Abstract: Twenty\|one wild germplasms of Tetrastigma hemsleyanum from different provenances were collected. Biological characters, survival ratio of cuttage and agronomic traits were measured, counted, and analyzed. The results showed that there were significantly differences in the above characters among different germplasms. The average survival ratio was 697%. Besides, the agronomic characters of Chongqing and Guangxi germplasms were superior than those of Zhejiang, Jiangxi and Fujian germplasms. Whats more, nine agronomic traits were simplied to four principal components, whose accumulative contribution rate was 906%. In addition, twenty\|one germplasms were classifed to four groups, the agronomic traits of germplasms in group Ⅰ and group Ⅱ were superior. Pubescence on leaf, stem shape and tuber surface could be used to distinguish Zhejiang, Hunan, Hubei germplasms from Guangxi, Chongqing germplasms. In terms of agronomic traits, the superior germplasms of Tetrastigma hemsleyanum could be selected among Chongqing and Guangxi germplasms preferentially. Based on the work above, six superior germplasms have been selected preliminarily.
