Abstract

In order to achieve genotypes with yield stability, 18 selected barley lines with two controls (EC82-6 and EDBYT82-9 for ABYT-DC1). Experiments were conducted for one year, using Randomized Complete Block Design with three replications in five stations of cold region including: Karaj, Mashhad, Miandoab, Tabriz and Hamedan during the cropping season 2014-2015. Simple and combined analyses of variance and multivariate analyses of data for all the traits and index parameters were performed. The results showed that there were significant differences among locations, genotypes and genotype × location interactions in both experiments under different irrigation regimes except for the effect of genotypes in the second experiment. Using all aspects of the analyses, the lines numbers: 13,9,18 and 7 showed the highest yield, and stability for ABYT-DC1 respectively. In overall, based on mean of grain yield, stability parameters and important traits such as early maturity, resistance to diseases,
