针对草害和杂草抗药性问题,20世纪80年代美、英一些学者提出利用抗药性作物来解决世界农业面临的难题;于是选育抗除草剂作物成为近20多年来育种研究的热点之一。综述了国内外选育抗除草剂作物的进展以及选育机理和方法,并指出了现存问题及今后发展前景。
In response to the problem of weed resistance and weed resistance, some scholars from the United States and Britain in the 1980s proposed to use drug-resistant crops to solve the problems facing the world agriculture. Thus, the breeding of herbicide-tolerant crops has become one of the hot topics in breeding research in recent 20 years . The progress of domestic and international breeding of herbicide-tolerant crops as well as breeding mechanism and methods were reviewed. Existing problems and future development prospects were pointed out.
