Origin & Breeding History: 'DrisRaspThree' arose from a controlled cross between proprietary lines 'X146.7' (female parent) and 'S858.1' (male parent). Breeding was conducted in Santa Cruz, California in April 2002. 'DrisRaspThree' was selected from the seedling population in October 2003. 'DrisRaspThree' was asexually propagated in Santa Cruz, California and underwent propagation and continued testing for four years. Selection criteria included yield, flavour, and vigour.

Tests & Trials: The comparative trials for 'DrisRaspThree' were conducted in Chilliwack, British Columbia during the 2014 growing season. The plots were planted in the spring of 2013 in a randomized complete block design (RCBD). Each variety consisted of 3 replicates with 5 plants per replicate for a total of 15 plants of each variety. Plants were spaced approximately 61 centimetres apart within rows and 3 metres between rows.
