Genetic origin of C. canephora cultivated overseas accessions. Scatter plots from the DAPC analysis, showing the 81 C. canephora accessions analyzed. a Discriminant axes 1 and 2 (left) and 3 and 4 (right) representing the five groups (inertia ellipses) determined by the DAPC, as explained in Fig. 2. Empty circles represent reference accessions used to identify genetic groups, as in Fig. 2, while empty triangles represent interpolated individuals from Vietnam and Mexico. b Bar plots of the posterior membership probabilities obtained with the DAPC analysis. The top barplot represents the five groups found, while the bottom shows the sub-groups derived from group 2. The names of the 34 accessions used to identify the genetic groups are highlighted with an (*), and written in bold characters
