Gene effect, combining ability and heterosis in sunflower morphophysiological traits
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
Four interspecies populations, originating from three annual (H. debilis, H. praecox, H. deserticola) and one perennial (H. resinosus) wild species, were used to produce 13 new (cms) inbred lines with cytoplasmic male ...
Combining ability for oil content and its correlations with other yield components in sunflower (helianthus annuus l)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Oil yield is a major characteristic of each sunflower hybrid (Škorić et al 2005). To be able to develop new high-oil sunflower hybrids by the method of interspecific hybridization, it is necessary to have information on ...
Testing two isolates of diaporthe/phomopsis helianthi in a population of sunflower recombinant inbred lines
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2004)
Development of new, more aggressive isolates of Phomopsis helianthi in Serbia and Montenegro has been investigated. Two isolates of Phomopsis helianthi Yu 4 and Yu 12, had been found on the stem of NS-H-45, a highly tolerant ...
The use of PCR-based markers in the evaluation of resistance to downy mildew in ns-breeding material
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2004)
The aim of this work was the application of previously developed and development of new PCR markers for the evaluation of sunflower resistance to downy mildew. Twenty sunflower inbred lines were investigated. Plant resistance ...
Use of oxalic acid for screening intact sunflower plants for resistance to Sclerotinia in vitro
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2002)
Three sunflower inbred lines differing in resistance to Sclerotinia were grown on nutritive medium supplemented with different concentrations of oxalic acid. After two weeks of culture, plant height, fresh and dry weight ...
Influence of aging process on biochemical changes in sunflower seed
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2005)
This investigation was conducted in order to determine the degree of biochemical changes during accelerated and natural aging of sunflower seed. Five sunflower lines developed in Novi Sad, submitted to accelerated aging ...
An analysis of heterotic potential for agronomically important traits in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Study of inbreeding and heterosis in sunflower has been taking place for over 80 years now. Practical application of the phenomenon of heterosis in this species began after the discovery of a suitable source of cytoplasmic ...
Seed viability of oil crops depending on storage conditions
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Changes occurring in seed during aging are significant as far as seed quality and longevity are concerned and are a consequence of the effects of different storage conditions. The chemical composition of seed with high oil ...
Planting date effects on oil yield in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Oil yield per unit area is the ultimate target in growing high-oil sunflower genotypes. A research was carried out to determine planting date effects on oil yield, using three sunflower hybrids (Miro, Rimi, Pobednik), eight ...
Effect of time of desiccation on oil content in different sunflower hybrids
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2001)
Chemical desiccation with Reglone Forte has been tried in production fields under four sunflower hybrids. Reglone Forte (2 l/ha) was applied at 7-day intervals from the end of pollination till maturity. Seed moisture was ...
