Abstract: The goal of drought-resistant breeding of rapeseed (Brassica napus L.) is to cultivate water-saving and high-yield new varieties under drought conditions. In this research, drought-resistance identification of rapeseed was studied through morphological and growth indicators, physiological and biochemical indexes (including photosynthesis, osmotic adjustment, antioxidant enzyme activity, endogenous hormones, water use efficiency, etc.), yield and quality indexes, and comprehensive evaluation indexes, etc. It was found that water stress had an important influence on the morphology and growth of rapeseed at different stages. The existing problems in drought resistance identification of rapeseed were analyzed by retrospective study, while the relevant indexes and techniques were discussed to provide references for research and production of rapeseed drought resistance. It is concluded that the molecular mechanism of rapeseed drought resistance would bring drought resistance breeding to a new stage.
