Origin & Breeding History: 'DrisRaspFourteen' originated from a controlled cross conducted between the unpatented proprietary varieties 'RB629.4' (female parent) and 'Y454.3' (male parent) in Santa Cruz County, California, USA in April 2009. A single seedling of 'DrisRaspFourteen' was selected in March 2011 in Ventura County, California, USA based on its primocane and floricane yield, fruit size, and fruit flavor. 'DrisRaspFourteen' was initially asexually propagated by root cutttings in May 2011. Further propagation and testing continued in Ventura County, California from 2010 to 2018.

Tests & Trials: The comparative trial for 'DrisRaspFourteen' was conducted in Chilliwack, British Columbia during the 2021 growing season. Plants were transplanted in October of 2020 into raised beds, covered with plastic mulch and irrigated with drip lines. The plots were arranged in a RCB design with four 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 and 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.
