Origin & Breeding History: 'AAC Eversweet' originated from the cross, 'Kestral' X the Kentville seedling S17-01-02, conducted in 1985 at the Agriculture and Agri-Food Canada Atlantic Food and Horticultural Research Centre in Kentville, Nova Scotia. The seedlings from the original cross were planted in a seedling block in 1987, re-propagated and planted in a comparative field trial in Block 145 in 2003. In years 4 to 7, selection was conducted based on precocity, fruit size, fruit colour and yield. 'AAC Eversweet' was selected for its exceptional shelf life in maintaining its firmness and sweet flavour.

Tests & Trials: Trials for 'AAC Eversweet' were conducted at the Kentville Research Station of Agriculture and Agri-Food Canada in Kentville, Nova Scotia. Plots consisted of 5 individually standing trees planted in a RCB design, spaced 3 metres apart in the row and 5 metres between the rows. Both the candidate and reference varieties were grafted on MM106 rootstalks. 'AAC Eversweet' was planted in 2009 and the reference varieties were planted in 2005. Observations were completed during the 2012 growing season.
