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 ...
Genotype by environment interactions for seed yield and oil content in sunflower (H. annuus L.) using AMMI model
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
Stability of 25 new sunflower hybrid combinations was compared against three standard hybrids in three locations. Seed yield per unit area and oil content in seed were measured using AMMI analysis. The tested combinations ...
Micropropagation of Helianthus maximiliani (Schrader) by shoot apex culture
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2001)
H. maximiliani was micropropagated using culture of shoot apices on modified Murashige and Skoog medium (DV). Further propagation of in vitro grown plants was done by culture of their nodal segments and shoot tips on the ...
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 ...
Phenotype variability and inheritance of plant height and branching in f1 generation of sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Highly variable populations of wild sunflower species were crossed with CMS cultivated lines. Variability was determined by measuring plant height and evaluating the type of branching. Mode of inheritance was tested by ...
Testing two isolates of diaporthe/phomopsis helianthi in a population of sunflower recombinant inbred lines
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2004)
Development of new, more aggressive isolates of Phomopsis helianthi in Serbia and Montenegro has been investigated. Two isolates of Phomopsis helianthi Yu 4 and Yu 12, had been found on the stem of NS-H-45, a highly tolerant ...
Interpretation of interactions in sunflower agronomic trials using multiplicative models and climatic information
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
A three-year experiment (2005, 2006, 2007) including three sunflower hybrids and eight sowing dates was carried out in order to study the impact of hybrid × sowing date interaction on oil yield of sunflower hybrids. With ...
Planting date effects on oil yield in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Oil yield per unit area is the ultimate target in growing high-oil sunflower genotypes. A research was carried out to determine planting date effects on oil yield, using three sunflower hybrids (Miro, Rimi, Pobednik), eight ...
A new association of ruderal weeds at Pančevački Rit in Serbia
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
A several-year study of distribution, phytocoenological differentiation, floristic composition and structure of ruderal flora and vegetation and relevant anthropogenic influence was conducted at Pančevački Rit in Serbia. ...
