Abstract:  Herbicides have become essential tools in modern agriculture for efficient weed control. However, chemical control of weed for rapeseed in China is quite limited. Developing germplasms with special herbicides resistance and breeding herbicide-resistant cultivars are desirable methods for chemical control of weed in rapeseed. Acetolactate synthase(ALS)-inhibiting herbicides have been widely used for controlling weeds due to their low application rates, high margins of crop safety, and their wide spectrums for weed control. This review started with brief induction of ALS genes and mechanisms of resistance to ALS-inhibiting herbicides due to ALS genes mutation, and then focused on development of rapeseed germplasms with herbicide resistance based on target enzyme mutation and research advances in physiological biochemical and molecular bases of herbicide resistance in China. Finally, the usages of rapeseed germplasms with herbicide resistance in the breeding of new herbicide-resistant cultivars and hybrid rapeseed production, as well as applications of herbicide-resistant genes in transgenic engineering were discussed.

Key words: rapeseed, chemical control of weed, ALS-inhibiting herbicides, development of rapeseed germplasms, target enzyme mutation, herbicide-resistant cultivars
