Influence of seed size grade on sunflower plant high
(Paris : International Sunflower Association, 2016)
The seed size is one of the seed quality components which affect the performance of the crop. In order to equalize the quality, the seeds are processed and packed by grade where seeds are separate by size and specific ...
Present status and future prospects of global confectionery sunflower production
(Paris : International Sunflower Association, 2016)
Although sunflower is mainly grown for the production of vegetable oils in the world, there
are many countries that prefer confectionery sunflower hybrids and varieties (landraces).
Confectionery sunflower breeding is ...
Efficacy of Trichoderma spp. isolates against Sclerotinia sclerotiorum on sunflower seedlings
(Paris : International Sunflower Association, 2016)
Trichoderma species are well known as effective antagonists to a variety of soil fungal pathogens. The aim of this research was to test the ability of Trichoderma spp. isolates, which previously indicated antagonistic ...
Screening for resistance to highly virulent races of sunflower broomrape (Orobanche cumana)
(Paris : International Sunflower Association, 2016)
Sunflower broomrape (Orobanche cumana Wallr.) is a major constraint for sunflower production in most production areas around the world, particularly in areas of Eastern and Southern Europe and the Middle East. The yield ...
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 ...
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 ...
Testing annual wild sunflower species for resistance to Orobanche cumana Wallr.
(Paris : International Sunflower Association, 2016)
Broomrape (Orobanche cumana Wallr.) is a holoparasitic weed that attacks the roots of sunflower (Helianthus annuus L.) causing yield losses in excess of 30%. It affects mostly warm and dry regions. Development of resistant ...
Variation in aggressiveness of Phoma macdonaldii isolates from three Balkan countries and Ukraine
(Paris : International Sunflower Association, 2016)
Phoma macdonaldii is a ubiquitous pathogen, affecting sunflower by premature leaf
senescence, stem cortical tissue necrosis and basal stem girdling. Sunflower genotypes
expressing partial resistance have been reported. ...
Combining ability and genetic components for seed yield in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2016)
Being one of the most important oil crops in the world main goals in sunflower breeding are
increased seed and oil yield per hectare. Bearing in mind breeding direction and global importance
of this oil crop objective ...
Correlations and path coefficient analysis of confectionery sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2016)
The most important criterion for introducing new confectionary hybrids into production is high protein yield. Breeding for increase of kernel protein content results in increased protein yield. Path coefficient analysis ...
