除草劑 oxyfluorfen과 bensulfuron에 대한 水稻 品種의 抵抗性 檢定

Selection of resistant rice varieties to herbicides oxyfluorfen and bensulfuron

The study was conducted to select the resistant and susceptible rice varieties to oxyfluorfen [2-chloro-4-trifluoromethyl phenyl-3-ethoxy-4-nitrophenyl ether] and bensulfuron [methyl-2-((4,6-dimethoxy pyridin-2-yl) aninocarbonyl) aminosulfonyl-methyl benzoate] among 400 germplasms. Mushakdanti, Weld Pally, NP. 125, K-1, CI 5483-2, Bonsaiookuro were selected as the most susceptible, and Aichiasahi, Chokoto, Ahgabyo and IR 3941 as the most resistant rice varieties to oxyfluorfen, respectively. H 93(3)F. A., H 94(9)F. A., Padilabou alumbis, and IR 1846 were selected as the most susceptible, and Kunmakosa-early, Taichung T.C.W.C., UCP 28, Chinsurah BoroⅡ, Fukunohana and Homarenishiki as the most resistant rice varieties to bensufuron, respectively.
