Abstarct: 95% of chickpea cultivated area in the country is rainfed and drought stress is the most important factor of reducing the yield per unit area of chickpea fields. In order to evaluate the tolerance of some genotypes to drought stress experimental was carried out as factorial randomized complete block design with three replications in the researching- educational field of Hamedan Jihad-Agricultural Education Center in 2010.Factor A included eleven chickpea genotypes, and factor B included two moisture regimes (irrigated and drought). The results indicated highly significant effect of factors and its interaction effectes on plant height, stem dry weight, leaf dry weight, leaf area index, number of branches per plant, number of pods per plant, seed number per plant, 100 grains weight and yield. The results showed highly significant differences in genotypes baxse on first pod height from ground and number of pods per plant and the moisture regime was highly significant in these two traits. Interaction genotype × irrigation regime on first pod height from ground and number of seeds per pod was not significant. baxsed on yield in non-stress conditions (Yp) and stress (Ys), drought tolerance quantitative indicators such as: mean productivity (MP), tolerance (TOL), geometric mean productivity (GMP), harmonic mean (HARM), sensitivity to stress (SSI), stress tolerance (STI), yield rate loss (Yr), yield stability index (YSI) and yield index (YI) were calculated. In the evaluation of Drought tolerance indicators index, average productivity (MP), showed the highest positive correlation with the yield stress and non stress conditions. Pirooz genotype was indentified as drought tolerant.
