Abstract: To screen out excellent jute germplasm resources, improve the information of jute germplasm resources, and increase the utilization rate of jute germplasm resources, this study took 15 jute germplasm resources as the research object, measured their phenotypic traits and fiber strength, and comprehensively evaluated them by using the principal component analysis and the analysis of the value of the affiliation function.The results showed that the coefficients of variation of the phenotypic traits of jute ranged from 4.14% to 159.52%. One of the traits with the highest coefficient of variation was the number of forks, indicating the abundance of genetic variation in jute. In this study, 21 agronomic traits were synthesized into six major components using principal component analysis, and the factor with the highest loading was branching height. Further calculating the value of the affiliation function, the top three varieties are HF2-13, Zhe Xiaoyuan 1, and Fuhuangma 13, which have high potential for development and utilization. By further calculating the value of the affiliation function, the top three varieties are HF2-13 (1), Zhexiaoyuan 1, and Fu Jute 13.These three varieties possess relatively high potential for development and utilization. This study clarified the differences in fiber strength of different germplasm resources, and successfully screened out the germplasm resources with excellent comprehensive performance. This study provides data support and theoretical basis for the improvement of jute varieties, the utilization of germplasm resources and the development of related industries.
