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 ...
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 ...
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 ...
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) ...
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 ...
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 ...
