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 ...
The wild sunflowers collection in Novi Sad
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Lowered genetic variability in the cultivated sunflower and use of interspecies hybridization in sunflower breeding were the main reasons to establish the wild species collection. Wild species were collected during collecting ...
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 ...
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 ...
Towards sustainable downy mildew resistance in sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Breeding for downy mildew resistance is one of the major goals in sunflower breeding programmes. In the last few decades new sources of resistance have been discovered and the position of 11 resistance genes was established ...
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 ...
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. ...
