Origin & Breeding History: 'Autumn Britten' is the result of a controlled cross made in 1974 between 'EM 2806/86' and 'EM 2335/47'. The parentage includes Rubus strigosus Michx., R. arcticus L., R. occidentalis L., and the red raspberry varieties 'Malling Landmark', 'Malling Promise', 'Lloyd George', 'Pyne's Royal', 'Burnetholm' and 'Norfolk Giant'. 'Autumn Britten' was grown at Horticultural Research International in East Malling, United Kingdom and selected in 1976 based on its early fall fruiting, large fruit size and good fruit colour. Initial trials were conducted at the National Fruit Trials in Brogden, United Kingdom form 1977 to 1983. Material was sent to Agriculture and Agri-Food Canada's Research Station in Kentville, Nova Scotia in 1980 and it's Pacific Agriculture Research Centre in Vancouver, British Columbia in 1983. Trials were also conducted at the Horticultural Research Institute of Ontario's Horticultural Experiment Station in Simcoe, Ontario from 1987 to 1991.

Tests & Trials: Trials for 'Autumn Britten' were conducted in 2006 at the University of Guelph's Department of Plant Agriculture - Simcoe Campus in Simcoe, Ontario. The trial included 25 plants of the candidate variety and 23 plants of the reference variety. Each plant was grown in a 21.5 cm pot filled with a commercial soil-less mix and grown in a greenhouse. The pots were spaced 30 cm apart and the canes were hand tied to overhead support wires.
