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 ...
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 ...
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 ...
Genetic purity of sunflower hybrids determined on the basis of isozymes and seed storage proteins
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
Maintenance of genetic uniformity of lines and hybrids is a prerequisite for successful production and placement of commercial hybrid seed on the market. Genetic purity of seed as specific seed trait is of great significance ...
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 ...
Development of sunflower hybrids with different oil quality
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
The cultivated sunflower (Helianthus annuus L.) is one of most important oil crops of the world. Although sunflower is primarily grown for extraction of its seed oil there is a limited production of non-oilseed sunflower ...
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 ...
The wild sunflowers collection in Novi Sad
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Lowered genetic variability in the cultivated sunflower and use of interspecies hybridization in sunflower breeding were the main reasons to establish the wild species collection. Wild species were collected during collecting ...
Effect of harvest date on seed viability of different sunflower genotypes
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Effect of harvest date on seed viability has been examined in 3 different sunflower genotypes. Harvesting started 7 days after fertilization. It was done 10 times, at 3-4-day intervals. Seed moisture was determined before ...
An analysis of heterotic potential for agronomically important traits in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Study of inbreeding and heterosis in sunflower has been taking place for over 80 years now. Practical application of the phenomenon of heterosis in this species began after the discovery of a suitable source of cytoplasmic ...
