(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
The objective of this study was to analyze the variability and mutual dependence of the tuber weight per plant, tuber number per plant, average tuber weight and total sugars content in the tubers of 20 Jerusalem artichoke ...
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 ...
Effect of morphological and physiological traits on seed yield and oil content in sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Path coefficient analysis was used to separate direct and indirect effects of studied traits on seed oil content and seed yield, and to identify traits that could be used as selection criteria in sunflower breeding. ...
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 ...
