Inferred population structure of the collection using the model-based program STRUCTURE [47]. Plots generated with the DISTRUCT software based on the Q-matrix consensus permuted across 10 replications for K = 2 to K = 6 using the CLUMPP software. Each accession’s genome is represented by a single vertical line, which is partitioned into coloured segments in proportion to the estimated membership in the two to six subpopulations. On the y-axes is the likelihood of assignment to any given cluster K. Black line separates individuals of four predefined groups (see Table 1). (a) 22 SSR loci, 1085 individuals, (b) 353 SNP loci, 1072 individuals. * best K choice based on the ΔK method [44]. # best K choice based on the non-parametric Wilcoxon test.
