Dihydrochalcones are abundant in Malus Mill. species, including the cultivated apple (M. ×domestica Borkh.). Phloridzin, the primary dihydrochalcone in Malus species, has beneficial nutritional qualities, including antioxidant, anti-cancer, and anti-diabetic properties. As such, phloridzin could be a target for improvement of nutritional quality in new apple cultivars. A few rare Malus species produce the dihyrdochalcones trilobatin or sieboldin which also have nutritional value. Through germplasm characterization and genetic studies, we evaluated dihydrochalcone variation in apple and its wild relatives, and identified loci associated with trilobatin and sieboldin production.
