Selection of M3 genotype short stem results of ray gamma 250 gray in Mentik Wangi rice

This study aims to determine the performance of Mentik Wangi rice at 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. The research was carried out by planting 70 M 2 lines of 250 gray gamma irradiation and control plants. The variables observed 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. Following observation, data were analyzed descriptively and statistically compared using t-test to determine the difference of M3 generation of fragrant Mentik 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.
