Genotypic and environmental variability and stability of seed yield, oil content and fatty acids in high-oleic and high-linoleic safflower (Carthamus tinctorius L.) lines and cultivars

The present study was to determine the genotypic and environmental variability stability in seed yield, oil content, oleic linoleic acid of 10 safflower lines derived from a cross Dinçer 5-18-1 × Montola 2000 together with six cultivars under environments at five locations. effects genotypes, genotype environment interactions were highly significant (P < 0.01) for yield content. Averaged across all environments, lowest cultivar Olas (2 352 kg/ha), highest line Bay-Er 5 869 kg/ha). According mean (xi) regression coefficient (bi) values, 16 better adapted unfavourable conditions, whereas 1, 14 favourable conditions. content over 35%, recorded 15 Linas. best adaptability observed Olas. genotypes increased contents decreased north the. grown Southeastern Anatolia higher than other regions.
