Abstract:

Research  on resistant genes in rapeseed has been one of the most active fields in the oil crops researches, especially on

the transgenic aspect. But the developments on disease-resistance,insect-resistance,herbicide-resistance and drought & cold

resistance transgenic research are different. The emphases of disease-resistant and drought & cold resistant researches are

mainly confined on functional gene cloning aspect, and have not got prominent resistant transgenic lines yet. The researches

on resistances to herbicide and insects have been studied for many years and the technologies are comparatively mature. Some

transgenic rape varieties are already commercialized  in USA and Canada. At present, the studies on resistances to herbicide

and insects are centered on the transgenic cultivars applying and the safety assessment of environmental release.
