Induced mutagenesis was employed to create genetic variation for various quantitative traits viz., fertile
branches per plant, pods per plant and grain yield per plant in M2
and M3
generations of lentil (Lens
culinaris Medik) following mutagenesis with EMS, HZ and SA. The mean number of fertile branches, number of pods and grain yield per plant increased significantly after mutagenic treatments in M3 generation. Analysis of variance revealed significant inter-population variability for the observed quantitative phenotypic traits in both the M2 and M3 generations. The estimates of genotypic coefficient of variation, heritability and genetic advance for yield and yield components were recorded higher in mutated population. Current study revealed that all the three chemical mutagens were most effective at 0.3% concentration in inducing desirable variations in quantitative yield traits, where mutagenic potency of EMS was found relatively higher compared to HZ and SA. Higher values of heritability and genetic advance coupled with high genotypic coefficient of variation for yield and yield attributes confirmed the possibilities of selecting more promising lentil lines with high yield potential in ensuing generations.
