Origin & Breeding History: ‘8S5505' originated from a cross conducted between ‘8S6923' and 'Co-op 25' at the Summerland Research and Development Centre in Summerland, BC in 2000. The variety was promoted to a second test in 2007 and selected for its taste, texture, appearance and storage qualities. Propagation is clonal through budding and grafting onto budwood.

Tests & Trials: The comparative trial for ‘8S5505' was conducted in 2024 at the Summerland Varieties Corp. trial block in Summerland, BC. The trial consisted of a minimum of 10 trees per variety planted in 2009 and grafted onto M9 rootstock. Trees were planted approximately 0.9 metres apart within a row and the rows were 3 metres apart. Observations and measurements were taken on 10 trees or 10 parts of trees for all varieties. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
