Abstract

Mentik Wangi rice has the potential to be developed because Wangi Mentik rice has several advantages namely high prices because it is favored by the community because it has a fragrant odor and when cooked has a fluffier texture and is white. This study aims to determine the performance of the M3 generation mutant rice and select the M3 generation mutant plants as a result of 250 gray gamma irradiation which has short stems with high productivity. This research was conducted in November 2018 РApril 2019 in the experimental field of the Faculty of Agriculture, Sebelas Maret University, located in Palur Village, Mojolaban District, Sukoharjo Regency. The research was carried out by planting  70 M2 lines of 250 gray gamma irradiation and control plants. The observations of the variables in this study were plant height, total number of tillers, number of productive tillers, flowering age, harvest age, panicle length, number of seeds per panicle, panicle bush thickness index, weight of 100 seeds, weight of seeds per clump. Observation data were analyzed descriptively and t test was used to determine the difference of M3 generation of fragrant mentic rice from 250 gray gamma irradiation with control plants (without irradiation). There are 24 individual selected lines of M3 generation of fragrant Mentik Wangi mutants from 250 Gy gamma ray radiation which have a short stem character and have higher productivity than control plants (without radiation).
