Considering the limitation of water needed for irrigation, especially the issue of water shortage in the future, and considering the decrease in average rainfall in recent years, it will be inevitable to conduct applied research in the field of drought. For this research, seven cultivars of chickpea were prepared and cultivated in the research training farm of Payame Noor University of Asadabad in the year of 2023 with a randomized complete block design with three replications. The above-mentioned experiment was carried out in two humidity conditions, the condition without irrigation and the condition with supplementary irrigation in the late stage of the germination period. The potential of drought tolerance indices was used in this research. The findings of the present study showed that under normal cultivation conditions, the growth and development of the plant increased significantly compared to the conditions under drought stress, and according to the results obtained in this study, STI, TOL, YI, K2STI, STS, MP, HAM and GMP were found suitable. These indices were able to identify drought-tolerant cultivars with suitable and acceptable performance in both environmental conditions (supplementary irrigation conditions and drought stress conditions). The cultivars that were able to be selected in both environmental conditions by the aforementioned indicators included cultivars number Yadegar, Kasra and Adel, respectively.
