Principal Coordinate analysis (PcoA) for qualitative traits. The spatial classification of 144 genotypes of potato was depicted in two first coordinates. Minimum Spanning Tree was added according to distance matrix. Colored capital letters indicate a priori groups as follows: green (interspecific hybrids), grey (CIP clones), pink (North America varieties), black (INTA clones and varieties), yellow (diploid genotypes), red (Group Andígena), violet (Europe-Asia varieties), turquoise (South America varieties). Numbers indicate genotypes. Each dot indicates several co-located genotypes
