水稻籼粳亚种间杂交具有强大的杂种优势，但杂种F1的育性问题严重阻碍其杂种优势的利用，水稻广亲和性被广泛认为是籼粳亚种间杂种优势利用的关键。本文重点概述了近年来水稻籼粳亚种间广亲和性的遗传学研究以及杂种不育基因的定位、克隆及其分子机制研究进展，并探讨了水稻亚种间杂种优势育种利用中存在的问题及解决思路。

There is strong heterosis between indica and japonica subspecies of rice (Oryza sativa L .) , but the utilization of the inter‐subspecies heterosis is seriously restricted by sterility problem of hybrid F1 of indica and j aponica rice .Application of rice wide‐compatibility resources and genes is considered to be a key to overcome the hybrid sterility .In this paper ,we summarized recent advances in genetics research of rice wide‐compatibility ,and the mapping ,cloning and molecular mechanisms of the related genes in recent years ,meanw hile the problems and solutions for the utilization of the inter‐subspecies heterosis in rice breeding were also discussed .
