Abstract: The present study was conducted to induce both phenotypic and genotypic variability in variety RBL-50 by ethyl methane sulphonate and gamma rays. Both the macro- and micro-mutations were studied in M2 generation to estimate the frequency of mutation induced and effectiveness of mutagenic treated populations. Wide spectrum and frequency of chlorophyll mutations was observed in M2 generation. Among different types of chlorophyll mutations, chlorina occurred at a higher frequency whereas albina types appeared in the least frequency. The total macro- mutation frequency was higher in gamma rays. The 0.2% EMS treatment was most effective in inducing mutation among the EMS treatments whereas 250Gy among the gamma rays treatments. However, higher dose treatments induced more of genetic variability in M2 in respect of most of the quantitative traits. The results indicate scope of rice bean genetic improvement through mutation breeding programme for yield attributing traits.
