Origin & Breeding History: 'DrisBlueNine' arose from a cross between proprietary varieties 'MS122' (female parent) and 'G292' (male parent) made in 2003 in Clackamas County, Oregon. From the resulting progeny, 'DrisBlueNine' was selected in 2004 for its large firm fruit.
Tests & Trials: The comparative trials for 'DrisBlueNine' 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 3 replicates with 3 plants per replicate for a total of 9 plants of each variety. Plants were spaced approximately 60 centimetres apart within rows and 3 metres between rows. Measurements were taken from 9 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.
