水稻新型育种技术研究现状与展望

Development Status and Prospect of Rice New Breeding Technology

水稻是我国主要粮食作物之一,提高水稻产量、改善品质一直是水稻育种研究的重要目标。育种技术的改进有利于育种效率的提高,随着科学技术的迅猛发展,水稻育种技术也在逐步完善。对分子标记育种、转基因育种、基因编辑育种和分子设计育种等目前水稻育种中广泛使用的育种技术进行了总结,并进一步展望了不同育种方法的发展前景,以期为水稻种业发展奠定基础。

Rice is one of the major food crops in China,high yield and grain quality has always been the major goal of rice breeding. The improvement of breeding technology is conducive to enhance breeding efficiency. With the rapid development of plant biotechnology,rice breeding technologies have been also gradually improved. This review summarized several widely used breeding techniques in rice,including molecular marker assisted breeding,transgenic breeding,gene editing-based breeding and molecular design breeding,and discussed the development trend of these breeding techniques,which would provide reference for rice seed industry.
