This study aims to obtain information on the differences in vegetative and generative characters of M2 generation rice mutants compared to wild types (MSP13 line) and commercial cultivars (IR64 and Ciherang). Gamma ray radiation treatment at 200 Gy was carried out on MSP13 line rice seeds in the M0 generation. The observation variables included plant height, number of productive tillers, age at harvest, weight of well-laden grains, and weight of 100 grains. The data obtained were analyzed by t test and cluster analysis. The results of t test showed that there are three M2 generation of mutant rice plants that have shorter plant sizes (dwarf), potential number of productive tillers, early harvest period and yield, compared to the wild type (MSP13 line), Ciherang and IR64 cultivars. Cluster analysis based on vegetative, generative and yield characters, obtained groups consisting of 9 and 66 rice mutant individuals with 21.87 % and 21.11 % similarity respectively compared to other rice mutant groups as well as wild type, Ciherang and IR64 varieties.
