Origin & Breeding History: 'AAC Edward' originated from the cross OT99-13 / OT02-18 / 2 / 90A01, conducted in 2003 at the Agriculture & Agri-Food Canada, Ottawa Research and Development Centre, Ottawa, Ontario. The F2 population was grown in Ottawa in 2004 and was advanced using the pedigree selection method. In 2007, selected F5 rows were grown in the field and bulked for further evaluation. 'AAC Edward' was tested as OT11-01 in Ottawa in 2008 and tested at multiple locations since 2009. Selection criteria included early maturity and agronomic characteristics.
Tests & Trials: The comparative trials for 'AAC Edward' were conducted in 2015 and 2016 at the Agriculture & Agri-Food Canada, Ottawa Research and Development Centre, Ottawa, Ontario. The trials consisted of four replicates per variety with four rows per replication. Plots were approximately 1.6 by 5 metres and were arranged in a randomized complete block design. Mean differences were significant at the 5% probability level based on LSD values.
