Abstract: Food legumes are the wonderful crops and cheapest source of protein in the daily diets of urban and rural masses throughout the world. In these days, its production is almost motionless causing declining per capita availability and high cost of the food legumes made serious threats for food and nutritional security in Nepal. In addition to the inherent low yield potential of many food legumes, there are several diseases, insects and pests and drought. In cowpea drought resistance is reported to be controlled by a single dominant gene. The promising drought tolerant varieties of cowpea were IT98K-1399, IT98K-131-2, IT97K-568-19 and IT98K-452-1. Among the pigeonpea hybrids tested, ICPH 8 and ICPH9 were the most drought tolerant. Likely the line ICPL88039 showed greater drought tolerance. Drought tolerance lentil cultivars were ILL-7979, ILL-10960, ILL -10973, ILL-10897, ILL-10821, ILL-10826, and ILL-10835. In fact, drought tolerance on the whole plant basis makes it a complex trait and difficult to manipulate by plant breeders. There is an urgent need for exploration of the plant genetic resources with attributes related to drought resistance in different crop plants. Attention should be concentrated on better understanding of genetic basis of drought resistance through antisense RNA technique. National and International research institutes are being attempted to address the issues by developing extra early varieties combined with resistance to major diseases, insects-pests and tolerant to drought so that some of these legumes may fit in the existing niches in cereal based systems and perform well even in the drought-prone and marginal environments. This paper briefly reviews the challenges, progress and future strategies made in breeding for drought tolerance in major food legumes.
