The effects of gamma irradiation on sprouting and on the chemical changes which take place in "Florido" variety of Dioscorea alata yam tubers grown in Puerto Rico, were investigated. Irradiation with 7.5-Krad doses did not have appreciable effects on the chemical composition of the tubers but prolonged their dormancy period by 4 additional months. It is suggested that 7.5 Krad is the optimum dose for the inhibition of sprouting in this variety of yam. This treatment makes possible the availability of good quality yam tubers out of season. The loss in weight of the treated tubers was relatively low. Irradiated tubers were found very acceptable by sensory evaluation.
