Abstract

In order to evaluate the stability and determine the highest yielding variety, 20 genotypes of hulless barley were studied in this research. The experiment was conducted in a randomized complete block design with three replication in six locations (Karaj, Esfahan, Nyshaboor, Yazd, Birjand, Zarghan) for two years (2001-2003). Simple and combined analysis of variances showed that there were significant different between genotypes, In order to evaluate interactions and determine the adaptation of genotypes study in cluding: Environment variance, Environmental coefficient of variation, Eberhart and Russell’s regression method, Lin and Binn’s years within location mean squares method, the years within location environmental coefficient of variation and Non-parametric methods of deviation from rank and yield index. The obtained results through all these methods were nearly analogous. ICNB93-328 and ALELI/4/MOLA/2 genotypes were identified as stable genotypes. GLORIA genotype was recognized specially for the unpropitious weak areas.
