Summary: Vegetative bud burst on the previous season's canes of 'DrisRaspFourteen' occurs early in the season while it occurs late season for 'DrisRaspThirteen' and very late season for 'DrisRaspEight'. The emergence of the current season's canes occurs early in the season for 'DrisRaspFourteen' while it occurs mid-season for 'DrisRaspThirteen' and late season for 'DrisRaspEight'. The plants of 'DrisRaspFourteen' have many current season's canes whereas those of 'DrisRaspThirteen' have a medium number and those of 'DrisRaspEight' have few to a medium number. Both the previous and current season's canes of 'DrisRaspFourteen' are longer than those of the reference varieties. The density of spines on 'DrisRaspFourteen' is sparse whereas it is dense on 'DrisRaspThirteen' and of medium density on 'DrisRaspEight'. Flowering on the current season's canes of 'DrisRaspFourteen' begins early in the season while it begins mid to late season for 'DrisRaspThirteen' and very late season for 'DrisRaspEight'. 'DrisRaspFourteen' has a small flower whereas that of 'DrisRaspThirteen' is medium sized and that of 'DrisRaspEight' is medium to large. The fruit of 'DrisRaspFourteen' is medium to long whereas that of 'DrisRaspThirteen' is short to medium and that of 'DrisRaspEight' is short. The fruit of 'DrisRaspFourteen' has a medium red colour whereas the fruit of the reference varieties have a dark red colour. Fruit ripening on the current season's canes of 'DrisRaspFourteen' begins very early to early in the season while it begins late in the season for 'DrisRaspThirteen' and very late in the season for 'DrisRaspEight'.

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.
