Transferring Plasmopara halstedii resistance from annual wild into cultivated sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Twenty-nine populations of five wild annual sunflower species (H. annuus, H. petiolaris, H. argophyllus, H. praecox, H. debilis and H. neglectus) were screened for resistance to Plasmopara halstedii by the whole seed ...
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 ...
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 water stress on yield and evapotranspiration of sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2009)
An experiment was conducted at Rimski Šančevi Experiment Field of Institute of Field and Vegetable Crops in Novi Sad during 2000 - 2005. The soil in the experimental plot was calcareous chernozem on loess terrace. Using ...
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 ...
A new association of ruderal weeds at Pančevački Rit in Serbia
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
A several-year study of distribution, phytocoenological differentiation, floristic composition and structure of ruderal flora and vegetation and relevant anthropogenic influence was conducted at Pančevački Rit in Serbia. ...
Effect of maturation period on seed quality; optimum time for desiccation in sunflower (helianthus annuus l) genotypes
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
To harvest a sunflower crop, it is important to bring moisture content, i.e moisture level in leaves, stems, heads and seed, to a level that permits normal work of combine harvester. In 2003, an experiment was established ...
Heterosis for agronomically important traits in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Significant manifestation of heterosis for agronomically important traits is the main precondition for obtaining productive sunflower hybrids (Škorić et al., 2006). Development of high-yielding and stable sunflower hybrids ...
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 ...
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 ...
