Effect of 250Gy, 300Gy, 350Gy and 400Gy gamma rays on Badsabhog, popular non-basmati aromatic landraces of West Bengal was studied in M1 generation under field condition. In general, plant height, number of total tillers, effective tillers plant-1, panicle exertion, spikelet number panicle-1, filled grains panicles-1, productive tiller hill-1, spikelet fertility (%), and grain yield plant-1 decreased with increase in dose at variable rate due to negative effect of mutation. Total tiller hill-1, Primary branch panicle-1 and Secondary branches panicle-1 were increased in all the irradiated population over control, which might be due to stimulatory effect of mutagen. The results indicated the differential sensitivity of the genotypes and characters to radiation treatment. The overall results indicated that spikelet fertility percentage (%) was more sensitive to gamma irradiation as compared to other yield attributing characters in non-basmati aromatic rice.
