To observe the stimulating effect of low dose ${gamma}$ radiation on the dormancy breaking and growth, microtubers induced in vitro of two potato (Solanum tuberosum L. cv. Dejima and cv. Superior) cultivars with different storage duration were irradiated with ${gamma}$ radiation at the dose of $0.5{sim}30$ Gy. Sprouting rate, growth and tuber yield of ¡®Dejima¡¯ microtuber were increased by ${gamma}$ radiation in the range of $2{sim}16$ Gy. In the microtuber of ¡®Superior¡¯, the sprouting rate was promoted by 2 Gy and 4 Gy irradiation, and the growth and tuber yield by 0.5 Gy and 4 Gy irradiation. There were not that much difference in chlorophyll content of potato plantlet by the low dose ${gamma}$ irradiation. These results suggested that low dose ${gamma}$ radiation stimulated the dormancy breaking and potato growth.
