This study was performed to assess several indices for identifying genotypes at early growth stage with thebest performance in salinity conditions. In order to evaluate the biomass production of barley genotypes indifferent levels of salt conditions, an experiment was conducted as factorial arrangement with a completelyrandomized design with 3 replications. The effect of salinity treatments was studied through an analysis of thedry matter production, yielding results that show significant differences among genotypes. The majority ofused tolerance indices indicated that ESBYTM8910, 4 Shori and MBS8715 were the best barley genotypesshowing the highest stress resistance for the greatest NaCl concentration. Based on used stability parametersthe genotypes MBS8712 and Jo torsh were the most phenotypically stable. Result of cluster analysis revealedthat tolerant genotypes showed the least stability based on mostly of stability parameters. In general, resultsshowed the WB7910, ESBYTM8910 and MBS8715 genotypes appeared better than others across the salinitylevels.
