Varieties used for comparison: 'Royal Gala', 'Splendour', 'Ambrosia' and 'Fuji BC2'

Summary: 'SPA493' is an apple variety with a late to very late harvest date, maturing after 'Splendour', 'Ambrosia' and 'Royal Gala' and before 'Fuji BC2'. 'SPA493' has longer and wider leaves and flowers earlier than all the reference varieties. The fruit of 'SPA493' are medium in size, whereas 'Royal Gala' and 'Ambrosia' have large fruit and 'Splendour' and 'Fuji BC2' have very large fruit. The fruit of 'SPA493' are globose, compared to globose conical for 'Royal Gala', 'Splendour' and 'Ambrosia' and ellipsoid conical for 'Fuji BC2'. The fruit stalk is longer and thinner than the stalk of the reference varieties. The fruit has a yellow ground colour with high to very high amount of red blush overcolour. By comparison, 'Splendour' and 'Fuji BC2' have green yellow ground colour and 'Ambrosia' has a cream white ground colour. 'Fuji BC2' has a moderate amount of blushed and streaked red and dark red overcolour and 'Royal Gala' has a high amount of blush, streaked and flecked red overcolour.

Origin & Breeding History: 'SPA493' is the result of a cross between 'Splendour' and 'Gala' made in 1981 at the Agriculture & Agri-Food Canada Pacific Agri-Food Research Centre, in Summerland, British Columbia. The material from the seedling was propagated on M26 rootstock and a resulting tree was given the breeders reference number 8S-62-61. In 1992 evaluation began upon fruiting. Selection criteria included fruit appearance, taste, flesh texture, tree quality, productivity and precocity. Upon selection for further testing the selection was designated 'SPA493' in 1997.

Tests & Trials: Trials were conducted by Okanagan Plant Improvement Corporation during the summer and fall of 2004 at the Agriculture & Agri-Food Canada, Pacific Agri-Food Research Centre in Summerland, British Columbia. 'SPA493', 'Royal Gala', 'Ambrosia' and 'Fuji BC2' were grown on M9 rootstalks with 'Splendour' on M26 rootstalk.
