Background and Aims Assessment of genetic differentiation ( GDF ) is currently of great interest in studies of population genetics. The optimum estimators for GDF among E uvitis species have not yet been reported. This study aimed to characterise GDF patterns in E uvitis . Methods and Results Within and among the 29 E uvitis species GDF was analysed using 5800 nuclear single‐nucleotide polymorphisms from 30 gene fragments. Mantel tests and principal coordinate analysis ( PCoA ) indicated the pairwise differences ( PW ) and the corrected mean number of PW have the most potential for assessment of GDF among E uvitis species. All 29 E uvitis species were significantly differentiated from each other ( P < 0.05). Species from A sia and A merica were assigned to the independent quadrants in the PCoA plots, A merican species were clustered into two groups and two E uropean species were closer to A sian than to A merican species. Conclusions The overall GDF pattern of all 29 E uvitis species had a limited distribution in the PCoA plots, suggesting a narrow range of genetic diversity ( GDV ) within these 29 species on the whole. Genetic diversity of species varied extensively among the 29 species. Correlation between GDV within and GDF among 29 E uvitis species was not significant. Significance of the Study This study not only adds greatly to our knowledge of the genetic features of E uvitis species but also provides strategies for related studies in other living species.
