Varieties used for comparison: 'Heritage' and 'Autumn Britten'
Summary: On the current season's cane, the spines on 'DrisRaspTwo' are long whereas on 'Heritage' the spines are medium length. The terminal leaflet of 'DrisRaspTwo' is shorter than that of both reference varieties. The terminal leaflet of 'DrisRaspTwo' is narrower than that of 'Autumn Britten'. The pedicel of 'DrisRaspTwo' has a medium number of spines whereas that of 'Autumn Britten' has many to very many. The intensity of anthocyanin colouration on the peduncle of 'DrisRaspTwo' is very weak to weak whereas that of 'Heritage' is strong and that of 'Autumn Britten' is strong to very strong. On the previous year's cane, the fruiting lateral of 'DrisRaspTwo' is longer than those of the reference varieties. On the current season's cane, flowering and fruit ripening begin later in the season for 'DrisRaspTwo' whereas they begin mid-season for 'Heritage'.
PLANT: upright growth habit, bears fruit on both previous season's cane in summer and on current season's cane in autumn

Origin & Breeding History: 'DrisRaspTwo' arose from a controlled cross between 'Driscoll Cardinal' (female parent) and 'W776.1' (proprietary male parent). Breeding was conducted in Santa Cruz, California in 2004. 'DrisRaspTwo' was selected from the seedling population in September 2004. 'DrisRaspTwo' was asexually propagated at Driscoll Nursery in Santa Cruz, California and underwent further propagation and continued testing from 2005 to 2009. Selection criteria included early production season, high yield and shelf life.
Tests & Trials: The comparative trials for 'DrisRaspTwo' 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.
