Origin & Breeding History: 'S14-L9' (experimental designation AR0902412) originates from the cross 22875/43379 conducted in 2006 in Arva, Ontario. Seed was bulk harvested in the fall of 2006. Using the single seed descent method, the F2-F3 were grown in a winter contra season nursery. In the summer of 2007, single plants were selected from the F4, with the F5 being grown out in single replicated trials during the 2008 growing season. The F6 was grown out in a multiple location yield trial in the summer of 2009 and bulk planted in winter contra season plots. The F7 to F10 were evaluated in wide area testing during the 2010 to 2012 growing seasons. Selection criteria included yield performance, disease resistances and quality characteristics.

Tests & Trials: Tests and trials were conducted at Syngenta Canada, Inc., Arva, Ontario during the 2012 and 2013 growing seasons. The plots consisted of 2 replicates per variety containing 2 rows per replicate with a row length of 5 meters and a row spacing of 0.75 meters.
