Abstract:
Soybean JS-335 was treated with 200 Gy, 250 Gy and 300 Gy doses of gamma rays to study the effect of gamma radiation on germination, 100 seed weight and grain yield in M₂ generation. The experiment was conducted in the farm of Samarth Agriculture College D. Raja Dist. Buldana during kharif and rabi 2017-19. Gamma rays reduced germination in M₁ and increased in M₂ generation_. 100 seed weight decreased in all treatments highest mean value was in 200 Gy (12.12 gm) and lowest in 300 Gy (10.94 gm) as compared to control (12.98 gm). Plant produced the most grain yield in T₂ (6.97 gm) and the least in T₁ (5.97 gm). The variability showed the coefficient of variation increased in all treatment. In M₂ generation germination and yield per plant increased significantly in all treatments and 100 seed weight significantly decreased in all treatments as compared to control.
