The QPgr-3S region on the short arm of B. thunbergii chromosome 3. a Full genetic linkage map of chromosome 3; b Enlarged linkage map of the short arm of chromosome 3, with the QPgr-3S QTL region indicated in orange between its two flanking markers, M411 and M969; c LOD plot of the QPgr-3S region (top) and the context of the single QTL peak across the 14 chromosomes of B. thunbergii (bottom). The dotted red line indicates the threshold for QTL significance (LOD = 3.9), determined via permutation analysis
