The results showed that the spikelet fertility performed qualitative-quantitative trait.Dongxiang wild rice possessed one or two pair of restorer alleles for CMS-DA and CMS-IA.

• 结果表明：东乡野生稻对矮败(CMS-DA)和印尼水田谷败育(CMS-IA)的育性恢复表现为质量-数量性状，结合群体遗传结构、育性分布和东乡野生稻的偏粳性及广亲和性，可知东乡野生稻对CMS-DA和CMS-IA的恢复性由1对或2对恢复基因控制。
