Variety Description

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

Summary: The flag leaves of 'HY419-SRW' are narrower than those of 'Emmit'. The plants of 'HY419-SRW', on average, head two days later than 'Branson'. The culm of 'HY419-SRW' has weak glaucosity whereas it is medium on 'Emmit'. The plants of 'HY419-SRW' are taller than those of 'Branson'. The spikes of 'HY419-SRW' are shorter than those of 'Emmit'.

Description:

PLANT: soft red winter type, erect to semi-erect growth habit at the 5 to 9 tiller stage, heads emerge mid-season, matures mid-season

SEEDLING: absent or very weak intensity of anthocyanin colouration of coleoptile, weak density of pubescence on lower leaf sheaths, very weak density of pubescence on lower leaf blades

FLAG LEAF: low frequency of plants with recurved/drooping flag leaves, absent or very weak anthocyanin colouration of auricles, medium to strong glaucosity of sheath, glabrous blade and sheath

CULM NECK: weak glaucosity, very weak to weak curvature
STRAW: thin pith in cross section, no anthocyanin colouration at maturity
SPIKE: medium glaucosity, tapering to parallel-sided shape, medium density, cream colour at maturity, incline to nodding attitude, medium density of hairiness on convex surface of apical rachis segment
AWNS: very short to short awnlets, white, spreading attitude
LOWER GLUME: narrow to medium width, medium length, sparse pubescence, medium to dense internal hair
LOWER GLUME SHOULDER: narrow to medium width, slightly sloping

GERM: medium size, round to oval shape

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

Origin & Breeding History: 'HY419-SRW' (experimental designations TW419-052 and DANW1002) is derived from the cross 'Emmit' (TW044-094)/TW005-008 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 in the nursery in the fall of 2004 and selected in the summer of 2005 for appearance and disease tolerances. TW419-052 was entered into a two-replicate trial in the fall of 2005 and subsequent internal yield evaluations through 2010. TW419-052 was tested for two years in the Orthogonal Soft Wheat Trial (OCCC) during the 2009-2010 and 2010-2011 growing seasons.

Tests & Trials: Test and trials for 'HY419-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.
