In order to evaluate the economical and biological performance of hulless barley genotypes in potential and salinity stress conditions, This study was carried out during (2000-2001) crop year. Fifteen hulless barley genotypes and hulled barley (Hordeum vulgare var Turkman) were evaluated in a simple lattice statistical design with two replications at Gonbad Research Station (Potential Condition) and Aghgalla (Salinity stress condition). Biological and economical performance, harvest index (HI), yield components, plant height and the other agronomic triats were determined. For evaluating of genotypes tolerant to salinity, Stress Tolerance Index (STI) calculated in each genotype separately. Data analysis of variance showed significantly difference (P0.01)Within genotypes in the traits of economical performance , Plant height, number spikes per square meter and kernels per spike. Also,. There were significantly at difference 5% level in the triats of dry matter production before heading stage and 1000-Grain weight. Evaluated of stress tolerance index showed that genotypes number 9, 13, 3, 14, 6, 5, 16 were STI 0.69, 0.64, 0.41, 0.40, 0.38, 0.36 and 0.35, respectively. These genotypes selected for planting at next year.
