Genotype by environment interaction creates intricacy in yield prediction and is a challenge in agronomy and plant breeding. In order to assess yield stability of eight bread wheat genotypes in eight environments (four years under normal and drought stress conditions), eight randomized complete block design with three replications were conducted out in Kerman. Results analyzed as a combined design. Environment, genotypes and genotype by environment interaction were highly significant. Significant interaction pointed out different yield stability of evaluated cultivars. Stability was evaluated using environmental variance, coefficient of variation, Wricke's ecovalence, Shukla's stability variance, regression slope, deviation from regression slope, Additive Main effects and Multiplicative Interaction (AMMI) and AMMI Stability Value (ASV). Azar 2 and Kavir cultivars with high ranks in univariate stability parameters and the lowest ASV considered as the most stable genotypes. Shiraz was the most unstable cultivar in all univariate and multivariate methods. Considering mean over four years, Mahdavi and Shiraz had the highest yield performance in drought stress and normal conditions, respectively.
