摘　　要：随着农业用水资源的短缺,水稻种植模式的转变以及人们对农田生态系统保护意识的增强,具有干旱抗性的水稻品种越来越受到人们的重视。该文综述了水稻生长生态系统、抗旱性遗传生理机制以及水稻抗旱性育种选择策略。With the deficiency of agricultural water resource and the changing of rice cultivation model,as well,consciousness enhancing on the conservation of the agricultural field ecological system,rice varieties with drought resistance was increasingly important for human. This paper reviewed the rice ecosystem and main physiological mechanism contributing to yield maintenance during drought conditions,as well,the breeding methodologies available for rice breeders aiming to improve drought resistance.
