Rodent tuber (Typhonium flagelliforme Lodd.) is a potential medicinal plant that is useful as anticancer, antimicrobial, and antioxidant. Important chemical compounds contained such as alkaloids, saponins, steroids, glycosides, and lectins. Rodent tuber is propagated vegetatively with its tuber. So that, genetic variation of rodent tuber is still relatively low. The aims of this study were to determine the effect of tuber size on the effectiveness of physical mutations and increase the morphological variation of rodent tuber through gamma irradiation. Macro and micro tubers were mutated using gamma irradiation with 0 Gy, 5 Gy, 10 Gy, 15 Gy, 20 Gy, and 25 Gy concentrations. The results of this study indicated that there was an effect of tuber size on the LD20 and LD50 values. Macro tubers were still able to grow at radiation level of 25 Gy, meanwhile micro tubers were only able to grow at a radiation level of around 15 Gy. In general, rodent tuber mutants had shorter growth but had a higher greenish level of the leaves. Macro tuber mutants with a radiation level of 15 Gy showed a higher number of tillers among the other mutants.
