Origin & Breeding History: 'AAC Evelyn' (experimental designation K13-19) originated from a cross conducted in the winter of 2012 in a greenhouse at the Agriculture & Agri-Food Canada, Kentville Research and Development Centre, Kentville, Nova Scotia. The cross was made between the female parent line K11-19 and the male parent line K09-4. A single plant was selected for asexual propagation via stolons in the summer of 2013 from a seedling field in Sheffields Mills, Kings County, Nova Scotia. 'AAC Evelyn' was selected based on time of ripening, fruit size, and yield potential.

Tests & Trials: The comparative trial for 'AAC Evelyn' was conducted at the Agriculture & Agri-Food Canada, Kentville Research and Development Centre, Kentville, Nova Scotia in a greenhouse in 2021. The plants were grown in individual 15cm pots on wire mesh benches. There were 10 rows of 3 plants for a total of 30 plants per variety. Plants were spaced 30 cm apart with 60 cm spacing between varieties. Measurements were taken from a minimum of 18 plants or parts of 18 plants of each variety. Mean differences were significant at the 5% probability level based on a Student's T-test.
