Origin & Breeding History: 'Blackcomb' originated from a cross between the variety 'Ojebyn' and the variety 'Titania', made in 2002 at the farm of McGinnis Berry Crops Limited in Courtney, British Columbia. In 2003, a single seedling was selected for further evaluation at the McGinnis Berry Crops Limited farm in Courtenay, British Columbia and later selected for replicated trials in 2005. 'Blackcomb' was propagated vegetatively from hardwood cuttings and planted as cuttings in Chilliwack, British Columbia at the nursery of Expert Agriculture Team and evaluated from 2006 and 2008. 'Blackcomb' was selected for its resistance to White Pine Blister Rust, long racemes, upright growth habit and vigour.

Tests & Trials: The comparative trial of 'Blackcomb' was conducted in Saanichton, British Columbia in 2015. The trial consisted of a minimum of six plants per variety, spaced 60 cm apart in the row with a spacing of 3 metres between rows.
