    Abstract:

    The quality of grass cloth for clothing is limited by the raw material ramie used for making the cloth. The evaluation and selection of excellent resources of ramie varieties are the basis for the production of high quality grass cloth materials. In this study, 30 ramie varieties (germplasms) were used as experimental materials, and Liuyangjigubai and Ribenzhaohecunma were used as controls. By comparing the diameter and strength of individual fibers, 14 ramie varieties were found to be superior to the controls. Difference analysis, correlation analysis, principal component analysis and cluster analysis were carried out on 8 indexes of the 30 ramie varieties and CK1. Significant differences among the varieties, and among some of the indexes were found. The 30 varieties and CK1 could be divided into 3 categories, and the number of evaluation indexes could be simplified to 6. The varieties better than the control CK1, selected by the method of membership function analysis, were Dayonghuangkema (No. 18),including Gema (No. 11)and Lechanghuangpizhu(No. 3).
