Figure 1.
Principal coordinate analysis (PCoA) of nuSSRs diversity among 345 Andean and Mesoamerican accessions of common bean from America and Europe.
The samples are color coded according to their gene pool and the continent of origin as identified by Bayesian STRUCTURE analysis.
Figure 2.
Population structure and membership fraction at K=2 for 345 Andean and Mesoamerican accessions of common bean from America and Europe estimated with STRUCTURE analysis for 13 nSSR and sorted by continent.
Each accession is represented by a vertical histogram with two colors segments that represent the individual’s membership fraction in two clusters. The symbols under individual accessions indicate that the cpSSR haplotype (star) and/or Pv-shatterproof1 allele (circle) and/or the Phaseolin type (square) are not in agreement with the Bayesian assignment to the gene pools (Andean vs. Mesoamerican) thus the accession is considered of hybrid origin.
