To study genotype Í environment interaction, stability of eighteen new winter safflower genotypes together with two cultivars Padideh and Goldasht were evaluated in four different environmental conditions of Karaj, Isfahan,, Darab and Zabol. The experiment was in a randomized complete block design with four replications carried out for three years( 2006 -2009 ). The analysis of variance for seed yield showed significant differences among the genotypes. The effects of genotype × year, genotype × location and genotype × year × location were also significant. Stability parameters such as S2i , S2di , CVi , W2i , δ 2 i , bi and SDR were estimated for each genotype, and based on the mean of seed and oil yields, coefficient of regression equal to unity, less deviation from regression and other stability parameters, genotype K.W.2 with the highest seed yield (2862.2 kgha-1) and good stability was selected as a desirable genotype.
