Gene effects and combining abilities of sunflower morphophysiological traits
(Paris : International Sunflower Association, 2008)
The development of sunflower hybrids with high genetic potentials for seed and oil yields requires
information on the GCA and SCA for agronomically important traits in the F1 generation. In this study were used seven new ...
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 ...
New sunflower hybrids tolerant of tribenuron-methyl
(Paris : International Sunflower Association, 2008)
Discovery of a tribenuron-methyl resistant wild Helianthus annuus L. population (ANN-KAN) reated an opportunity for expansion of a sunflower herbicide resistance breeding program. The aim of this work was the creation of ...
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 ...
Taxonomical position of Vavilovia formosa (Stev.) Fed. evidenced from morphological and molecular data
(Санкт-Петербург : ВИР, 2009)
The Fubeae Rehb. tribe includes numerous representatives of exclusive agricultural value and seems to be studied precisely. Despite this, some features of its system remain under discussion, namely relations between Orobus ...
Propadanje listova pšenice u zavisnosti od broja formiranih piknida Septoria tritici
(Beograd : Društvo za zaštitu bilja Srbije, 2009)
Prouzrokovač sive pegavosti lista i klasa, Septoria tritici Rob. ex Desm. (teleomorf Mycosphaerella graminicola (Fuckel) Schroeter, in Cohn) je parazit koji se javlja tokom cele vegetacije na svim nadzemnim delovima pšenice. ...
Virulentnost Blumeria graminis tritici u Srbiji (1990-2009)
(Beograd : Društvo za zaštitu bilja Srbije, 2009)
Pepelnica pšenice je ekonomski značajno oboljenje pšenice u Srbiji, čiji je prouzrokovač Blumeria (=Erysiphe) graminis tritici. Javlja se svake godine, a intenzitet zaraze zavisi od otpornosti sorte, agroklimatskih uslova ...
Virulence of Blumeria graminis tritici in Serbia (2000-2009)
(Abstract Book, 12th International Cereal Rusts Powdery Mildews Conference, 13-16 October 2009, Antalya, Turkey, 2009)
Blumeria graminis tritici, the causal agent of powdery mildew is a regular and economically important disease of wheat in Serbia. Infection intensity varies depending on wheat variety, climate conditions and agricultural ...
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 ...
