Detailed pair-wise LD r 2 values for all the consensus linkage groups are projected as heat-plot triangular matrices in Additional file 6 : Figure S4, together with the polymorphism index content plots along the chromosomes (reported as standardized average PIC values of a three-marker sliding window) and the distributions of markers with highly significant ( P ≤ 0.01) genetic differentiation ( F ST indexes) among the main sub-populations represented in the panel.
