Summary: The stolon of 'AAC Kate' has a weak intensity of anthocyanin colouration while the stolon of 'AAC Evelyn' has an absent or very weak intensity of anthocyanin colouration and that of 'AAC Lila' has a strong intensity of anthocyanin colouration. The upper side of the leaf of 'AAC Kate' is dark green while those of 'AAC Lila' and 'Mira' are medium green. The leaf of 'AAC Kate' has strong blistering and medium glossiness while those of the reference varieties have a medium degree of blistering and absent or weak glossiness. The base of the terminal leaflet of 'AAC Kate' is rounded while the base of the terminal leaflet of 'AAC Evelyn' and 'AAC Lila' are obtuse and that of 'Mira' is acute. The flower of 'AAC Kate' is larger in diameter than those of 'Mira' and 'AAC Evelyn'. The calyx of 'AAC Kate' is smaller than the corolla while the calyx of 'Mira' is the same size as the corolla. The fruit of 'AAC Kate' is moderately longer than it is wide while that of 'AAC Evelyn' is much longer than it is wide. The fruit of 'AAC Kate' is ovoid in shape while the fruit of 'Mira' is globose and that of 'AAC Evelyn' and 'AAC Lila' are long conic. The fruit of 'AAC Kate' is medium red while the fruit of 'Mira' is orange red. The fruit of 'AAC Kate' has a narrow band without achenes while the fruit of 'AAC Lila' has a broad band without achenes and the fruit of 'Mira' has a very broad band without achenes. The calyx attachment on the fruit of 'AAC Kate' is positioned level with the fruit while those of the reference varieties are raised. The sepals on the fruit of 'AAC Kate' have an outwards attitude while the sepals of 'AAC Lila' and 'Mira' have an upwards attitude. The adherence of the calyx on the fruit of 'AAC Kate' is very strong while that of the reference varieties is of medium strength.

Origin & Breeding History: 'AAC Kate' (experimental designation K12-14) originated from a cross conducted in the winter of 2011 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 K07-32 and the male parent line K04-21. A single plant was selected for asexual propagation via stolons in the summer of 2012 from a seedling field in Sheffields Mills, Kings County, Nova Scotia. 'AAC Kate' was selected based on time of ripening, fruit size, and fruit flavour.
Tests & Trials: The comparative trial for 'AAC Kate' 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.
