Abstract:
This study was conducted to assess the most important drought tolerance selection indices in Chickpea: Drought resistance index (DTI), Golden mean (GM), Harmonic mean of yield (HM), Mean productivity (MP), Relative drought index (RDI), Sensitivity drought index (SDI), Stress susceptibility index (SSI), Stress Susceptibility percentage index (SSPI), Stress tolerance index (STI), Stress tolerance (TOL), Yield Index (YI), Yield Stability Index (YSI) n order to screen drought-tolerant Chickpea genotypes.The trials were conducted at the Qarhata Research Station of the General commission for Scientific Agricultural Research (GCSAR) during the agricultural season 2017/2018 to evaluate the response of 12 genotypes of chickpea to water stress, the experiment was laid out according to randomized complete block design with three replications. Results showed that drought indices (DTE, GMP,RDI) had the highest significant positive correlation with seed yield under stressed condition, and both (SSI, and SDI( could be applied for screening of chickpea genotypes for drought stress tolerance. The genotypes FLIP 05-044 and Ghab5 were the best drought tolerant, so they are recommended to enter in breeding programs for drought tolerance The genotypes FLIP 05-044 Can be tested in advanced tests for variety utilization.
Keywords: chickpea, drought indices, correlations analysis, seed yield.
