^a Linkage group designations (1–14) are based on the B. thunbergii cv. ‘Kobold’ genome assembly. Linkage Group 1 anchors to the longest pseudo-molecule in the Kobold assembly (99.76 Mbp); Linkage Group 2 to the next longest (99.56 Mbp); as so on to Linkage Group 14 (54.72 Mbp) (see Additional file 2: Table S2)
