چکیده

genetic× environment interaction for genetic, plant breeder and animal breeding is very important. insight of g×e helps to plant breeders for genotypes evaluating precisely until select the best genotypes and release the stable genotypes for general and special environments. present study in order to achievement to high yield and yield stable in the different years, was done on the 20 advance barley lines with mahoor and khorram cultivars as checks in the 2010-2013 growing season at the 4 stations namely; gachsaran, moghan, gonbad and lorestan. each genotype was planted in 6 rows with 7.03 meters length, 17.5 cm spacing from each other by cereal seed planter device based on rcbd design with 4 replications. during growing season recording data was done from agronomic and morpho- physiological characters. combine analysis of variance was accomplished and yield stability was surveyed by parametric, nonparametric and multivariate analysis. combine analysis of variance was done by general linear models (glm) and mix models so that all of effects such as environment, genotype and genotype* environment interaction effects were significant at probability levels (p
