Variety Description
Varieties used for comparison: 'Maravilla' and 'DrisRaspSeven' (Esperanza)
Summary: On the current season's cane, the density of spines on 'DrisRaspTwentyTwo' is medium whereas it is sparse on 'Maravilla' and dense on 'DrisRaspSeven'. The current season's cane of 'DrisRaspTwentyTwo' has spines with a very small base whereas that of 'DrisRaspSeven' has spines with a medium sized base. The leaf of 'DrisRaspTwentyTwo' has a weak to medium degree of rugosity whereas the leaf of 'Maravilla' has strong rugosity. The terminal leaflet of 'DrisRaspTwentyTwo' is smaller than the terminal leaf of both reference varieties. The attitude of the fruiting lateral on the previous season's cane for 'DrisRaspTwentyTwo' is erect whereas that of both reference varieties is semi-erect.
Description:

Origin & Breeding History: 'DrisRaspTwentyTwo' originated from a controlled cross conducted between the proprietary line 'RJ0760.1' (female parent) and 'DrisRaspTwelve' (male parent) in Santa Cruz County, California, USA in April 2013. A single seedling of 'DrisRaspTwentyTwo' was selected in May 2016 based on yield and fruit size. 'DrisRaspTwentyTwo' was further propagated by root cuttings from 2016 to 2019 in Santa Cruz County, California, USA.
Tests & Trials: The comparative trial for 'DrisRaspTwentyTwo' 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.
