Origin & Breeding History: 'KAR27' arose from the cross 'C13-05-01' as the female parent with 'S34-01-19' as the male parent which was conducted in 1978 at the Agriculture & Agri-Food Research Station in Kentville, Nova Scotia. Seedlings of the initial cross were grafted on the semi-dwarf rootstock MM.106 and were planted out in a replicated trial in 1978. The selection criteria included freedom from apple scab and other diseases, fruit colour and flavour.

Tests & Trials: Tests and trials were conducted in 2008 and 2009 at the Agriculture & Agri-Food Horticulture Research Center in Kentville, Nova Scotia. The original planting consisted of 7 trees of 'KAR27', 12 trees of 'Novaspy' and 9 trees of 'Liberty'. The trial was planted in 1998 in a RCB design, with trees spaced 3.5 meters apart within the row and rows spaced 5.0 meters apart.
