Salinity stress is a serious threat of plant growth and production all over the world. Salinity in comparison with other stresses, limits the plant growth in a wider scale. So there is a possibility of cultivar diversity use in a desirable traits selection under stress conditions. Therefore, to identify selection indices in hull-less barley under salinity stress. This experiment was conducted. This experiment was investigated in 2004-2005 in green house at Golestan agricultural research center. The design of the experiment was random complete block design (RCBD) with 4 replications in a large plat (5×4×1.8m3). 30 centimeters between row on a single line 1.5m.For irrigation using level of salinity 160 mM NaCl. results of variance analysis showed that traits of relative water content (RWC), height, tillage in shrub, number of fertile tiller, length of spike, number of grain in spike, as significant different for traits and most of them decreased under stress conditions. But the hieghst decrease was observed in grain yield, biologic yield, plant height and leaf area index.
