Analysing the salt tolerance indexes (mean productivity [MP], geometric MP [GMP], stress tolerance index [STI], stress stability index [SSI], tolerance index [TOL], yield index [YI], and yield stability index [YSI]) on productivity on salt stress are one of the best ways to identify naturally existing variant in the crop accessions. Eight USDA barley accessions (Kindred, Morex, ELS 6302-5, NB 5, MOR 7 / 5, seco, 334 and 1532) were investigated the effect of salt stress at 10 dSm−1 on yield parameter compared to non-stressed crops. On grain maturity dry weight, number of leaves, number of tillers, total plant height, number of sterile, and fertile tillers, and number of grains in each plant were recorded. In the leaf and leaf sheath, mineral ions such as sodium (Na+) and potassium (K+) were estimated using inductively coupled plasma–optical emission spectroscopy. The stem and leaf parts were explored for their calorific value using a bomb calorimeter. Yield under stress showed positive correlations with GMP and STI than TOL, SSI, and YSI based on principal component analysis and cluster analysis. Based on the analysis Kindred, ELS 6302-5, NB 5, and 334 accessions show salt stress tolerance. The salt tolerance accessions are naturally existing high-yielding ones. Hence, that can be recommended for cultivation on the farmland affected by salinity.
