영문 초록

Several doses of butachlor ranged from 0 to 50 ai kg/ha were treated on the sandy soil and rice seedlings with 2~3 leaf stage were transplanted. There were no difference of injury by butachlor between 20℃ and 30℃. The optimum dose of butachlor to search the resistant varieties was estimated 30 to 40 ai kg/ha. Seventeen varieties among 392 rice varieties screened to butachlor were moderately resistant. The resistance of cultivar Kwanagbyeo and IR 667-98 were found to be controlled by a single recessive gene in the segregation of F₂ generation of cross combinations between the resistant and susceptible varieties.
