  1. C: Four apple cultivars, including ‘Golden Delicious’, ‘Jonathan’, ‘Luao’, and ‘Starkrimson’. W: Four wild apple species, including M. prunifolia (Willd.) Borkh. (‘Regunzihaitang’), M. sieversii (Lebed.) Roem. (‘Xinjiangyepingguo 12’), M. × robusta Rehd. (‘Pingding Crab’), and M. asiatica Nakai (‘Naizi’). C+W: Both four apple cultivars and four wild apple species.
