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 ...
Pollen viability and seed set percentage of NS hybrids and their parental lines
(Paris : International Sunflower Association, 2004)
This research determined the pollen viability, percentage of seed set and seed yield of four commercial sunflower hybrids (HS-H-45, HS-H-111, NS-H-702 and VELJA) and their parental components (four male-fertile lines and ...
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 ...
Correlation between macronutrient content and sunflower resistance to Sclerotinia sclerotiorum measured by sclerotia infection of stem
(Paris : International Sunflower Association, 2008)
Nutrition of plants has a substantial impact on the predisposition of plants to be attacked or affected by pests and diseases. Since availability and nutrient quantity in the host plants is a limiting factor for Sclerotinia ...
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 ...
Sunflower seed oil content depending on the seedling type
(Paris : International Sunflower AssociationNovi Sad : Institute of Field and Vegetable Crops, 2022)
The problem of the appearance of abnormal seedlings is often manifested in sunflower seed germination testing. Abnormality is most often caused by a lack of primary root. However, when sown in a field, abnormal seedlings ...

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 ...
Effect of sowing date on head diameter in sunflower
(Paris : International Sunflower Association, 2016)
Head diameter is very important trait in the sunflower seed yield structure. The size of head diameter influences the number of flowers and seeds per head which directly influence the seed yield per plant. In order to ...
Effects of genotype, growing conditions, and several parameters of sunflower attractiveness for bee visitation
(Paris : International Sunflower Association, 2004)
Effects of genotype and fertilizers on the production and availability of nectar and visitation by pollinators were analyzed. We analyzed four sunflower hybrids (Velja, NS-H-45, NS-H-111 and NS-H-702) and their parental ...
