Abstract:

Weed is one of the most serious biological disasters that seriously damage the yield and quality of Brassica napus. Cultivating herbicide resistant B. napus varieties is an effective and economic way to control weeds in rapeseed field. In this paper, three kinds of herbicides, glyphosate, glufosinate and ALS enzyme inhibitors, which have the greatest potential for field application are mainly reviewed. The mechanisms of herbicide action and herbicide resistance are summarized. The research advances of B. napus resistant germplasms in China and abroad are further reviewed according to the germplasm creation methods. Finally, the development strategies of herbicide resistant rapeseed germplasm are put forward: strengthening the research of resistance mechanism and gene exploration, and using new technologies such as gene editing to create new non-transgenic rapeseed germplasms with multi herbicide resistance.

Key words: Brassica napus, herbicide resistant, germplasm, mechanism
