Origin & Breeding History: 'DrisBlackFive' is the result of a cross between 'BG837-2' (female parent) and 'BH917-6' (male parent) conducted in April 2003 in Santa Cruz County, California, USA. 'DrisBlackFive' was selected for its fruit size and plant vigour. 'DrisBlackFive' was further propagated and underwent additional testing in Los Reyes, Mexico from 2007 to 2010.
Tests & Trials: The comparative trial for 'DrisBlackFive' was conducted in Chilliwack, British Columbia during the 2018 growing season. The plots were arranged in a randomized complete block design. Each variety was planted in 3 replicates with 3 plants per replicate for a total of 9 plants of each variety. Plants were spaced approximately 1.07 metres apart. Measurements were taken from 9 plants or parts of 9 plants of each variety. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
