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 ...
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 ...
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 ...
Broomrape in Serbia from its occurence till today
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2009)
Epiphytotic occurrence of broomrape was observed in Serbia for the first time in 1951, then again at the beginning of the 1990s which continues up to date. It is hypothesized that the new race was introduced by confectionery ...
Classification of Jerusalem artichoke accessions by linear discriminant analysis of mineral concentration in tubers and leaves
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
Linear discriminant analysis (LDA) was used to classify 138 accessions of Jerusalem artichoke (Helianthus tuberosus L.). The analysis was performed using mineral element concentrations of tubers and leaves for N, P, Ca, ...
Radiosensitivity of sunflower inbred lines to mutagenesis
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
For much of the past century, mutagenesis has gained popularity in plant genetics research as a means of inducing novel genetic variation. Induced mutations have been applied for the past 40 years to produce mutant cultivars ...
Yield component analysis and diversity in Jerusalem artichoke (Helianthus tuberosus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
The objective of this study was to analyze the variability and mutual dependence of the tuber weight per plant, tuber number per plant, average tuber weight and total sugars content in the tubers of 20 Jerusalem artichoke ...
Broomrape seed germination on nutritive media and possibility of its biological control
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
In tests of sunflower hybrids' susceptibility to broomrape under artificial inoculation conditions, a high germination rate of broomrape seed used for infestation is prerequisite. On the other hand, one of the ways to ...
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 ...
