The objectives of this study were to analyze genotype by environment (GE) interactions on the seed yield of 19 safflower genotypes by the additive main effects and multiplicative interactions (AMMI) model and to evaluate genotype (G), environment (E) and GE interactions using statistics parameter i.e. AMMI stability value (ASV) and ecovalence (W2i). The trials were conducted at three locations: Shirvan, Sararood and Khoramabad for two successive cropping seasons (2010-12). Main effects due to E, G, and GE interactions as well as two first interaction principal components (IPCA1-2) were found to be significant. AMMI biplot was able to distinguish stable genotypes and environments, with high and low genotype discrimination ability. The genotypes 6 and 10 with higher mean seed yield than total mean were to be most stable genotypes, while the genotypes 18 and 3 with the highest contribution to GE interaction were to be most instable.
