Effect of low dose gamma radiation on the growth of groundnut (Arachis hypognea L.) were investigated with respect to germination rate, seedling development and yield. Seeds of ¡°Palpal¡± cultivar were irradiated with 0.5~20 Gy of ${gamma}$ radiation in order to determine the hermetic effect of low dose radiation. The germination rate of ${gamma}$-ray irradiation group was lower than that of the control but the seedling height of groundnut grown from seeds irradiated with low dose ${gamma}$-ray was slightly higher than that of the control. The number of pod and kernels, and the seed yield increased by 27%, 17% and 19 %, respectively, in the 12.0 Gy irradiation group compared to that in the control group. The 100 seed weight was 87.2 g in the 4.0 Gy irradiation group, which was 11% heavier than 78.3 g in the control group. Low dose radiation showed an enhancement effects on the growth and yield components of groundnut.
