The dormant cane of 'DrisBlackTwentyFour' has a medium number of large spines while those of the reference varieties have no spines. The leaf of 'DrisBlackTwentyFour' has predominantly five leaflets while those of the reference varieties have predominantly three leaflets. The leaf of 'DrisBlackTwentyFour' is odd-pinnate type while that of 'DrisBlackTwelve' is palmate type. The flower of 'DrisBlackTwentyFour' is white while the flower of 'DrisBlackThirteen' is pinkish. The fruit of 'DrisBlackTwentyFour' has a small length to width ratio while the length to width ratio is large for the fruit of the reference varieties. The time of flowering on the previous year`s canes begins very early for 'DrisBlackTwentyFour' while it begins late in the season for 'DrisBlackTwelve'. The time of fruit ripening on the previous year`s canes begins early in the season for 'DrisBlackTwentyFour' while it begins late in the season for 'DrisBlackTwelve'.

Origin & Breeding History: 'DrisBlackTwentyFour' originated from a cross, between the proprietary line designated, 'BQ948.1', as the female parent, and 'DrisBlackThirteen', as the male parent, conducted in April 2011 in Santa Cruz County, California, USA. 'DrisBlackTwentyFour' was selected in 2013 on the basis of plant health, plant vigor, fruit size, fruit firmness and flavour. 'DrisBlackTwentyFour' was further propagated by root cuttings and underwent additional testing in Santa Cruz County, California from 2015 to 2019.
Tests & Trials: The comparative trial for 'DrisBlackTwentyFour' was conducted in Chilliwack, British Columbia during the 2021 growing season with dormant cane traits being assessed late in the fall of 2020. There were four replicates per variety, arranged in a randomized complete block design. Each replicate consisted of 3 plants in a 2.7 metre row for a total of 12 plants per variety. Plants were spaced approximately 0.91 metres apart within the row with 3 metre inter-row spacing. Observations were taken from 10 plants or parts of 10 plants of each variety.
