Determination of Yield, Oil and Fatty Acid Composition of Some Oil Sunflower (Helianthus annuus L) Genotypes İn Diyarbakır Conditions

Abstract

Oil seeds have an important place in human and animal nutrition because of their protein, fat, carbohydrate and mineral content content. This study was carried out to determination of yield, oil and fatty acid composition of some oil sunflower (Helianthus annuus L) genotypes in Diyarbakır conditions in 2018. The experiment was arranged in a randomized block design with three replications. In the study, thirteen different sunflower genotypes (Nantio, Turkuaz, Sanbro, Sanay MR, Armada CL, Bosfora, Tarsan 1018, LG 5580, Sirena, Transol, LG 5482, Coral and Tunca) were used as material. In the study plant height, head diameter, 1000 seed weight, seed yield,protein content, oil content, content of saturated and unsaturated fatty acids in the sunflower were investigated. The result showed that Significant differences were found between genotypes with respect to yield and oil quality components. According to mean values, the highest seed yield obtained from LG-5580 genotype (3813 kg ha-1). The highest values 1000 seed weight were found from LG-5580 (73.7 g) and Tunca (72.5 g) genotypes. The great oil content found as 44.6% from Armada CL genotype. The highest Linoleic acid content values were found by Tunca (55.7%) and LG-5580 (55.3%) genotypes, in adition to, the highest oleic values was determinated by Bosfora (37.8%) genotype. it was concluded that LG-5580 genotype could reliably be used in sunflower farming under ecological conditions of Diyarbakır province of Turkey.
