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 ...
Effect of storage period and chemical treatment on sunflower seed germination
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Hybrid sunflower seed, regularly protected with chemicals, is used for sowing in the second or the third year if not used in the first year after production. In that case, it is stored in warehouses, and the length of ...
Quantification of inulin content in selected accessions of Jerusalem artichoke (Helianthus tuberosus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2014)
Jerusalem artichoke is an excellent source of inulin. Inulin has valuable nutritional and functional attributes, and therefore it is needed to know inulin content in different accessions of Jerusalem artichoke tubers. We ...
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 ...
Assessment of quality of new Rf inbred lines resistant to broomrape rase E (Orobanche cumana Wallr.) developed from H. deserticola by interspecific hybridization
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Broomrape (Orobanche cumana Wallr.) presents a serious problem in sunflower production in a number of countries. The population of broomrape has been stable in Serbia for a long period of time, but the racial composition ...
Effect of silicon on sunflower growth and nutrient accumulation under low boron supply
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2013)
Study was focused on effect of silicon (Si) on growth and nutritional status of sunflower (Helianthus annuus L.) under low boron (B) external supply. Plants were grown under controlled environmental conditions in nutrient ...
Use of SSR markers in identification of sunflower isogenic lines in late generations of backcrossing
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
In the present study, thirteen SSRs (Simple Sequence Repeats) were employed for screening the level of similarity between sunflower parental lines and progeny obtained in final stages of selection. Another aim of the study ...
DNA polymorphism of wild sunflower accessions highly susceptible or highly tolerant to white rot on stalk
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
DNA polymorphism in accessions of Helianthus mollis, Helianthus rigidus and Helianthus tuberosus differing in level of resistance to stem white rot caused by Sclerotinia was evaluated in reactions with two RAPD primers, ...
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 ...
Evaluation of resistance of new sunflower hybrids to broomrape in the breeding programs in Novi Sad
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Broomrape (Orobanche cumana Wallr.) presents a serious problem in sunflower production in a number of countries, it reduces sunflower seed yield and negatively affects other sunflower traits in sunflower production. Continued ...
