The study of the interaction of genotype and environment adaptability and yield stability of promising barley lines is one of the major issues in the race which is very important in The development of improved cultivars. In order to achieve these goals promising lines should be cultivated in different climatic conditions and evaluated. The test was done to determine the adaptability and yield stability of barley lines with 16 lines with 2 control for two years and two locations in a randomized complete block design with three replications. Combined analysis showed a significant difference at the 1% level. This means that the lines were in the same behavior and this proves Genotypeenvironment interaction effects in this case. Univariate parametric stability methods showed that Lines 1 and 13, with good stability and lines 5, 10, 12 and 14 were lines of Group C (low and stable product, respectively).
