Origin & Breeding History: '74P00LL' was developed by the University of Guelph, Guelph, Ontario by crossing 'OAC Hurricane' with a Liberty source in September of 2000. The F1 generation was screened for the appropriate herbicide resistance and backcrossed cyclically to 'OAC Hurricane' until the BC3 generation in December of 2001. The BC3's were then used to produce doubled haploids from April 2002 to January 2003. BC937-104LL was selected from amongst 44 other doubled haploid lines.

Tests & Trials: Tests and trials were conducted during the summers of 2006 and 2007 at the Elora Research Station, of the University of Guelph, Elora, Ontario. Plots consisted of 4 rows per variety spaced 20 centimetres apart with a row length of 6 meters. There were two replicates arranged in an RCB design.
