    Red sorghum variety of Suri 3 has been developed as a food ingredient. The problems of developing the Suri 3 varieties of food raw materials include the low production and non-fluffy taste of this variety. Therefore, genetic diversity improvement was carried out by induced mutation using gamma rays. Radiation using gamma rays for the genetic repair of plants has developed and produced various new varieties of horticulture, food, and plantation crops. This study aims to determine the effect of the radiation on agronomic characters of M2 mutant lines of Suri 3 variety. The study was conducted at the Cikeumeuh Experimental Station of the Center for Agricultural Biotechnology and Genetic Resources Research and Development in Bogor from October 2020 to March 2021. The plant material used in this study was M2 mutant lines of Suri 3 variety from gamma-ray irradiation 0, 40, 50, 60, and 70 Gy. The parameters observed were panicle length, panicle diameter, wet and dry panicle weight, sugar content (brix), and weight of 100 seeds. The observations indicate that there is an effect of radiation dose on changes in agronomic characters. Radiation dose of 40 Gy produced variations in the sugar content (brix), whereas radiation dose of 60 Gy resulted in variations on the traits of panicle length, panicle diameter, wet panicle weight, dry panicle weight, and weight of 100 grain. The results showed that the gamma-ray radiation of 40 and 60 Gy produced characters superior in sugar content (brix), panicle length, panicle diameter, panicle weight, and 100 grain weight.
