Neighbor joining dendrogram of relationships between Andean, Mesoamerican, cultivated and wild accessions of common bean. Dendograms are based on different groups of cDNA derived markers: a) newly developed BMc markers 1-120; b) previously developed BMc markers 121-368 from Blair et al. (2009a) and c) all BMc markers from 1-368. The Andean and Mesoamerican genepools are indicated in each case with a subdividing dark line that separates the dendograms in two and with different shades of circles at the end of the branches for cultivated accesssions. Wild genotype accessions are indicated with triangles at the end of the branches and included G19892 (from Argentina), G24390 (Mexico) and G24404 (Colombia).
