The inheritance of resistance to cercospora leaf spot (CLS) in mungbean was studied in eight interspecific crosses involving four resistant (Pant U 30, PDU 1, BHU U 1 and DPU 88-31) and three susceptible (K 851, China Mung and Kopergaon) genotypes of urdbean and mungbean. The infector row technique as well as artificial inoculation with Cercospora canescens culture was applied to screen the material. Resistance to CLS was dominant over susceptibility in the F, generation of all the eight crosses. Observations on disease scoring of F, and F, generations indicated a single dominant gene governing resistance against CLS in each of the three crosses studied.
