Origin & Breeding History: 'BC92641' is the result of a cross made in 1992 between 'Chilliwack' and 'BC86-41-15' at the PARC-Abbotsford Substation, British Columbia. The parentage includes 'BC64-10-198', Skeena, and a wild raspberry R. strigosus, clone collected from Québec which has a high level of resistance to root rot. The selection criteria used were fruit appearance, taste, flesh texture, harvest time, plant quality, productivity, precocity, and disease resistance.

Tests & Trials: Trials for 'BC92641' were conducted at the Pacific Agri-Food Research Centre, Abbotsford Substation, British Columbia during 2009 and 2010. The trial included 25 plants per variety separated into 3 replication plots. Plots were 3 metres long rows with a plant spacing of 0.9 metres between plants and 3 metres between the rows.
