| 摘 要： | 本文运用数量分类方法,对产于湖南、江西两省的普通野生稻居群和性状进行了聚类分析。结果初步揭示了分布于我国北界的普通野生稻居群的类型和性状间的关系,表明环境因素是决定居群类型的重要原因;东乡县两居群高度游离于所有其它居群,充分说明了其高度的特殊性和它们之间的遗传异质性。

| Abstract: | Clustering analyses of 10 populations of Oryza rufipogon Griff. from Hunan and Jiangxi Province, China were undertaken and 25 characters analyzed by means of numerical taxonomic methods, The populations were classified into 5 types, The relationships among the characters were discussed, It is shown that the evironmental factors play an important role in population differentiation, The fact that the two populations from Dongxiang County, Jiangxi are highly isolated from all the others, shows their high specificity and genetic divergence to each other. |
