In order to evaluate indicators of drought tolerance and identification of drought tolerant genotypes in bread wheat, 96 F3 families (resulting from cross Roshan and Kavir), parents, F1 and F2 progenies were cultivated based on lattice design under drought stress and normal conditions in field of Shahid Bahonar University of Kerman in growing season of 2012-2013. The results of ANOVA showed significant difference between genotypes for grain yield, normal and drought stress condition. Genotype 92 had the highest grain yield under drought stress condition, and genotype 13 had the highest grain yield under normal condition. Genotype 59 was recognized as the most drought tolerance genotype based on B and TOL, genotype 92 was recognized as the most drought tolerance genotype based on HARM, GMP, STI and MP, and genotype 52 was recognized as the most drought tolerance genotype based on YS and SSI. Finally, stress tolerance score (STS) was calculated. 6.1 percent of F3 family had higher STS than the average of parents. Genotypes 92 and 70 appeared to be the most drought tolerant and sensitive genotypes, respectively.
