ABSTRACT
An experiment was conducted during 2012-13 to induce polygenic variability for yield and its components in groundnut (Arachis hypogaea L.). Groundnut genotype CTMG-6-1 were treated with gamma radiation (20, 30 and 40 kR) and ethyl methane sulphonate (EMS- 40mM and 60mM). The mutagenized population showed significantly higher variability in M2 generation.The various macromutations viz., earliness, height, high yielding and late maturity were identified and isolated in M2 generation. EMS 40 mM and 60 mM were found more effective for including range of desirable mutations in groundnut under present investigation. Early maturing mutants (111 days) were found among the population obtained by treatment of 60 mM EMS over the check. One of the most interesting features of mutant was the significant contributing to higher yield over check. The mutant HY 3 isolated from 40 mM EMS treatment was recorded highest seed yield per plant (30.21 g). On the basis of plant height, two tall mutants were isolated from 60 mM (EMS) treated M2 population. For late maturity 40 mM (EMS) treated M2 population shown one mutant which matured late than the control by 4-5 days. The usefulness of the mutants identified in a groundnut breeding program is discussed. These promising mutants can be further utilized in recombination breeding with other mutants or cultivars to derive distinct lines with improved agronomic traits.
