Abstract:

An experiment was conducted to generate a broad genetic variability through induced mutation using physical and chemical mutagens. Three doses each of gamma rays (20, 40 and 60kR), ethyl methane sulphonate (0.2, 0.4 and 0.6%), nitrosoguanidine (0.005, 0.010, and 0.015%), maleic hydrazide (0.01, 0.02 and 0.03%) and their combinations were administered to the seed of two greengram varieties, Sujata and OBGG-52. In M2 generation most treatment populations exhibited a reduction in population mean and increased in population variance for pods/plant, seeds/pod, 100 seed weight, yield/plant and the magnitude of such changes varied with mutagens, their doses and genotypes. A greater shift in mean and variance was observed in treatments with higher doses. The negative shift of mean was more pronounced in MH and its combined treatments in both varieties. In general, most of the mutagen treated populations showed a wider range of variation than the parent varieties and the variation was in both directions. The higher values of heritability and genetic advance with a high genotypic coefficient of variation for most of the yield attributing traits confirmed that selection in M2 populations would be effective in bringing the improvement in yield/plant and its direct components like pods/plant, seeds/pod, and 100 seed weight.
