Discriminant analysis of principal components (DAPC) of Vietnam isolates (n = 261) grouped by province. Scatter plot of DA eigenvalues 1 and 2 (A) using all biallelic SNPs detected by the Pv AmpliSeq showed a differentiation of Lam Dong and Binh Thuan along the x-axis and a separation of Khanh Hoa province along the y-axis. Scatter plot of DA eigenvalues 3 and 4 (B) groups separately clusters isolates from the most Northern province of Quang Tri. SNPs contributing most to the DAPC are listed in Supplementary Table 2 , Table S6 . DAPC was performed with 60 principal components and 8 discriminants as determined through cross-validation.
