摘　　要：出苗难、除草难度大、后期倒伏是影响直播稻生产的主要因素,综述了与直播稻有关水稻中胚轴伸长特性、耐低氧发芽、抗除草剂、抗倒性的研究现状,并展望了适合于直播高产栽培是今后育种的首要目标。There are many factors affecting the growth and development of direct-seeding rice, such as low emergence rate, difficult weeding, and lodging in later growth period. In order to provide theoretical basis for the production of direct-seeding rice, this article summarized the research progress in the characteristics of mesocotyl elongation, hypoxia-tolerant germinability, herbicide resistance, and lodging resistance of direct-seeding rice, and put forward that enhancing the adaptability of direct-seeding rice to high-yielding cultivation was the primary breeding goal in the future.
