Abstract

Two improved cultivats of urdbean (Vigna mungo L. Hepper), namely, PDUI and T9 were treated with single and combination doses/concentrations of gammarays, ethyl methane sulphonate (EMS) and sodiumazide (SA). A number of various types of morphological macromutations were induced in M2 generation. Out of these, fourteen mutants from PDUI and thirteen 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.
