The lower glume beak of 'Daybreak' is long to very long whereas the lower glume beak of 'Glenn' is short and that of 'AAC Brandon' is medium in length. The kernel of 'Daybreak' is medium red while the kernel of 'AAC Brandon' is dark red.

Description:

PLANT: spring type, common wheat, semi-erect growth habit at 5 to 9 tiller stage, heads mid-season, matures mid-season

FLAG LEAF: medium degree of glaucosity of sheath at heading

STRAW (AT MATURITY): thin pith in cross-section

SPIKE: weak to medium glaucosity at heading, tapering to parallel sided shape in profile, medium density, white at maturity
AWNS: shorter than spike length
LOWER GLUME: long, medium to wide, glabrous
LOWER GLUME SHOULDER: straight to elevated, narrow to medium width
LOWER GLUME BEAK: long to very long, slightly curved

KERNEL: hard red type, medium red, medium in size, oval

Origin & Breeding History: 'Daybreak' (experimental designation LNR13-0601 and BW5056) was developed using a modified bulk breeding method. In 2010, a cross was conducted between proprietary lines in Northfield, Colorado, USA with the resulting F1 grown in Fort Collins, Colorado. From 2011 to 2013, the line was advanced from the F2 to the F4 generation with F5 selections grown as head rows for seed stock in Yuma, Arizona during the 2012-2013 growing season. Pre-breeder seed production commenced in Minnesota, USA, in 2016. The variety was concurrently evaluated in mutiple locations across the USA and Canada from 2014 to 2016 and was entered in the Western Bread Wheat Cooperative Registration Trials as BW5056 from 2017 to 2018. 'Daybreak' was selected based on grain yield and stability, maturity, lodging resistance, plant height and disease resistance as well as end use quality traits such as protein content, milling performance, starch quality, gluten strength, gluten extensibility, baking and pasta quality.

Tests & Trials: The comparative trials for 'Daybreak' were conducted at Limagrain Cereals Research Canada in Saskatoon, Saskatchewan during the 2020 and 2021 growing seasons. There were a minimum of 3 replicates per variety in each year, arranged in an RCB design. Each plot was 4.5 square metres and consisted of 6 rows, 3.0 metres in length with 0.22 metre row spacing. The seeding density resulted in 250 plants per square metre, resulting in a minimum of 3,375 plants per variety per year.
