Origin & Breeding History: 'Toki' originated from the cross Ken Feng/AC Proteus(X3153-B-B-1-8)*2/2/Tamba Black, made by the Eastern Cereal and Oilseed Research Centre, Agriculture & Agri-Food Canada, Ottawa, Ontario. The F2 population was grown in Ottawa in 1994. Pedigree selection was employed through the F5 generation. In the F5 generation, selected progeny rows were bulked for evaluation in following generations. 'Toki' was tested as X3790-11-5-1 in Ottawa in 1998 and 1999 and tested as OT02-16 at multiple locations in Ontario and Quebec from 2000 to 2004.
Tests & Trials: Trials for 'Toki' were conducted in 2005 and 2006 at the Eastern Cereal and Oilseed Research Centre, Agriculture & Agri-Food Canada, Ottawa, Ontario. The trials consisted of four replications with four rows per replication. Plots were approximately 1.6 x 5 metres and were arranged in a randomized complete block design.
