(a) Genetic structure of diversity group G: first two axes of the associated factorial analysis from a dissimilarity matrix and (b) corresponding NJ tree. The percentages of total variability are given for each axis. Some coherent subgroups have been identified. For the NJ tree, bootstrap values obtained from 5000 iterations of bootstrap procedure are indicated. For clarity, only values greater than 60 are printed. Unit colors are based on STRUCTURE assignment for each genotype. Probabilities of ancestry greater than 0.6 were considered.
