Origin & Breeding History: 'CDC Sanctuary' was developed by the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan. The cross between 'CDC Bethune' and 'FP2006' was made in the Phytotron of the College of Agriculture in 1998 and the F1 was raised in the Phytotron. 'FP2006' arose from the cross 'Flanders' / 'FP908'. The F2 population was grown at the Kernen Crop Research Farm in 1999 and advanced using the pedigree system from the F3 (2000) through F5 (2002). Selection at each generation was primarily for vigour of stand, maturity, oil concentration and iodine value. From 2003 through 2005, the line was evaluated as F03154 in replicated yield trials in Saskatchewan. It was entered into the Flax Cooperative Test in 2006 as FP2242 and tested through to 2008.
Tests & Trials: Tests and trials were conducted in 2009 and 2010 in Saskatoon, Saskatchewan. Trials consisted of 2 replications of each variety in a randomized complete block design (RCBD). There were 7 rows per replicate with a row length of 3.66 meters with 18 cm between rows (5.2 square meters). The trials were seeded on May 21 and 20 respectively. Measured characteristics were based on 20 measurements.
