Abstract

Mentik Wangi rice is a local rice originating from the Special Region of Yogyakarta which has a distinctive fragrant aroma and fluffier texture. The problems that occur in Mentik Wangi rice cultivation are that the harvest time is longer, and the plants are too high so that it gives a potential lower production impact because it is easy to collapse. One way to overcome this problem is through plant breeding with gamma ray irradiation. This study aims to determine the performance of the Mentik Wangi mutant strains so as to get mutant strains that have short stems, early maturity and high productivity. The research was carried out by planting 35 M5 strain codes resulting from 100 gray gamma ray irradiation and control plants (without irradiation). The variables observed were plant height, flowering age, harvest age, total number of tillers, number of productive tillers, panicle length, number of seeds per panicle, bushiness index, weight of 100 seeds, and weight of one clump. Observation data were analyzed descriptively followed by T-test to compare the performance of Mentik Wangi M5 rice plants from 100 gray gamma irradiation with control plants. The selection results of Mentik Wangi M5 rice plants from 100 gray gamma irradiation amounted to 21 individual plants namely M-MW1-G35-02-06-19 (70) (81) lines, M-MW1-G35-02-06-20 lines (82) (76), M-MW1-G35-02-06-13 (90), MM-MW1-G35-02-06-01 strain (105), M-MW1-G12-01-18-01 strain (86) (88) (109), M-MW1-G12-01-18-01 (70) strain, M-M-MW1-G12-01-18-05 strain (8) (41) (69), strain M-MW1-G80-11-08-15 (20) (29) (50) (15), M-MW1-G89 lines-20-03-01 (11) (21), and M-MW1-G89 lines -20-12-17 (33) (76).
