Abstract:
Gamma rays and EMS treated seeds of three soybean genotypes (TAMS 38, AMS 1001 and RSC 10-46) was evaluated for germination, seedling height and survival percentage during M₁ generation. Mutagenic treatment with four doses of gamma rays (150 Gy, 200 Gy, 250 Gy and 300 Gy) and three concentration of ethyl methane sulphonate (0.1%, 0.15% and 0.2%) showed reduced germination as compared to corresponding control. Decrease in seedling height and survival percentage with increase in dose / concentration of mutagen was also observed in all three soybean genotypes. Maximum reduction in three parameters was noticed at 300 Gy gamma rays treatment except seedling height in RSC 10-46 whereas as regards to soybean genotypes, AMS 1001 found more sensitive to mutagens as compared to TAMS 38 and RSC 10-46.
