## Abstract
Abstract Toraja has diversity of rice germplasm. Aromatic rice is very popular today because of its good quality and fragrant aroma. However its long harvesting period is not comparable to its low yield (2-3 ton ha-1) in 6 month planting season. Efforts to increase production through mutation breeding has been proposed here. The aim of this study is to evaluate the effect of 19 mutant (M2) lines on yield atributes.The study was conducted at Alla District, enrekang regency, South Sulawesi from May to October 2017 using mass selection method consisting of two irradiation treatments, namely: irradiation with Carbon ion dose 150 Gy (PB-C), irradiation with 10 Gy Argon ions (PB-A), and control as a comparison. The result showed that lines that have the best production components is PB-A-14.2.14. Whereas, there are 14 lines that have better production components than controls. Cluster analysis showed that there were 3 main componenets of lines formed into further 5 sub-groups with similarity level 66.67%.
