Induced physical and chemical mutagenic studies in m1 generation of mungbean [vigna radiata(l.)wilczek]

The Mungbean [Vigna radiata (L.) Welczek] is one of the most important pulse grain crops of the Indian subcontinent having a high amount of protein. In the present study seeds of two varieties of mungbean were with gamma rays (100Gy, 200 Gy, 300Gy and 400Gy), EMS, and SA (0.1%, 0.2%, 0.3%, and 0.4%) respectively. In the M1 generation, it was noted that physical mutagen gamma rays showed a comparatively higher percentage of germination than chemical mutagens EMS and SA. It also showed a higher rate of survival and plant fertility. The rate of germination in gamma-ray treated seeds AKM- 8802 ranged from 82 to 93.65%, and in the case of AKM-4 it was 87.30 to 88.88%, which was very close to respective controls. However, the trends observed that increase in the dose or concentration of mutagen there is a decrease in the rate of germination, rate of plant survival, and rate of plant fertility in all mutagens. These mutagens also showed a significant effect on the sterility of plants and thereby affecting fertility of the plants.
