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. ...
Using new Rf inbred lines originating from an interspecific population with H. deserticola for development of sunflower hybrids resistant to broomrape
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2009)
One of the directions in sunflower breeding is the selection for resistance to broomrape. The population of broomrape has been stable in Serbia for a long period of time, but the racial composition has changed in recent ...
Changes of fatty acids content and vigor of sunflower seed during natural aging
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Sunflower seed aging during storage affects seed vigor and content of fatty acids. In order to reveal severity of their influence, the following vigor tests were applied: standard laboratory germination test, cold test and ...
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 ...
Seed dormancy of hybrids and parent lines of sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Sunflower is a plant species with a prominent period of seed dormancy. Physiological maturation period can be accelerated under laboratory conditions using methods for breaking seed dormancy such as: previous cooling at ...
