Origin & Breeding History: 'CDC Neela' (experimental designations FP2314, F07085) was developed at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan using a pedigree breeding method. The cross between 'CDC Mons' and 'CDC Sorrel' was conducted in 2001 in the growth chamber at the College of Agriculture and BioResources, University of Saskatchewan. The F2 population was grown at the Kernen Crop Research Farm in 2002 and advanced using the pedigree system from the F3 through F5. Selection at each generation was primarily for vigour of stand, maturity, oil content and iodine value. From 2007 through 2009, the line was evaluated as F07085 in replicated yield trials in Saskatchewan. In 2010 and 2011, it was entered and tested in the Flax Cooperative Test as FP2314.
Tests & Trials: Tests and trials were conducted in 2012 and 2013 in Saskatoon, Saskatchewan. Trials consisted of 3 replications of each variety in a randomized complete block design (RCBD). There were 6 rows per replicate with a row length of 3.66 metres with 18 cm between rows. Measured characteristics were based on 20 measurements each year.
