Abstract:

Seed treatment with gamma rays, EMS, NG and their combinations in two mungbean genotypes, BKG-1 and OUM 11-5, significantly reduced germination, seedling growth including fresh weight and dry weight, pollen fertility, seed fertility and survival at maturity in M1 over the parents. The biological damage in M1 generation showed a dose dependent linear relationship. NG in both single and combination treatments resulted in more pronounced biological damage than other treatments. Five types of chlorophyll mutations (albina, xantha, chlorina, viridis and sectorial) and nineteen different morphological macro-mutations were recorded in M2. Population variance in M2 increased in each mutagenic treatment of both the varieties over the respective control for six quantitative traits including seed yield. The M1 parameters e.g., germination, survival and seedling characters showed negative correlation with M2 macro-mutation frequencies and M2 population variance (micro-mutation), while pollen and seed sterility in M1 showed positive association with M2 macro-mutation frequencies and M2 population variance. Such a relationship may be useful for effective selection of mutagenic populations at even M1 generation to achieve wider genetic variability in M2 and later generations.
