Variety Description

Varieties used for comparison: 'Vesper', 'Superb', 'Unity' and 'Waskada'

Summary: The intensity of anthocyanin colouration of the coleoptile of 'BW410' is absent or very weak while it is medium in 'Superb' and 'Waskada' but strong in 'Unity'. 'BW410' has absent or very weak intensity of anthocyanin colouration of the auricles of the flag leaf while it is weak to medium in 'Vesper', Superb' and 'Waskada'. At heading, the spike of 'BW410' has medium to strong glaucosity while it is weak to medium in 'Unity'. The spike of 'BW410' is shorter than 'Vesper'. 'BW410' has a lower glume shoulder shape that is slightly sloping to straight while it is straight to elevated in 'Unity'. The lower glume of 'BW410' is pubescent while it is glabrous for 'Vesper', 'Superb' and 'Waskada'. 'BW410' has a short beak of the lower glume while it is medium length for 'Superb'. 'BW410' matures later than 'Unity'. At maturity, the straw of 'BW410' has no anthocyanin colouration while in 'Unity' it does. 'BW410' has better pre-harvest sprouting resistance than 'Vesper'. 'BW410' is susceptible to wheat midge while 'Vesper' and 'Unity' are resistant and 'Waskada' is moderately resistant.

Description:

PLANT: spring type, common wheat, semi-erect growth habit at the 5-9 tiller stage, weak to medium glaucosity of the culm at heading, medium to high frequency of plants with recurved flag leaves

SEEDLING (4 leaf stage): absent or very weak intensity of anthocyanin colouration of the coleoptile, glabrous sheaths and blades of the lower leaves

FLAG LEAF: absent or very weak intensity of anthocyanin colouration of the auricles, medium glaucosity of the sheath, glabrous blade and sheath

STRAW (AT MATURITY): thin pith in cross-section, no anthocyanin colouration
SPIKE: medium to strong glaucosity at heading, parallel to semi-clavate profile, medium density, awns present, awns shorter than the length of the spike
SPIKE AT MATURITY: white, whitish awns, erect attitude, very sparse to sparse hairiness of convex surface of apical rachis segment
LOWER GLUME: narrow to medium width shoulder, slightly sloping to straight shoulder shape, medium length, narrow to medium width, pubescent, short slightly curved beak, very sparse to sparse extent of internal hairs
LOWEST LEMMA: slightly curved beak

KERNEL: hard red type, medium red colour, small to medium size, medium length, medium width, ovate, rounded cheek shape, medium to long brush hairs, medium to large sized round to oval germ, narrow crease width, medium crease depth

AGRONOMY: good resistance to shattering, good resistance to pre-harvest sprouting

QUALITY: good bread making

DISEASE REACTION: resistant to Leaf rust (Puccinia triticina), Stem rust (Puccinia graminis f. sp. tritici) and Loose smut (Ustilago tritici), moderately resistant to Fusarium head blight (Fusarium graminearum) and Common bunt (Tilletia caries, Tilletia foetida)

PEST REACTION: susceptible to wheat midge (Sitodiplosis mosellana)

Origin & Breeding History: 'BW410' (99B51-EZ2B) derives from the cross McKenzie // BW257 / 94B92-Y3B that was made in 1999 at the Cereal Research Centre, AAFC, Winnipeg, Manitoba. McKenzie derives from Columbus / Amidon. 94B92-Y3B derives from 90B01-F3C / AC Domain and 90B01-F3C derives from AC Minto*2 / ND643. Spike selections were made at the F2, F3 and F6 generations following observations of agronomic type and disease resistance. Following 2 years of testing in multi-location yield trials in 2005 and 2006, 99B51-EZ2B was entered as BW410 into the Central Bread Wheat Coop Trials in 2007.

Tests & Trials: Tests and trials were conducted during the summers of 2009 and 2010 in Portage la Prairie, Manitoba. Plots consisted of 5 rows with a row length of 4.3 meters and a row spacing of 23 cm. There were 4 replicates arranged in a RCB design.
