Control of Orobanche cernua in imidazolinone-tolerant sunflower hybrids
(Amsterdam : International Parasitic Plant Society, 2004)
Sunflower breeding for tolerance to imidazolinone-based herbicides began in 1997, and many sunflower seed companies and institutes are actively developing so-called Clearfield* sunflower hybrids tolerant to imidazolinone-based ...
Gene actions affecting sunflower resistance to Sclerotinia sclerotiorum measured by sclerotia infections of roots, stems and capitula
(Paris : International Sunflower Association, 2004)
Five sunflower inbred lines were crossed with one restorer line and F1, F2, BC1P1 and BC1P2 progenies were produced. Generation means analysis was done for all six generations, as well as the scaling test. The additive-dominance ...
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 ...
Screening for virulence of Blumeria graminis tritici using mobile nurseries
(Novi Sad : University of Novi Sad, Faculty of Agriculture, 2004)
Blumeria graminis tritici, the causal agent of Powdery mildew, is a regular and economically important disease of wheat in Serbia and a major disease problem in wheat crops in Europe, particularly in northern and western ...
Effects of genotype, growing conditions, and several parameters of sunflower attractiveness for bee visitation
(Paris : International Sunflower Association, 2004)
Effects of genotype and fertilizers on the production and availability of nectar and visitation by pollinators were analyzed. We analyzed four sunflower hybrids (Velja, NS-H-45, NS-H-111 and NS-H-702) and their parental ...
Achievements of sunflower breeding at the IFVC in Novi Sad
(Paris : International Sunflower Association, 2004)
Novi Sad breeding materials and some wild species of the genus Helianthus were used to create new genetic variability in cultivated sunflower. Our breeding program during 1997-2003 had several directions, and greenhouses ...
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 ...

Correlation of yield components and seed yield per plant in sunflower (Helianthus annuus)
(Paris : International Sunflower Association, 2004)
Studied in this paper was the interdependence of six morphophysiological sunflower traits (petiole angle, petiole length, total leaf number per plant, total leaf area per plant, plant height and head diameter) and their ...
Influence of several wheat pathogens on the leaf rust development
(Novi Sad : University of Novi Sad, Faculty of Agriculture, 2004)
The investigations of the interactions between pathogens could be interrupted by single strong development of each on the same plant. The adequate methods were not developed until nowadays. The protection by fungicides ...
