The purpose of this study was to determine the effect of cobalt-60 gamma ray irradiation which could expand the genetic security of white taro cultivars (Xhanthosoma sagittifolium (L)). This research has been carried out in June - September 2018 at the Center for Isotope and Radiation Applications, the National Atomic Agency (BATAN) Jakarta, and the Experimental Garden of the Faculty of Agriculture, Andalas University, Padang. Experimental method of gamma cobalt-60 ray irradiation with 0 gray dose; 30; 60; 90; and 120 gray, observations with Single Plant using Student test t test at level 5%. The results showed that the Ld 50 (Lethal dose 50) value, at the level of Gammacell 220 light irradiation (Cobalt-60) occurred in 60 gray, leaf color variation only occurred at irradiation rates of 30 and 90 gray while for plant heights occur at all levels of irradiation.
