摘　　要：水稻籼粳杂种不育性是亚种间杂种优势利用的主要障碍。本文首先就影响亚种间杂种F1不育的主要因素及两个主要基因遗传模式进行总结;然后详细综述了相关育性基因的鉴定、定位和克隆等方面研究成果;最后综述了有关克服籼粳亚种间杂种不育性的两个代表性观点,并提出自己简单的看法。The hybrid sterility is a major barrier in heterosis utilization between rice subspecies indica and japonica. In this article, the main influencing factors of inter - subspecific hybrid sterility and two main genetic models were summarized firstly; then the recent progress about identification, mapping and cloning of relevant fertility genes were introduced in detail ; finally, two main representive ideas of overcoming the hybrid sterility between indica and japonica were reviewed, and our simple opinions were put forward.
