  1. Repartition of the accessions of the different subspecies among the 10 clusters identified by DAPC, and quality measures of the assignments to clusters and metagroups.
  2. C2, C4, C5, C6 are the 4 genetic clusters belonging to the ‘central pack’.
  3. Metagroups have been defined based on the repeatability of the groupings in 15 additional runs (see text). The repeatability corresponds to the average proportion of the individuals from the original metagroup that were assigned together to a similar metagroup in the repetitions.
