Objectives: This research was conducted in order to evaluate the reaction of different barley genotypes and to understand better the genotype × environment interaction effect in different areas of the country's cold climate, and to select stable genotypes. Materials and Methods: Four barley genotypes, including Jalgah, Mehtab, Bahman, CB-96-10, along with four imported genotypes in five stations of Karaj, Zanjan, Jalgarokh, Ardabil, and Miandoab in the form of complete randomized block design with three replications in two consecutive years of evaluation became. Results: In Eberhart and Russell method, G1, G4, and G6 genotypes; in parametric methods G1, G4, G6, and to some extent G7 genotypes and; in nonparametric methods G1, G4, and G6 genotypes were identified as stable genotypes. According to the comparison of average performance, sustainability criteria and agricultural characteristics and general compatibility using AMMI analysis, G6, G1, and G7 genotypes were recognized as the most suitable and most compatible genotypes, respectively and can be considered as climate compatible cultivars in all cold regions of the country. Genotypes G2, and G3 are also considered varieties with private compatibility. Conclusion: According to the results, G6, and G1 genotypes can be considered as the most compatible genotypes in all cold regions of the country, and G2, and G3 genotypes can also be considered as genotypes with high private compatibility in high potential regions.
