Variety Description
Varieties used for comparison: 'Maravilla' and 'DrisRaspSeven' (Esperanza)
Summary: During rapid growth, the apex of the very young shoot of 'DrisRaspEighteen' has no anthocyanin colouration whereas both reference varieties have anthocyanin colouration. The current season cane of 'DrisRaspEighteen' has long internode length whereas 'Maravilla' has short to medium internode length. The current season's cane of 'DrisRaspEighteen' has a sparse arrangement of spines whereas 'DrisRaspSeven' has a dense arrangement of spines. The rugosity of the leaf of 'DrisRaspEighteen' is medium whereas that of 'Maravilla' is strong and that of 'DrisRaspSeven' is weak. The terminal leaflet of 'DrisRaspEighteen' is smaller than the terminal leaflet of both reference varieties. The fruit of 'DrisRaspEighteen' is of narrow to medium width whereas the fruit of both reference varieties is medium to broad.

Origin & Breeding History: 'DrisRaspEighteen' originated from a controlled cross conducted between 'DrisRaspTwelve' (female parent) and 'DrisRaspThirteen' (male parent) in Santa Cruz County, California, USA in April 2013. A single seedling of 'DrisRaspEighteen' was selected in October 2015 based on yield and fruit flavour. 'DrisRaspEighteen' was further propagated by root cuttings from 2015 to2019 in Santa Cruz County, California, USA.
Tests & Trials: The comparative trial for 'DrisRaspEighteen' was conducted in Chilliwack, British Columbia during the 2022 growing season. Plants were transplanted in April 2021 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. A total of 20 measurements were taken from each variety. Mean differences were significant at the 5% confidence probability level based on a paired Student`s t-test.
