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 ...
Heterosis for agronomically important traits in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Significant manifestation of heterosis for agronomically important traits is the main precondition for obtaining productive sunflower hybrids (Škorić et al., 2006). Development of high-yielding and stable sunflower hybrids ...
Influence of aging process on biochemical changes in sunflower seed
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2005)
This investigation was conducted in order to determine the degree of biochemical changes during accelerated and natural aging of sunflower seed. Five sunflower lines developed in Novi Sad, submitted to accelerated aging ...
Transferring Plasmopara halstedii resistance from annual wild into cultivated sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Twenty-nine populations of five wild annual sunflower species (H. annuus, H. petiolaris, H. argophyllus, H. praecox, H. debilis and H. neglectus) were screened for resistance to Plasmopara halstedii by the whole seed ...
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 ...
Effect of maturation period on seed quality; optimum time for desiccation in sunflower (helianthus annuus l) genotypes
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
To harvest a sunflower crop, it is important to bring moisture content, i.e moisture level in leaves, stems, heads and seed, to a level that permits normal work of combine harvester. In 2003, an experiment was established ...
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. ...
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 ...
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 ...
