Summary: The flag leaves of 'HY412-SRW' are wider than those of the reference varieties. The plants of 'HY412-SRW' are later heading than those of the reference varieties. The spikes of 'HY412-SRW' are longer than those of the reference varieties. The spike attitude of 'HY412-SRW' inclined whereas it is nodding on 'Branson'. The lower glume of 'HY412-SRW' is medium width and length whereas it is narrow and long on 'Branson'. The width of the kernel crease of 'HY412-SRW' is narrow whereas it is medium on 'Emmit'. The depth of the kernel crease of 'HY412-SRW' is shallow whereas it is mid-deep on both reference varieties.

QUALITY CHARACTERISTICS: fair to good pastry and biscuit quality
DISEASE REACTION: moderately resistant to Septoria tritici blotch (Septoria tritici), moderately resistant to moderately susceptible to Fusarium head blight (Fusarium graminearum, Fusarium species; based on inoculation trials conducted at the Nairn Research Facility in Ailsa Craig, Ontario) and Leaf rust (Puccinia triticina), resistant to Barley Yellow Dwarf virus (6-LOC)

Origin & Breeding History: 'HY412-SRW' (experimental designations TW412-011 and DANW1001) is derived from the cross between 'TW006-007// 'Emmit' (TW044-094) made in the lab at the Nairn Research Facility, Ailsa Craig, Ontario in 2002-2003. The F1 seed was planted in the lab in 2003 and was doubled using the doubled haploid (maize pollinated) method. The F2 was planted as a single 1.8 metre row into the nursery in the fall of 2004 and selected in the summer of 2005 for appearance and disease tolerances. TW412-011 was entered into a two-replicate trial in the fall of 2005 and subsequent internal yield evaluations through 2008. TW412-011 was tested for two years in the Orthogonal Soft Wheat Trial (OCCC) during the 2008-2009 and 2009-2010 growing seasons.

Tests & Trials: Test and trials for 'HY412-SRW' were conducted during the 2012 and 2013 growing seasons at the Nairn Research Facility, Ailsa Craig, Ontario. Plot size was 4.14 metres squared and consisted of 6 rows. The row length was 3.0 metres with 18 cm spacing between rows. There were 4 replicates in an RCB Design. Measured characteristics were based on 20 measurements per variety per year.
