Exploring environmental determinants of the geographic distribution of broomrape (Orobanche cumana Wallr.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Broomrape is one of the most critical biotic constraints to sunflower crop production. In the most extended sunflower crop area of the world, distributed across Black sea region, this parasitic weed shows a high occurrence. ...
Association between seed yield and some morphological characteristics in sunflower / Povezanost između prinosa semena i nekih morfoloških svojstava suncokreta
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Objective of this study was to determine the divergence and association between seed yield and three morphological characteristics that are very important in sunflower breeding (plant height, head diameter and days to ...
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 ...
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 ...
Effect of location and harvesting date on yield and 1,000-seed weight of different sunflower genotypes
(Romanian Agricultural Research, 2012)
The effect of harvesting date on yield and 1,000-seed weight in sunflower genotypes was studied in India and Serbia. Harvest period began seven days after pollination and was performed on 10 occasions. The genotypes had ...
Seed dormancy of hybrids and parent lines of sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Sunflower is a plant species with a prominent period of seed dormancy. Physiological maturation period can be accelerated under laboratory conditions using methods for breaking seed dormancy such as: previous cooling at ...
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 ...
Testing sunflower inbred lines for tolerance to Phoma black stem / Iznalaženje izvora tolerantnosti za prouzrokovača crne pegavosti stabla suncokreta
(Institut za pesticide i zaštitu životne sredine, Beograd i Društvo za zaštitu bilja Srbije, Beograd, 2012)
Phoma black stem is caused by a widespread pathogen Phoma macdonaldii Boerema. The disease occurs regularly, causing damage by early defoliation and premature ripening. Complete resistance of sunflower to this disease has ...
