Genetic diversity and differentiation analysis are essential to manage their conservation and utilization. To provide a conservation and utilization strategy of P. sheareri based on sound genetic diversity and differentiation data. Results: We found medium level of genetic diversity and low inbreeding. Nei's gene diversity and Shannon’s information index value showed medium genetic diversity in nature populations of P. sheareri, which was higher than other two Phoebe species.
