在喷施豆施乐除草剂的大豆试验田,发现抗咪唑啉酮类除草剂的自生油菜突变株,经连续3年自交纯合和抗性鉴定,该突变体抗咪唑啉酮类除草剂的浓度是除草剂有效杀草浓度的2倍以上,抗性性状稳定、抗性效应明显。该材料的发现对于开发具有自主知识产权的抗除草剂新基因,选育不受环境释放限制的油菜新品种,均具有重大的理论和现实意义。
A rapeseed mutant resistant to imidazolidone was found as a volunteer in the soybean field treated by spraying imidazolidoneherbicide. The resistance of this mutant was steadily inherited and effective,which had been testified by consecutive assessment of several generations in 3 years. The mutant showed resistant to a dose of imidazolidone which was two times of the effective concentration of this herbicide. It is of great theoretical and practical significance for the identification of new herbicideresistant oilseed rape genes with independent intellectual property,also for the development of new varieties against environmental release restrictions.
