^aApples shown with an underline are susceptible (Alt/alt) to Alternaria blotch. Morioka 59: Kitakami × Hatsuaki, Morioka61: Tsugaru × Kitakami, 5–6393: Akane × 4–23 (Fuji × [Golden Delicious × Indo]), 4–547: Fuji × Hatsuaki, 4–161: Hatsuaki × Starking Delicious, 5–3645: Sansa × Tsugaru, 5–5102: Tsugaru × Fuji. A graphical illustration of the pedigree of susceptible apples is also shown in Additional file 1: Figure S1
^bIndividuals in which recombination occurred between Mdo.chr11.27 and Mdo.chr11.44
