Discriminant analysis of principal component (DAPC) scatterplot. Showing the relative location of each individual sample in two dimensional space, overlaid by a minimum spanning tree calculated from the squared distance between individual to represent the phylogenetic relationship between inferred clusters. K5, hemp or “ruderalis” appears ancestral and the most differentiated group, followed by K4, terpinolene dominant resin accessions. The genetic distance between groups (Fst) is indicated on the respective branches of the minimum spanning tree
