Wilt (Fusarium oxysporum f.sp. ricini), root rot (Macrophomina phaseolina) and gray rot (Botrytis ricini) are devastating diseases of castor (Ricinus communis) in India . No controlling measures are fully effective. None of the existing cultivars is resistant to these diseases. Hence, in this study, intensive screening of indigenous castor germplasm against wilt, root rot and gray rot was carried out. This screening identified several sources of resistance, which are being used extensively in castor improvement programmes
