YOUNG SHOOT (during rapid growth): weak intensity of anthocyanin colouration, medium green, many glandular hairs
DORMANT CANE: medium to strong intensity of anthocyanin colouration, many branches distributed over whole length, rounded in cross-section, medium to many medium sized spines with downwards attitude
CURRENT YEAR'S CANE: no fruiting
PETIOLE: small stipules
LEAF: predominantly three and five leaflets, odd-pinnate type, light to medium green on upper side, weak to medium glossiness on upper side
TERMINAL LEAFLET: lobing absent, u-shaped in cross-section, absent or very weak undulation of margin, strong to very strong blistering between veins
LEAFLET: shallow serrate incisions of margin

Origin & Breeding History: 'DrisBlackNineteen' originated from a cross between 'DrisBlackFive', as the female parent, and a proprietary line designated 'BL481.3', as the male parent, conducted in April 2010. 'DrisBlackNineteen' was selected in Los Reyes, Mexico in 2011 on the basis of plant vigor, yield, fruit shelf-life and flavour. 'DrisBlackNineteen' was further propagated by root cuttings and underwent additional testing in Los Reyes, Mexico from 2012 to 2018.
Tests & Trials: The comparative trial for 'DrisBlackNineteen' 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. 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.
