  1. The red-leafed 91.136 B6-77, NZ-selection8, NZ-selection9, NZ-selection10 and 'Geneva' all have Malus pumila var. niedzwetzkyana in their pedigrees. 'Geneva' is an open-pollinated seedling of Malus pumila var. niedzwetzkyana, NZ-selection8 and NZ-selection9 are seedlings from a 'Royal Gala' × 'Geneva' cross. NZ-selection10 is a seedling of a ('Royal Gala' × 'Prima') × 91.136 B6-77 cross. The origin of red foliage colour in 94.036 K-84, 92.087 D35-51 and 93.014 J12-09 is unknown. The green-foliaged breeding parents NZ-selection2, NZ-selection3, NZ-selection4, NZ-selection6, NZ-selection7, and 'SciGold' are from a 'Royal Gala' × 'Braeburn' cross, NZ-selection5 from a 'Red Delicious' × ('Gala' × 'Splendour') cross and NZ-selection1 from a 'Royal Gala' × 'Prima' cross. †: A194 population used for genetic map construction. χ2 test for segregation: * P(χ2 > 3.84) = 0.05; *** P(χ2 > 7.87) = 0.005.
