Modeling of environmental causes of hybrid by sowing date interaction in sunflower: a statistical approach
(Paris : International Sunflower Association, 2012)
The analysis of agronomic crop trials is usually complicated by the presence of hybrid by environment interaction, In this study the effect of selected environmental variables on hybrid by sowing date interaction in ...
Mode of inheritance and combining ability for seed yield and morphophisiological components of yield in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2012)
Used in this study were 13 new divergent cms inbred lines (A) originating from four interspecies populations originating from three annual (H. debilis, H. praecox runyoni, H. deserticola) and one perennial (A. resinosus) ...
Effect of desiccation moment on 1000-seed weight in sunflower / Uticaj momenta desikacije na masu 1000 semena suncokreta
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
The experiment was carried out at Rimski Šančevi during 2009 in order to investigate the effect of chemical desiccation on 1000-seed weight in three sunflower lines, and to determine the optimal moment for performing ...
Estimation of combining abilities in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2012)
In commercial production, sunflower hybrids are more represented than open pollinated varieties. The basic advantage of hybrids over varieties is that the hybrids allow the use of heterosis. Sunflower hybrids are more ...
Long-term influence of cultural practices on sunflower yields in commercial production in Serbia
(Paris : International Sunflower Association, 2012)
Sunflower is one of the main crops in Serbia, with average acreage of 200000 ha. Economic difficulties associated with the transition have caused significant reduction in sunflower yields. The aim of this paper was to ...
Morphological characterization of UGA-SAM1 sunflower association mapping population
(Paris : International Sunflower Association, 2016)
In order to use germplasm collections more efficiently and effectively, it is important to characterize the diversity of the germplasm. The objective of this study was to assess morphological diversity of a sunflower ...
Feasibility of keeping F, interspecific sunflower hybrids
(Paris : International Sunflower Association, 2012)
Helianthus genus comprises 14 annual and 37 perennial species. Perennial species reproduce vegetatively (rhizomes, tubers) so that it is relatively easy to maintain them in ex situ collections in the field. Hybrid plants ...
Sunflower breeding for production stability - Example of NS hybrids
(Paris : International Sunflower Association, 2018)
Sunflower breeding process involves the selection of hybrids which have the tendency to maximize yield potential and its stability in different growing regions. Perspective genotypes are usually evaluated in different ...
Epicoccum nigrum pathogen of sunflower seed in Serbia
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
Forty samples of sunflower seed (Helianthus annuus L.) were analyzed in period 2017-2018. Based on morphological characterization and pathogenicity test the fungus isolated from the tissues were initially identified as ...
Cytogenetic study of helianthus strumosus and its F1 and BC1F1 hybrids with cultivated sunflower
(Paris : International Sunflower Association, 2016)
Helianthus strumosus L. is represented in Novi Sad collection of wild sunflower species with large number of accessions (14 with seed reserves and 20 in the field collection). It is often used as a source of resistance to ...
