Popis: This study aims to determine the character and heritability of the M3 generation of red rice (G16) mutant plants produced by gamma ray irradiation of 300 Gy. This experiment was carried out from May to September 2022 in Nyurlembang Village, Narmada District, West Lombok Regency, West Nusa Tenggara, using a Randomized Block Design (RBD) in a partitioned design. With a total of 25 treatments consisting of 22 genotypes of mutant plants and three comparison plants. The results of the observations were analyzed using the analysis of variance with a level of 5%. Then the significantly different treatments were further tested using the Honestly Significant Difference test at the 5% level. The results showed that the gamma ray irradiation treatment of 300 Gy in the M3 generation of brown rice (G16) caused differences in the characters of each genotype including the number of non-productive tillers, number of empty grain panicles, panicle length, weight of filled grain, total number of tillers, the number of filled grain and the weight of empty grain. The best character in mutant plants GM20, GM26, GM27, GM30, and GM52. Meanwhile, the heritability of the M3 generation mutant brown rice (G16) produced by gamma ray irradiation of 300 Gy was classified as high heritability values ​​obtained for the character of plant height, number of non-productive tillers, panicle length, number of panicle filled grain, number of empty panicles, weight of 100 grains, weight of full grain, weight of empty grain, and weight of grain per clump. Meanwhile, moderate heritability was obtained for the character of harvesting age and the total number of tillers and low heritability was obtained for the character of flowering age and the number of productive tillers productive tillers had low heredity
