Pollen viability and seed set percentage of NS hybrids and their parental lines
(Paris : International Sunflower Association, 2004)
This research determined the pollen viability, percentage of seed set and seed yield of four commercial sunflower hybrids (HS-H-45, HS-H-111, NS-H-702 and VELJA) and their parental components (four male-fertile lines and ...
Towards Sclerotinia resistance: somatic hybridization between wild and cultivated sunflower
(Paris : International Sunflower Association, 2004)
The use of interesting characteristics from wild Helianthus species in sunflower breeding is limited by poor crossability or sterility of interspecific hybrids. Somatic hybridization by protoplast fusion is an efficient ...
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 ...
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 ...
Pojava bolesti ratarskih i povrtarskih useva kao posledica vremenskih uslova u 2003. godini / Occurrence of diseases in field and vegetable crops as a result of weather conditions in 2003
(Novi Sad : Institut za ratarstvo i povrtarstvo, 2004)
Ekstremni vremenski uslovi tokom zime, proleća i leta 2003. godine uticali su na pojavu bolesti ratarskih i povrtarskih useva, prouzrokujući značajne štete. Zima 2002/2003. obilovala je ledenim danima (temperature ispod ...
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 ...
Pregled proučavanja populacije Puccinia graminis Pers. f. sp. Tritici Erikss. et Henn. u Srbiji / Investigations of the Puccinia graminis f. sp. tritici Erikss. et Henn. population in Serbia - an overview
(Beograd : Društvo za zaštitu bilja Srbije, 2004)
Prva proučavanja populacije P. graminis tritici u Srbiji započeta su krajem 50-tih godina XX veka. U dosadašnjim proučavanjima razlikuju se dva perioda: prvi obuhvata identifikaciju fizioloških rasa pomoću standardnih ...
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 ...
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 ...
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 ...
