Table 3. FST-based genetic differentiation for 13 nuSSR markers in a) 345 Andean and Mesoamerican accessions of common bean from America and Europe and b) in ‘pure’ (not admixed) Andean and Mesoamerican common bean accessions as identified on the basis of both chloroplast and nuclear markers and by STRUCTURE analysis.
