Black rice cempo ireng (Oryza sativa L.) is one of the local varieties of Indonesian rice containing high anthocyanins. Black rice has a weakness that is a high content of amylose which causes rice texture to become pera. This research is a follow-up study that aims to examine the quality of results and performance of three promising lines black rice generation M7 result gamma ray irradiation, expected to obtain a line that has superior quality results and performance. This research was conducted in December 2019 – January 2021. Cultivation is carried out on the rice fields of Ngijo Village, Tasikmadu, Karanganyar, Central Java. Laboratory testing was conducted at Chem-mix Pratama Laboratory in Jambidan Village, Banguntapan, Bantul, DIY. Testing of vigor and viability of seeds was conducted at the Greenhouse Faculty of Agriculture, Sebelas Maret University. This study used the treatment of differences in lines namely three promising lines (8, 44 and 51) resulting from gamma ray irradiation and control (without irradiation). Selection of samples in the field using simple random sampling techniques. Laboratory test samples are selected randomly per line. The observation data was analyzed descriptively to compare three promising lines of gamma ray irradiation black rice expectations with control (without irradiation). Observation variables include anthocyanin content, amylose content, protein content, fat content, vigor and seed viability, organoleptic and seed pericarp color. The results showed that the three promising lines of black rice cempo ireng gamma ray irradiation results have superior quality results and performance compared to control (without irradiation). Promising line 44 have advantages: anthocyanin content (75.11 ppm), organoleptic (3.53: like/neutral), seed pericarp color (4: dominance of black color in one seed by 100%). Promising line 51 has advantages: amylose content (8.43%), protein content (7.48%), fat content (1.59%), vigor and seed viability (80% and 64%).
