To select the herbicide-tolerant callus variants, callus from the brown rice grain of Kwangmyongbyo and Minehikari was inoculated to the culture media containing several different dosages of 2,4-D-Lq(40%), Butachlor-Ec(33%), and Oxadiazon-Ec(12%). The pattern of callus survival percent was different in the two varieties. The limit dose of callus survival was different between the two varieties in 2,4-D and Butachlor, but it was same in Oxadiazon. The callus survival percent was not increased by the succeeding callus culture of the stepwise higher dosage of 2,4-D and Oxadiazon.
