weed, native of the Caucasus region, has progressively migrated to all Eurasia. ...
Estimation of combining abilities in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2012)
In commercial production, sunflower hybrids are more represented than open pollinated varieties. The basic advantage of hybrids over varieties is that the hybrids allow the use of heterosis. Sunflower hybrids are more ...
Long-term influence of cultural practices on sunflower yields in commercial production in Serbia
(Paris : International Sunflower Association, 2012)
Sunflower is one of the main crops in Serbia, with average acreage of 200000 ha. Economic difficulties associated with the transition have caused significant reduction in sunflower yields. The aim of this paper was to ...
