Origin & Breeding History: 'HY116-SRW' (experimental designation 'TWF116-072') is a winter wheat variety bred and developed by Hyland Seeds Inc. 'HY116-SRW' derives from the cross made in 1996 of WF042 (P2510 // Freedom / FHB148) / Freedom at Ailsa Craig, Ontario. The doubled haploid method with maize hybridization was used to breed this variety at the F1 generation. The Y2 was planted in the fall of 2000, and selected in 2001 on the basis of yield, seed and test weight. 'HY116-SRW' was entered into a 2-replicate trial in the fall of 2001 to 2005 where it was evaluated for yield. It was entered into the Orthogonal Soft Wheat Trial in Ontario in 2005 and 2006.

Tests & Trials: Tests and trials were conducted in 2009 and 2010 at Nairn, Ontario. Plots consisted of 5 rows with a row length of 4 meters and a row spacing 20 cm. Plots were seeded at a rate of 400 seeds per meter squared. There were 4 replicates arranged in a RCB design.
