Background & Objective: Chickpea is rich in nutrients and compared to animal protein, it acts as a cheap source of protein, with good quality, so it can be useful for food security in developing countries. 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. The purpose of this study is to screen the response of drought tolerance after the germination stage in different cultivars of chickpea and to select drought tolerant cultivars, to identify the most desirable and stable drought tolerant indicators and to know the relationships between them in order to it was designed and implemented to be used in future improvement programs to achieve higher yield in the level unit.
Materials & Methods: To carry out this research, seven cultivars of chickpeas, including Yadegar, Adel, Ana, Kasra, Mansour, Kaviyan and Arman cultivars, were prepared in the crop year of 2023 with a randomized complete block design with three replications in the educational-research farm of Payame Noor University cultivated in Asadabad (Hamedan). 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.
Results: The results 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, the indices, stress tolerance index, tolerance index, yield index, tolerance index to Changed stress under stress conditions, stress tolerance rating index, mean productivity index, harmonic average index and geometric mean productivity index were found to be appropriate. These indices were able to identify drought-tolerant cultivars with suitable and acceptable yield 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 Yadegar, Kasra, and Adel, respectively.
Conclusion: Based on the results of all statistical analyses, such as analysis of variance, comparison of averages, correlation analysis of indicators, bi-plot analysis and cluster analysis, Yadegar, Kasra, and Adel cultivars, respectively had the highest yield per unit area. The use of planting density and different planting dates in the coming years to achieve more valuable results is highly recommended.
