Abstract

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