Pepper (Capsicum annuum L. cv. Jokwang and cv. Johong) seeds were irradiated with the doses of 0-50 Gy to investigate the effect of the low dose ${gamma}$-radiation on the early growth and resistance to subsequent high dose of radiation. Following effect was observed in Johong cultivar but not in Jokwang cultivar Germination and early growth rate of Johong cultivar were noticeably increased at 4, 8 and 20 Gy irradiation group. Resistance to subsequent high dose of radiation of Johong cultivar increased at almost all of the low dose irradiation group. Especially it was highest at 4 Gy irradiation group. Plant groups of Johong cultivar showing the resistance to subsequent high dose of radiation, which had been pre-irradiated with 4 Gy and 8 Gy, were also higher in the carotenoid contents and enzyme activity than the plant group not irradiated previously.
