The fruit of 'VACSID15' has low sweetness whereas the fruit of 'Duke' has medium to high sweetness. The fruit of 'VACSID15' has very high acidity whereas the fruit of 'Duke' has low to medium acidity and 'Reka' has medium to high acidity. Flowering on one-year-old shoots of 'VACSID15' begins early to mid-season whereas flowering begins very early for 'Reka'.


PLANT: strong vigour, upright growth habit, flowers and fruits on one-year-old shoots only, flowering begins early to mid-season, fruit ripening begins early season
ONE-YEAR-OLD SHOOT: greenish red, medium to long internode length

LEAF: medium length to width ratio, elliptic shape, dark green on upper side, entire margin

COROLLA: urceolate shape
CORROLA TUBE: medium to large with ridges, weak intensity of anthocyanin colouration

FRUIT: medium density fruit cluster, medium to dark intensity of green on unripe fruit, medium to large, oblate shape in longitudinal section, sepals reflexed with erect to semi-erect attitude, deep calyx basin, medium bloom intensity, dark blue skin, firm, low sweetness, very high acidity

Origin & Breeding History: 'VACSID15' arose from an open pollinated cross between 'Reka' (female parent) and 'Duke' (male parent) made in 2004 in Mission, BC, Canada. From the resulting progeny, 'VACSID15' was selected in 2008 for its vigour, fruit abundance and firmness.

Tests & Trials: The comparative trials for 'VACSID15' were conducted by Expert Agriculture Team Ltd., in Chilliwack, British Columbia during the 2015 growing season. The plots were planted in the spring of 2014 in a randomized complete block design. Each variety consisted of 2 replicates with 3 plants per replicate for a total of 6 plants of each variety. Plants were spaced approximately 60 centimetres apart within rows and 3 metres between rows. Measurements were taken from 6 plants or parts of plants of each variety. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
