Abstract: The principal component analysis of 11 physical property indexes such as fineness of fiber,breaking strength of 107 ramie varieties was undertaken using the statistical analysis system(SAS).Three principal components were chosen according to the criteria of cumulative contribution root≥90%.The 107 ramie varieties were cluster analyzed on the result of principal component analysis,and these varieties were divided into four clusters.In terms of comprehensive physical properties,cluster Ⅰ and Ⅳ: moderate;cluster Ⅱ: fairly good;and cluster Ⅲ: relatively poor.
