Mutagenesis for Oligogenic Traits with Gamma rays and EMSin Groundnut(Arachishypogaea L.)

Abstract

Induced qualitative mutation in TAG-24 groundnut cultivar consisted of chlorophyll and viable mutants. The combination treatments exhibits wide spectrum and frequency on both M1 family and M2 plant basis for both. Increased in doses and concentrations of mutagens showed increased in spectrum and frequency. Chlorophyll mutants viz. albino, albo-viridis, xantha, xantha- viridis and viridis and viable mutants viz; plant type, leaf, growth habit, flowering, pod, kernel and economic mutation were observed. Desirable mutants like bold poded, early maturing, high yielding were also isolated.
