This study aims to obtain the genotype of local Toraja red rice mutants that have the potential to be developed into early maturing varieties and have high yields. Research carried out with a mass selection method consisting of two irradiation treatments, namely: (1) irradiation with a Carbon ion dose of 150 Gy (PL-C); (2) irradiation with Argon ion dose of 10 Gy (PL-A) and control as a comparison. Selected lines of M2 seed population were planted in experimental rows plus 2 rows as control, each row had 50 plants. Selection is done in two stages. The first stage, the selection was based on the criteria of plant growth components; to select rice plants that have early mid-early maturity characters, dwarf to semi-dwarf, and larger number of tillers. The second stage, selected lines from the scoring method were then grouped based on the degree of similarity with the cluster analysis method. Irradiation with ion beams produced mutants with shorter harvesting age than their. This study produced 10 selected lines, 5 lines of Carbon ion and 5 lines of Argon ion irradiation treatment, and formed 5 groups with a 90% similarity coefficient.
