| description | To identify drought tolerant genotypes from 40 doubled haploid and 5 barley cultivars an experiment in a randomized complete block design with three replications was conducted both at normal irrigation and water deficit stress conditions at the Agricultural Research Station of West Azarbayjan, at Miyandoab during 1390-91 crop years. A significant difference was observed among the genotypes concering grain yield, which indicates a high genetic diversity for this trait among genotypes under study. Genotypes No. 35, 24, 21 and 3 were highest yielders in both irrigation conditions. In this study, during tolerance of genotypes under both stress and normal irrigation conditions, were evaluated by using mean productivity (MP), tolerance (TOL), geometric mean productivity (GMP), stress susceptibility (SSI), and stress tolerance (STI) indices. According SSI and TOL indices genotypes 13, 16, 1, 19, 8 and 5 were identified as tolerant genotypes to water stress. Genotypes 3, 24 and 35 were found to have highest STI, MP and GMP indices. Correlation coefficients indicated that STI, MP and GMP were the best indices to select barley tolerant genotypes to water deficit stress in this study. It was also revealed that genotypes 3, 21, 24 and 35 which were highest yielders under normal irrigation and did have the least reduction in their yield under deficit irrigation. Thus, they can be recommended to the experimental site as the top producers. |
