Genetic variability of ginger germplasm was low, therefore it was necessary to broaden genetic variability using gamma irradiation. This research aimed to see the effect of irradiation on the growth of small white ginger. This study was conducted in the Plant Breeding Laboratory, Indonesian Spice and Medicinal Crops Research Institute and the Cicurug Experimental Garden Sukabumi from June 2010 to May 2011. Irradiation was undertaken in P3TIR, BATAN, Jakarta. The experiment was arranged in a split plot design with the main plot was two accessions HALINA 1 and ZIOF 00 48, and the sub plots was 11 irradiation doses (0-50 Gy) with 5 Gy interval. The experiment was replicated three times. Parameters observed were quantitative and qualitative characters at 2,3 and 4 months after planting (MAPs). Results showed that accession influenced radiosensitivity. Accession HALINA 1 was more radiosensitive than ZIOF 0048, indicated by LD50 of HALINA 1 was 11.0693 Gy, lower than ZIOF 0048 13.4254 Gy. Interaction between accessions at 5 and 10 Gy showed the highest plant height, leaf size, and number of shoots. Irradiation dose affected plant height, leaf size, stem diameter and length, and number of leaf. The plant growth increased in conjunction with plant age, but the higher irradiation dose, the growth of plants slowed down. The best plant growth was obtained from 5 Gy, not different from control. The highest rhizome weight (964 g/plant) was obtained from HALINA 1 treated with 10 Gy, differ from control (545 g/plant) and the other treatments.
