In order to assessment of drought-tolerant barley genotypes, 15 genotypes were evaluated in a randomized complete block design with two replications in stress and non-stress conditions, in the College of Agriculture and Natural Resources, Razi University of Kermanshah. To evaluate the tolerance of the genotypes based on yield, under stress and non-stress conditions, some drought resistance indices were used such as: stress susceptibility index, tolerance index, mean productivity, geometric mean productivity and stress tolerance index. There was a significant difference among genotypes regarding the indices and yield in both conditions. The results showed that indices GMP, MP and STI had the highest correlation with yield in both conditions and can be considered appropriate criteria for selection of superior genotypes. Using biplot curve obtained from the two first principal components it was shown that genotype-9 is the best considering drought tolerance.
