Origin & Breeding History: 'SP Force CL' (NO01-5815) is the result of a cross made by the breeder Daryl Males of Saskatchewan Wheat Pool Inc., Saskatoon, Saskatchewan in 2001. An F1 plant derived from the cross was used as a donor plant to produce microspore derived doubled haploids in 2001. From this population of doubled haploids one doubled haploid line was selected based on resistance to Odyssey. Subsequent selection criteria included maturity, lodging resistance, seed quality characteristics, yield and disease resistance. Yield trials were conducted in 2003, 2004 and 2005. Concurrent to yield trials, field trials were conducted for herbicide resistance. Disease testing for blackleg and white rust were conducted 2004 and 2005. Fusarium wilt disease testing was also conducted in 2004.

Tests & Trials: Tests and trials for 'SP Force CL' were conducted in the summers of 2005 and 2006 in Rosthern, Saskatchewan. Plots consisted of 6 rows, 5.5 meters in length with a row spacing of 20 cm. There were 4 replicates arranged in a Random Complete Block Design.
