Cluster analysis of T. turgidum accessions using PCoA. Accessions from subsp. durum are shown with circles, subsp. dicoccon with squares, subsp. turgidum with triangles and the reference varieties with asterisks. a Graphical representation of PCo1 and PCo2 for the whole collection of durum wheat. Accessions are colored according to their Vrn-A1 alleles. b Graphical representation of PCo1 and PCo2 for subsp. durum accessions, which are colored according to their STRUCTURE population assignment
