摘　　要： 考察粤东地区普通野生稻群体及其居群间的表型变异情况,包括质量性状和数量性状的表型性状共计23个,根据调查数据分析表型变异,并结合SPSS和DPS软件进行表型相关、聚类和方差分析。研究结果表明:粤东普通野生稻在表型性状上存在丰富的变异,众多重要性状之间呈极显著相关性,所聚类的7类粤东普通野生稻植株群体存在显著性差异;各居群材料既具有较高的相似性、没有种的变异,又存在一定程度的差异、具有各自的特点,粤东普通野生稻的表型变异具有一定的规律性。 The paper studied the wild rice population and phenotypic variation in which included qualitative traits and quantitative traits of a total of 23 phenotypic traits in the eastern region of Guangdong province, according to the survey data analysis, phenotypie variation, combined with DPS software SPSS and phenotypic correlation, clustering and analysis of variance.The results showed that：The eastern wild rice in a rich phenotypie variation exists, many important traits was significantly correlated, the cluster of seven eastern wild rice plants classes were significant differences between groups; the population material not only had high similarity, there is no variation of species, but also a degree of difference, with their own characteristics, eastern wild rice of the phenotypie variation with a certain regularity.
