中国普通野生生稻的原始型及其是否存在籼粳分化的初探

 选用国内7省（自治区）571份，国外27份普通野生稻编号根据10个形态状进行了聚类分析并结合同工酶分析与野生稻原产地生态考察将中国普通野生稻划分为多年生和一年生两群共7个类型。提出中国存在一年生普通野生稻及原始型普通野生稻问题，并根据同工酶4个基困位点分析对另中国普却生稻是否存在籼粳分化问题进行了讨论。

The Preliminary Study on the Primitive Type of Oryza rufipogon Griff. in China and Its Hsien-Keng Differentiation

A cluster of 571 strains of common wild rice (Oryza rufipogon Griff.) from 7 provinces of China, 27 strains from external nations, based on 10 morphological characters with isozyme analysis and ecological investigating the habitats of wild rice showed the Chinese common wild rice may be devided into perennial and annual groups and 7 types. The authors proposed the presence of annual wild rice in China and primitive type of Chinese common wild rice as well as the morphological and ecological characteristics of the ancester of Chinese cultivated rice. Furthermore, whether the wild rice in China differentiated into Hsien and Keng types was discussed based on analysis of four isozyme loci.
