Abstract

To study the effects of end season DROUGHT STRESS on YIELD and YIELD components of 20 promising genotypes of BARLEY, an experiment was conducted in a split plot in the basis of randomized complete blocks design with three replications in agricultural research center of Southern Khorasan during 2008-2009 crop years. DROUGHT STRESS consisted of 2 irrigation levels (complete irrigation and withholding irrigation at the 50% of heading stage) and 20 BARLEY genotypes were treatments. The results showed that by using stress susceptibility index (SSI) No. 2, 3, 7, 9, 10 and 15 by using stress tolerant index (STI) and geometric mean productivity (GMP) No. 5, 8, 18 and 20, by application mean productivity index (MP) No. 8, 18 and 20 and by using tolerance index (TOL) No. 2, 3, 7, 9, and 10 as the most tolerant genotypes were introduced. Summarized results of correlation between seed YIELD and stress evaluation indices showed that MP, GMP and STI are the best indices for selection and introducing drought tolerant genotypes among BARLEY genotypes. With review of all indices and given that the best genotypes are individuals with high YIELD under normal conditions and minimum YIELD reduction under DROUGHT STRESS, No. 18 and 20 introduced as the most tolerant BARLEY genotypes.
