Mentik Wangi rice is a local varieties native to Indonesia. Mentik Wangi has a characteristic shape of oval round rice, yellow brown rice, and fragrant rice aroma. Mentik Wangi has a weakness that is relatively long harvest time, the plant is too high so it easily fell. This research aims to determine the performance of M5 generation of mutant rice and to select M5 generation of mutant plants as a result of 200 gray gamma irradiation which has short stems with high productivity. This research was conducted in November 2018 – April 2019 in the experimental field of the Faculty of Agriculture, Universitas Sebelas Maret, located in Palur Village, Mojolaban, Sukoharjo. The research was carried out by planting 36 genotypes, namely 35 M4 lines of 200 gray gamma ray irradiation and control plant (without irradiation). Observation data were analyzed descriptively and t test to determine differences in M5 generation of Mentik Wangi rice from 200 gray gamma ray irradiation with control plants (without irradiation). Based on the research results that Mentik Wangi rice plants with gamma ray irradiation 200 Gray have better performance compared to control plants (without irradiation) and there are 28 individual M5 Mentik Wangi rice mutants selected by short-stemmed plants and have high productivity.
