Characterization of Some Macromutations Induced by Single and Combination Treatments of Gamma Rays, EMS and SA in Urdbean (Vigna mungo L. Hepper)
Abstract
Two cultivars of urdbean (Vigna mungo L. Hepper), namely, PDUI and T9 were treated with single and combination doses/concentrations of gamma rays, ethyl methane sulphonate (EMS) and sodium azide (SA). Number of various types of morphological macromutations were induced in M2 generation. Of these, thirteen mutants from PDUI and twelve 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.
