Studies on Induced Physical and Chemical Mutagenesis in Groundnut (Arachis hypogia)

Full Text PDF


Mutation breeding has been widely used for the improvement of plant characters in various crops. It is a powerful and effective tool in the hands of plant breeders. In any mutation breeding program, selection of an effective and efficient mutagen is very essential to produce high frequency of desirable mutation. Groundnut (Arachis hypogia) var. VRI-2. was treated with different concentration of physical and chemical mutagen namely gamma rays 10, 20, 30, 40, 50 and 60 KR and Ethyl methane sulphonate (EMS). For inducing mutation various concentration of EMS such as 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 % for six hours were applied to 200 seed sample of each concentration and one respective control. The LD50 value was observed in 50% of gamma rays and 0.5 % of EMS. The morphological and yield characters were significantly reduced seed germination, seedling survival, days to first flower, plant height, number of leaves per plant, number of grains per plant, grain length and breath, 100 grains weight, grain yield per plant, fresh and dry weight per plant. The increasing doses/concentration of gamma rays and EMS decreased in phenotypic and yield characters in M1generation. The mutagenized populations showed significantly higher variability in the M2 generation. Mutant lines showing higher yield per plant than the respective parents and checks were isolated in M2 and subsequent generation were significantly more pod yield and yield components than the untreated plants.
