Variety Description

Varieties used for comparison: 'Emmit' and 'Branson'

Summary: The pubescence of the lower leaves at the 4 leaf stage for 'HY116-SRW' is sparse to medium while it is absent or very sparse for 'Branson'. 'HY116-SRW' has a flag leaf that is longer than the reference varieties and wider than 'Branson'. The anthocyanin colouration of the auricles of the flag leaf in 'HY116-SRW' is absent or very weak while it is medium for 'Emmit'. 'HY116-SRW' heads later than 'Branson'. The plant height of 'HY116-SRW' is taller than 'Branson'. 'HY116-SRW' has a strong to very strong glaucosity of the neck of the culm while it is medium in 'Branson'. 'HY116-SRW' has a strong glaucosity of the spike while it is absent or very weak in 'Branson'. At maturity, the spike attitude of 'HY116-SRW' is incline while it is erect in 'Branson'. 'HY116-SRW' has a shorter spike than 'Emmit'. The lower glume of 'HY116-SRW' has a medium width while it is narrow in 'Branson'. 'HY116-SRW' has a moderately curved beak of the lower glume while it is straight in 'Branson' and slightly curved in 'Emmit'. The lower glume of 'HY116-SRW' has sparse internal hairs while it is moderate in 'Emmit'. 'HY116-SRW' has a medium width kernel while it is narrow in 'Branson'. The width of the kernel crease in 'HY116-SRW' is medium while it is narrow in 'Branson'.

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.
