Online Published on 12 August, 2024. Abstract The M0 seeds of mungbean variety DGGV 2 treated with different doses of ethyl methane sulphonate (EMS) at 0.1%, 0.2% and 0.3% concentrations were assessed for Mungbean Yellow Mosaic Virus (MYMV) in M2 generation during summer 2023 at University of Agricultural Sciences, Dharwad. Considering the yield superiority over check (Mean + 2 Standard Deviation) and highly resistant response to MYMV disease, out of 962 M2 plants 17 superior M2 plants were identified. The seed yield plant-1 in these identified mutants ranged from 21.9 to 32.0 g which is higher compared to the average yield of check DGGV 2 (11.7 g) during that season. Also, the other yield contributing traits such as number of productive branches, number of cluster plant-1, number of pods cluster-1, and number of pods plant-1 were observed to be higher in these mutants in comparison to check variety.
