摘要：The aim of this research was to increase geneticvariability of mangosteen (Garcinia mangostana L.) irradiated by gamma rays dosageof 0 Gy, 20 Gy, 25 Gy, 30 Gy,35 Gy and 40 Gy. Plant materials used were seedscollected from Cegal Sub-village, Karacak Village, Leuwiliang Sub-district, BogorDistrict, West Java. Data was generated from morphological and anatomicalcharacteristics. The result indicated that increasing of gamma ray dosage hadinhibited ability of seed to growth, which needed longer time and decreased seedviability. Morphologically, it also decreased plant heigh, stem diameter, leaf seizure,and amount of leaf. Anatomically, stomatal density had positive correlation withplant height by correlation was 90% and 74%. Gamma rays irradiation successfullyincrease morphological variability until 30%. Seed creavage after irradiationincreased variability and survival rate of mangosteen.
