Objective: Comparison and correlation analysis of polysaccharose contents in Polygonati Odorati Rhizoma from different provenances to provide the basis for superior provenance selection of Polygonati Odorati Rhizoma. Method: The 21 pieces of wild provenance resources of Polygonati Odorati Rhizoma were collected from the main distribution area of China. Their agronomic traits

longitude and latitude

height were measured and recorded. Polysaccharose content was detected by phenol-sulfuric acid method

and then the obtained data were analyzed by Excel

SPSS and DPS software. Result: There were extremely significant difference in agronomic traits and polysaccharose contents between Polygonati Odorati Rhizoma from different provenances (P<0.01). The polysaccharose contents in Hunan and Sichuan provenance were higher

followed by Zhejiang provenance. Polysaccharose contents had low correlations with width of leaves

diameter of rhizome and heights

however

the polysaccharose contents were higher in the lower longitude and latitude provenances from which the plants presented larger area and ratio of length and width of leaves

thicker stem and larger diameter of fruits. What's more

12 characters tested were simplified to 5 principle components

with a cumulative contribution rate of 85.44%. 21 provenances could be divided into 4 groups and the comprehensive characters of the first group showed the best performance. Conclusion: The 8 superior provenances have been selected and more attention should be paid on Hunan and Sichuan Pingchang provenance

followed by Zhejiang Lin'an

Zhejiang Pan'an and Jilin Fusong provenances for superior variety breeding.
