Abstract

Two improved cultivars of urdbean (Vigna mungo L. Hepper), namely, PDU1 and T9 were treated with single and combination doses/concentration of gamma rays, ethyl methane sulphonate, (EMS) and sodium azide (SA). A number of various types of morphological macromutations were induced in M2 generation. Out of these, 14 mutants from PDU 1 and 13 from T9 were identified as true breeding for plant morphology, pod and seed characters and early maturity in M3 generation. Many macromutants showed significant improvement in yield and other yield components as compared to their parents.
