Abstract

The use of stress tolerance indexes is one of the most promising methods for selection of stress tolerant genotypes among researchers. In this research, 11 bread wheat cultivars were evaluated in a randomized complete block design with three replications under two non-stress and drought stress conditions at research field of Faculty of Agriculture, Lorestan University, Khorramabad, Iran, with warm and dry climate, in 2016-2017 crop season, and different stress tolerance indices were used to evaluate drought tolerance of the studied cultivars. Also, Coefficient of determination (R2, square of the correlation coefficient) between the indices and Grain yield under two non-stress and drought stress conditions was used to determine the best indices and R-square confidence intervals of the tolerance indices related to Grain yield under non-stress and drought stress conditions were estimated using bootstrap method. The results showed that the modified stress tolerance index under non-stress conditions (K1STI), geometric mean productivity (GMP) and mean productivity (MP) were the specific indices for non-stress conditions and the modified stress tolerance index under drought stress conditions (K2STI) and drought index (DI) were the specific indices for drought stress conditions. Harmonic mean (HM) index had also a relatively stable correlation with Grain yield under both non-stress (Yp) and drought stress (Ys) conditions. Finally, according to all specific and general indices, Aftab was the best cultivar under non-stress conditions and Pougari was identified as the most tolerant cultivar for drought stress conditions.
