Origin & Breeding History: 'DrisBlueTwentyThree' originated from a controlled cross between the unpatented female parent '196H-3' and the unpatented male parent '75J301' made in February 2011 in Santa Cruz County, California, USA. 'DrisBlueTwentyThree' was selected from the resulting progeny in Hillsborough County, Florida, USA in April 2013 for fruit taste, fruit texture, fruit size, evergreening of the plant and time of harvest. The original seedling of the new variety was propagated by softwood cuttings in Santa Cruz County, California in July 2013. Additional propagation was conducted by softwood cuttings and tissue culture and further testing occurred in Ventura County, California, USA from 2014 to 2019.
Tests & Trials: The comparative trial for 'DrisBlueTwentyThree' was conducted by Expert Agriculture Team Ltd., in Chilliwack, British Columbia, Canada during the 2023 growing season. One year old plants were transplanted in April 2021 into raised beds, covered with plastic mulch 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.
