Abstract

Mentik Wangi rice is a local variety that is quite popular with the people of Magelang. Mentik Wangi rice has a distinctive aroma and has a fluffier texture. The disadvantage of Wangi Mentik rice is the potential for lower production and also relatively high crops. There is an effort done to overcome that problem were planted mutation through the utilization of gamma-ray irradiation. The aim of this research is to select M3 generation mutant rice resulting from 200 Gray gamma-ray irradiation which has a short stem and has higher productivity and preparation of the performance of M3 generation mutant rice resulting from 200 Gray gamma-ray irradiation. The observational data were analyzed descriptively and compared the performance of the Mentik Wangi M3 rice plants as a result of 200 gray gamma-ray irradiation with control plants (without irradiation) through T-test analysis. The results showed that the performance of the M3 generation of Mentik Wangi rice was better than control plants, there were several strains with potential mutants traits based on the positive character of each individual. The M3-200-G147-10 strain with an irradiated dose of 200 grays has the shortest plant height of  96 cm. The M3-200-G29-11 strain, with an irradiated dose of 200 grays has the highest productive tiller of 22.80 stems. The M3-200-G147-4 has the highest panicle thickness index of 6,65 and The M3-200-G147-2 strain has the highest seed yield per plant of 50,52 gram.
