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 ...
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 ...
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 ...
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 ...
Evaluation of NS sunflower hybrids in small-plot trials via hybrid × location interaction / Ocena NS hibrida suncokreta u mikro-ogledima preko interakcije hibrid x lokalitet
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
The aim of this study was to evaluate NS sunflower hybrids on the basis of the results of seed yield, seed oil content and oil yield obtained in a network of small-plot trials in Serbia in 2011. The trial included 9 hybrids ...
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 ...
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. ...
