abstract: Drought decreases the yield of dryland crops over vast areas of the world. The incidence of drought is generally higher in the semi-arid regions which constitute 36% of the total land area according to raheja (1966). Much of the remaining area undergoes temporary drought during the crop season. Since ICRISAT's objective is to breed the crops with adaptation to the semi-arid tropics it is a corollary that we should breed for drought resistance in ICRISAT mandate crops. It is generally well recognized that on a world wide basis the major factors limiting groundnut produciton are foliar diseases, drought and nutrient stress(Gibbons, 1981). In the SADCC region 75% of the area us semi-arid and characterized by low, unreliable and/or poorly distributed rainfall. Mid-season drought are of common occurrence and the need for breeding drought resistant groundnut cultivars for this region has been stressed by several researchers (Nigam & Bock, 1984; Chiteka, 1984; and Doto, 1984). Also the SADCC Food Security Consultative Technical Committee for Agricultural Research has emphasized the need for short duration drought resistant varieties for this region (Manda, 1984). In addition to causing substantial yield reduction drought can result in poor seed grades(Davidson et Al, 1983; Stansell et Al, 1976), decreased subsequent germination (Pallas at Al,1977). The present paper deals with some aspects of drought resistance and the progress that has been made at ICRISAT in groundnut drought research
