Two improved cultivars of urdbean namely PU-19 and PU-35 were treated with single and combination dose/concentration of gamma rays, ethyl methane sulphonate (EMS) and diethyl sulphate (dES). A number of plant mutants viz. dwarf type, spreading type, umbel inflorescence, long inflorescence axis, broad leaved sterile vine type, broad leaved fertile vine type, lanceolate leaf sterile vine type, hastate leaf fertile vine type, hastate leaf sterile erect type and anthocyanin pigmentation were obtained in M2 generation of both varieties by various mutagenic treatments.
