Origin & Breeding History: 'September Sentinel' was derived from the cross 8H-09-01 x Co-op 27 using traditional breeding methods made at Pacific Agri-Food Research Centre, Summerland, British Columbia in 1989. The material from the seedling cross was propagated on Malling 26 rootstock in Summerland, British Columbia in 1994. The resulting tree was given the breeder reference # 11W-61-23. 4 propagations were made on Malling 26 rootstock in 1996 and planted in 1998 and further propagations being made on Malling 26 roostock in 1997 and planted in 1999. Evaluation on the selection began upon fruiting, with the selection criteria being fruit appearance, taste, flesh texture, tree quality, productivity and precocity.

Tests & Trials: Tests and trials were conducted during 2007-2008 at Pacific Agri-Food Research Centre, Summerland, British Columbia. There were 5 trees of each variety. Trees were planted 0.60 meters apart within the row with rows being spaced 4.5 meters apart. The trees were planted in 1996 on M26 rootstock.
