To determine yield stability in bread wheat lines and cultivars for dry and warm areas of Iran, 18 elite lines together with Chamran cultivar as check were studied in a randomized complete block design with three replications at six warm and dry stations (Ahvaz, , Dezful, Darab, Zabol, Iranshahr and Khorramabad) during 2005- 2007 cropping seasons. The results revealed that the interactions of location × year and location × year × genotype were significant. Stability analysis for grain yield of genotypes based on Eberhart and Russell linear regression coefficient, Wrick’s ecovalence, Shukla’s stability variance, simultaneous selection index, non-parametric statistic method (mean rank of yield, standard deviation of rank of yield, and yield index ratio), AMMI and SHMM models, the genotype no. 11 (Weebill 1) was determined as the most stable genotype. AMMI and SHMM models were also suggested as efficient methods for determining of stable genotypes in breeding programs based on the results of these experiments.
