Abstract

In order to select BARLEY genotypes tolerance to DROUGHT STRESS, an experiment in split plot arranged based on completely randomized blocks design with three replications in the research center of agriculture of Southern Khorasan in 2013-2014 crop years. DROUGHT STRESS in 2 levels consists of control (Complete irrigation) and stopping irrigation at the 50% of heading stage, and BARLEY genotypes include of 20 genotypes were selected as treatments of experiment. The results indicated that the genotype numbers 2, 3, 5, 9, 12 and 13, using stress tolerant index (STI), numbers 3, 5 and 18 according to geometric mean productivity (GMP), mean productivity index (MP) and stress susceptibility index (SSI) and numbers 2, 3, 12 and 13 based on tolerance index (TOL) were determined as the most tolerant genotypes. 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 condition and minimum YIELD reduction under DROUGHT STRESS, the numbers 3 and 5 introduced as the most tolerant BARLEY genotypes.
