Development of sunflower hybrids with different oil quality
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
The cultivated sunflower (Helianthus annuus L.) is one of most important oil crops of the world. Although sunflower is primarily grown for extraction of its seed oil there is a limited production of non-oilseed sunflower ...
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 ...
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 ...
Current status of broomrape (Orobanche cumana Wallr.) in Serbia
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2009)
Broomrape is the major issue in sunflower production in Serbia. Since its first occurrence, the species Orobanche cumana Wallr. had been responsible for considerable yield loss in some areas. In Serbia broomrape is present ...
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 ...
Inheritance of increased oleic acid content in sunflower seed oil / Nasleđivanje povećanog sadržaja oleinske kiseline u ulju suncokreta
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2000)
The inheritance of increased (mid) oleic acid content about 62% of an inbred line, LG27, was studied in the crosses with high oleic HA89OL (89%), high oleic LG26OL (86%) and low oleic LG28 (22%). Fatty acid composition of ...
Effect of naphthenic acids on formation of adventitious roots in sunflower cuttings
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2003)
The paper describes a study of the effect of salts of natural naphthenic acids on the rooting of young sunflower cuttings and latteral branching of interspecies sunflower hybrids. Naphthenic acids were obtained by alkaline ...
Screening wild sunflower species and F1 interspecific hybrids for resistance to broomrape
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Broomrape has become one of the most important threats to the cultivated sunflower. New sources of resistance genes are needed to maintain sunflower production. The objective of this research was to evaluate accessions of ...
Non-parametric stability analysis of sunflower oil yield trials
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
A three-year experiment (2008, 2009, 2010) on twenty sunflower hybrids grown in 13 (2010) to 15 (2009, 2008) locations in the region of Vojvodina and central Serbia was carried out in order to study GEI (genotype × environment ...
Exploring environmental determinants of the geographic distribution of broomrape (Orobanche cumana Wallr.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Broomrape is one of the most critical biotic constraints to sunflower crop production. In the most extended sunflower crop area of the world, distributed across Black sea region, this parasitic weed shows a high occurrence. ...
