摘要: 对中国两系法杂交水稻研究理论及育种实践的现状和发展趋势进行了综合评述,认为:选育纯光敏型和广亲和型光温敏核不育系是当前两系杂交稻雄性不育系研究工作的重点;以生物技术为辅助手段朔造水稻理想株型,理想株型与优势利用相结合是超级杂交稻育成的关键;应用分子标记辅助育种与常规方法相合是加速育种进程的有效途径。

Abstract: The status and progress of theories and practices for Two-line hybrid rice breeding was discussed synthetically, the author holds that the most important work is to selected true PGMS or wide compatible PTGMS, combining the ideal plant which develop by biotechnology with the vigor is the key to super hybrid rice breeding, and the effective way is combining the marker assisted breeding with the conventional breeding.
