To analyze the genotype x environment interaction and determine the yield stability and adaptability of barley genotypes, 19 genotypes of barley including 13 Iranian and 6 international genotypes were evaluated in ten different locations during1998-2001 cropping seasons, using AMMI model. Results showed that the main additive effects of genotype and environment and multiplicative interaction effect of genotype x environment were significant that indicated specific adaptability of the genotypes with special environments. In order to identify stable and adaptable genotypes, AMMI model was used. Stability parameters used in AMMI model consisted of SIPC1, EV1 and AMGE1. In addition biplot technique was used to identify appropriate genotypes to special locations. Results showed that genotypes Kozir, Dundy and Schulyer/L.640 with the lowest interaction, and genotypes K-201/3-2, Walfajre/Wl-2291 and 73-M4-30 with the highest interaction were the most stable and unstable genotypes, respectively. Furthermore, genotypes Arass/Cyclon, L.131//Cg/CM and Cl-10143/Walfajre were more suitable for Karaj, genotype Vavilon for Miandoab and genotypes Kavir/Badia"s" and K-201l3-2 for Mashhad
