Determination of Some Morphological and Technological Characters in F2 Generation of Oleic and Mid-Oleic Type Safflower Genotypes (Carthamus tinctorius L.)

In this study, was conducted in 2018, 2019 and 2020 at Tekirdag Namik Kemal University Agriculture Faculty Department of Field Crops, it was aimed to determine morphological and technological traits of some oleic and mid-oleic type safflower genotypes developed by cross breeding. For this purpose, 11 F-2 hybrid genotypes obtained from a cross between Dincer 5-18-1 cultivar and PI 603208 genotype were used as material and compared to two standard oleic local cultivars and parents of these hybrids (Dincer 5-18-1, PI 603208, Olas ve Asol). In study to determine the agricultural and technological traits, plant height (cm), branch number, head number, head diameter (cm), 1000 seed weight (g), seed yield (kg da(-1)), hull ratio (%), oil content (%), oil yield (kg da(-1)) and fatty acid composition (%) were investigated. According to research findings, seed yield values of hybrid genotypes changed between 120.73-187.80 kg da(-1), oil content values 31.67-36.49% and oil yield values 40.43-63.92 kg da(-1) and showed a wide variation. The highest oil content among hybrid genotypes were obtained from the EC/ol-7 genotype (36.49%), while the highest seed yield and oil yield among genotypes were obtained from the EC/ol-8 genotype (187.80 and 63.92 kg da(-1) respectively). The highest oleic oil content among hybrid genotypes was obtained from the EC/ol-11 genotype (61.79%). In this study, it was determined that 5 genotypes in terms of oil content, seed yield and oleic acid composition (EC/ol 5, EC/ol 6, EC/ol 7, EC/ol 8 and EC/ol 11) are superior of the other genotypes in F-2 generation. In addition, with the other genotypes, both stable and hopeful ones will be determined the next generations (F-3 and F-4).
