Abstract: In this study, ten breeding lines of safflower (Carthamus tinctorius L.) from Iran were evaluated in respect to technological and morphological traits for their utilization aspects in both food industry and agricultural applications. A considerable variation was found among the genotypes for hull, protein and oil content, iodine value, plant height, seed yield per plant, number of heads per plant and 100-seed weight. Oil content of seeds had a positive and considerable correlation with Iodine value and plant height and also, a negative correlation with seed yield per plant. Also, protein content recorded the highest positive association with oil content followed by plant height. Seed yield per plant showed positive and considerable correlation with hull content and number of days to flowering and a considerable negative correlation with protein content of seeds. Our results suggest that evaluated breeding lines of safflower could be valuable materials for breeding programs in which the main goals are improving oil yield and oil quality. The low correlation between oil content and seed yield in this study implied that it is possible to improve the seed yield and oil content simultaneously in safflower. Also, the results of this study indicated that improvement of seed yield could be achieved by selection for number of days to flowering.
