通过对来自中国5个省（自治区）39份普通野生稻（OryzarufipogonGriff，）和33份亚洲栽培稻（O．sativaL．）的核DNA的RFLP分析，探讨了中国普野籼粳分化及其与栽培稻之间的遗传分化关系。结果表明，在核DNA分化上，中国普野可分为原始普野型、偏籼型和偏粳型。中国普野因地理分布不同，其遗传分化表现出多态性：江西东乡和湖南茶陵以及部分云南元江普野既不与籼稻聚在一起，又不与粳稻聚在一起，而独聚一类，其形态上亦比较原始，属于原始祖先型；广东、广西普野则表现为偏籼或偏粳。本研究认为籼粳演化应该是多途径的。
The RFLP analysis of nuclear DNA from 39 wild Oryzarus species (Oryzarufipogon Griffs) and 33 Asian O. sativa (L.) species from 5 provinces of China Relationship between rice genetic differentiation. The results showed that, in the nuclear DNA differentiation, China can be divided into the original wild general wild type, partial and partial japonica type. Due to the different geographic distribution, Pu’er nationality showed polymorphism in its genetic differentiation: Dongxiang in Jiangxi Province and Chaling in Hunan Province, and some Yunnan Province in Yuanjiang Pu’er Province neither clustered with indica rice nor clustered with japonica rice, , Its morphology is also more primitive, belongs to the original ancestral type; Guangdong, Guangxi Pu wild performance of partial indica or partial japonica. This study suggests that the evolution of indica and japonica should be multi-pathways.
