Creating new genetic variability in sunflower using induced mutations
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
The objective of the study was to provide new genetic variability in important agronomic traits that can be exploited for improvement of sunflower production. Seeds of eight sunflower inbred lines from gene collection of ...
Variability and stability of tuber yield of Jerusalem artichoke (Helianthus tuberosus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2001)
The objective of this paper was to estimate the genetic and ecological variation as well as the stability of tuber yield per plant, tuber number per plant and tuber size of Jerusalem artichoke based on the results of a ...
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 ...
Variability between helianfhus tuberosus accessions collected in the USA and Montenegro
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2002)
Morphological variability between accessions of H. tuberosus collected in Montenegro and the USA was investigated as well as possible effect of long- term cultivation or its absence and growing in different environmental ...
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 ...
Biomorphological association and path analysis in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2015)
In breeding process it is important to know the extent of association between the traits that affect the yield. Objective of this study was to determine genotypic and phenotypic correlation and path coefficients in 50 ...
