Abstract: 【Objective】 This study analyzed variation on the seed traits of Ormosia hosiei Hemsl. Et Wils. from different producing regions and their correlation with geographical factors to provide data to support seed experiments, the protection of genetic resources, and resource mining of quality germplasm. 【Method】 We collected seeds from 13 O. hosiei origin locations in five provinces including Fujian, Zhejiang, Hunan, Sichuan, and Anhui, to determine differences in characteristics such as longitudinal diameter, transverse diameter, single grain weight, and thickness. Statistics were used to reveal phenotypic variation in seeds from different producing regions and their correlation with geographical factors via single factor analysis, cluster analysis, correlation analysis, and principal component analysis. 【Result】 The phenotypic traits of O. hosiei seeds present abundant variation in characteristics(variability coefficients exceeded 10%). The volume index of variation was the largest, at about 25.39%. Furthermore, correlation analysis revealed that there were significant correlations among the six phenotypic traits, including longitudinal diameter, transverse diameter, single grain weight, thickness ratio of vertical to transverse diameter, and bulk index. Furthermore, these traits were significantly positively or negatively correlated with latitude or longitude. Cluster analysis showed that the seeds of 13 producing regions could be clustered into five groups, and each group presented significant differences in six phenotypic traits. 【Conclusion】 Based on the principal component analysis and construction of a comprehensive evaluation model, these results indicated that the top three seeds are from Sichuan Yaan, Fujian Shaxian, and Anhui Shexian Fuhe. These results provide a basis for the development and utilization of the seed resources of O. hosiei Hemsl. Et Wils.
