Field trials of the study were carried out during 2008- 09 and 2009-10 growing seasons under the rainfed conditions of five different locations of the Southeastern Anatolia region of Turkey. The field trials were established according to randomized blocks design with three replications. Additive main effects and multiplicative interactions analysis (AMMI) showed that the effect of environments on genotype × environment interactions were found quite high levels for biological yield trait. The first two principal component axes (IPCA 1 and IPCA 2) were found highly significant (P<0.01), and they accounted for 74.81% of the total genotype by environmental interaction. AMMI analysis revealed that Ege Beyazı-79 (G6) cultivar has the best stability in terms of biological yield.
