Abstract:
Seeds of L. sativus cv. NLK-73 were exposed at three different doses of gamma radiation (250Gy, 300Gy, and 350 Gy) to study effect of gamma radiation on germination. 100 seed weight and grain yield per plant in M₂ generation. The experiment was conducted at Research Farm, Shankar Nagar, Botany section, College of Agriculture, Nagpur during rabi 2020-2021. Gamma rays reduced germination in M₁ and increased in M₂ generation. 100 seed weight decreased in all treatments highest mean value was in 350Gy (6.91g) and lowest in 250Gy (6.30g) as compared to control (4.26g). Plant produced the highest grain yield at 350 GY (24.56g) and the lowest at 300 GY (20.20g). The variability showed the coefficient of variation (increased or decreased?) in all treatments. 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.
