Abstract:

Drought resistance rice has become a hot issue in scientific research of rice. Foster drought resistance rice varieties and realize the varieties of water-saving cultivation are of great significance for water saving and high yield. Research on drought resistance of rice, many researchers were to drought indicators, physiological and biochemical mechanisms of drought resistance, drought tolerance and related gene mapping and cloning has done a lot of research work, and achieved positive results. This paper reviews the drought resistance of rice genetic mapping, gene cloning, breeding methods and breeding drought resistance at home and abroad on the achievements of drought water-saving cultivation techniques outlined, and the current drought resistance in rice is summarized, which would provide a reference for further researching on drought resistance rice in future.
