Origin & Breeding History: 'DrisBlueNineteen' originated from a cross between the proprietary varieties 'DrisBlueSeven', as the female parent, and '193C 4', as the male parent, made in February 2009 in Santa Cruz County, California, USA. 'DrisBlueNineteen' was selected from the resulting progeny in 2011 in Hillsborough County, Florida, USA as an early-season evergreen with no apparent chilling requirement and for its fruit volume and fruit quality. Subsequent asexual propagation by softwood cuttings and tissue culture took place in Santa Cruz County, California, USA. Further testing in both Santa Cruz County, California and Hillsborough County, Florida was conducted from 2013 to 2017.
Tests & Trials: The comparative trial for 'DrisBlueNineteen' 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 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.
