Evaluation of safflower genotypes selected from exotic varieties for grain and oil yields in limited irrigation condition

In order to study of variations among traits and clustering of genotypes regarding their similarities، an experiment with 100 safflower genotypes was conducted at research farm of Saveh Islamic Azad University. The experimental design was a 7٭7 simple lattice. The results of analysis of variance demonstrated that the differences among genotypes were highly significant (P < 0. 01) for all traits. The highest seed and oil yields were obtained from cultivars Goldasht and Padideh with 1700 and 433 kg/ha respectively. Phenotypic and genotypic correlations showed that the grain yield per plot is significantly correlated with oil yield، number of head and seed per head and number of secondary branches. The results of path coefficient analysis showed that increasing of seed yield has been associated with number of bulb per plant، secondary branches and number of seed per bulb with coefficients as 0. 610، 0. 480 and 0. 300 respectively.
