The improvement for genetic yield potential under dryland farming systems is essential in all the field crops in general and particularly grain legumes, because globally more than 80% area of grain legumes is under rainfed agro-eco system. Generally more than 3-4 trait combinations, viz. high genetic yield potential, resistance against abiotic and biotic stresses, and adaptability, are essential to get good harvest under drylands. Keeping this in consideration genetically diverse sources of chickpea were comprehensively utilized adopting different breeding approaches. Crosses were first made utilizing germplasm from different geographical regions. These were then crossed with each other for the development of multiple crosses, creating genetically divergent gene pools in the segregating material. Fz onward, the segregating generations were screened under moisture stress environment in multiple sick plots. Single plant observations for various quantitative traits at vegetative, reproductive and maturity stages were recorded. Finally, single plant progenies were evaluated for yield performance under multiple sick plots. The superior lines were promoted for all India multilocation yield testing and for evaluation of agronomic performance. The genotypes like BG 1105 , 1106 , 107 , 1108 and 1109 showed significantly superior performance in relation to seed yield, resistance against drought and Fusarium wilt in northern, central and southern India. Such performance has been observed first time in Indian Kabuli chickpea cultivars because of the combination of desirable genes from divergent sources. Therefore, it is concluded that through utilization of genetically diverse genes the superior genotypes can be developed in chickpea and other grain legumes for stable and profitable cultivation under moisture stress environments.
