Variety Description
Varieties used for comparison: 'DrisBlueOne' and 'DrisBlueSeven'
Summary: The plants of 'DrisBlueSixteen' have very strong vigour whereas the plants of the reference varieties have medium to strong vigour. The plants of 'DrisBlueSixteen' have an upright growth habit whereas the plants of 'DrisBlueSeven' have a semi-upright growth habit. The leaf of 'DrisBlueSixteen' is larger than the leaf of both reference varieties. The leaf of 'DrisBlueSixteen' is lanceolate in shape whereas it is elliptic for 'DrisBlueOne'. Flowering on one-year-old shoots begins mid-season for 'DrisBlueSixteen' whereas it begins late season for 'DrisBlueSeven' and very late in the season for 'DrisBlueOne'. Excluding the peduncle, the inflorescence of 'DrisBlueSixteen' is longer than that of 'DrisBlueOne'. The anthocyanin colouration on the outer side of the corolla tube of 'DrisBlueSixteen' is of a medium intensity whereas it is absent or very weak for the reference varieties. The bloom on fruit of 'DrisBlueSixteen' is of a weak to medium intensity whereas the intensity of the bloom is strong on the fruit of 'DrisBlueOne'. Fruit ripening on one-year-old shoots begins early in the season for 'DrisBlueSixteen' whereas it begins mid-season for 'DrisBlueOne'.

Origin & Breeding History: 'DrisBlueSixteen' originated from a cross between the proprietary varieties '127D 2', as the female parent, and 'DrisBlueOne', as the male parent, made in 2005 in Santa Cruz County, California, USA. 'DrisBlueSixteen' was selected from the resulting progeny in 2009 in Santa Cruz County, California, USA for its flowering and fruiting time on current season's shoots, fruit size, fruit flavor and plant growth habit. Subsequent asexual propagation by softwood cuttings took place in Santa Cruz County, California, USA. Further testing was conducted in Santa Cruz County and Ventura County, California from 2009 to 2017.
Tests & Trials: The comparative trial for 'DrisBlueSixteen' was conducted by Expert Agriculture Team Ltd., in Chilliwack, British Columbia, Canada during the 2021 growing season. One-year-old plants were transplanted in October 2019 into raised beds, covered with plastic and drip irrigated with drip lines. The plots were arranged in an RBC design with 4 replicates. Each replicate consisted of 3 plants for a total of 12 plants of each variety. Plants were spaced approximately 90 centimetres apart within rows with 3 metres between rows. Measurements were taken from 10 plants or parts of 10 plants of each variety. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
