[Objective] The aim was to study the correlation among several quantitative characters of Prinsepia utilis Royle. [Method] Taking P. utilis in Shangbaimai Village, Daju County, Lijiang City as tested materials, correlation analysis, path analysis and principal component analysis of the quantitative characters were conducted, in order to find out the quantitative characters directly affected and had close correlation with the yield formation. [Result] The yield of P. utilis was closely related to crown width and fruit number per inflorescence, among which crown width affected the yield per plant mainly through fruit number per plant. Therefore, the relationship between crown width and fruit number per inflorescence should be coordinated during production. Besides, there was positive correlation between single fruit weight and yield per plant, which should also be paid attention during production. [Conclusion] This research provided references for the high-yield cultivation and breeding work of P. utilis in future.
