Abstract:

Ase Buluh from Bone Regency is local varieties that currently no longer encountered even almost extinct due to low production, high trunk and easy to fall, aged in, not, therefore, need to be assembled varieties. The purpose of this study was to induce local rice mutation of rice varieties (Ase Buluh) with gamma ray radiation to obtain Lethal Dosage of short and medium-grown local rice mutants. This study was designed using a simple Randomized Block Design (RAK) of one factor consisting of selected lethal dose of seven pretreatment treatments ie without radiation (R0) radiation with 50 GRY (R1), 100 GRY (R2), 200 GRY (R3), 300 GRY (R4), 350 GRY (R5) and radiation with 400 GRY (R6). Each treatment was replicated three times using 50 plants for each treatment. The results of this study obtained a lethal effective dose of gamma-ray radiation are 200 gray and 300 gray. The shortest mutant plant height is 300 gray that is 131 cm not significantly different with 200 gray that is 139 cm. Meanwhile, the number of most tillers obtained at a dose of 0 gray is 18 and is different with 200 gray and 300 grays. The length of panicle showed no significant difference from all treatment while the fastest flowering age at a dose of 300 Gray is 89 days, as well as the fastest harvest age and not significantly different dose 200,grays with 300 gray that is 140 and 141 days compared with 0 gray that is 160 days. Furthermore, it is expected to obtain also local rice mutants Ase Buluh which have an early age.
