Variety Description

Variety used for comparison: 'Glenn'

Summary: At the 5 to 9 tiller stage, the plants of 'SY Manness' have a semi erect growth habit while the plants of 'Glenn' have an erect growth habit. At booting, the flag leaf auricles of 'SY Manness' have an absent or very weak intensity of anthocyanin colouration while the flag leaf auricles of 'Glenn' have a strong intensity of anthocyanin colouration. The flag leaf of 'SY Manness' is larger than the flag leaf of 'Glenn'. The plants of 'SY Manness' head later than the plants of 'Glenn'. At heading, the spike of 'SY Manness' has very strong glaucosity while the spike of 'Glenn' has weak glaucosity. The culm neck of 'SY Manness' has strong glaucosity while that of 'Glenn' has medium glaucosity. At maturity, the plants of 'SY Manness' are shorter than the plants of 'Glenn'. At maturity, the spike of 'SY Manness' is white with white awns and has an erect attitude while the spike of 'Glenn' is light brown with light brown awns and has an inclined attitude. The lower glume shoulder of 'SY Manness' is of a medium width and slightly sloping while that of 'Glenn' is broad and elevated. The lower glume of 'SY Manness' is short while the lower glume of 'Glenn' is of a medium length. The lower glume beak of 'SY Manness' is moderately curved while that of 'Glenn' is slightly curved. The kernel weight of 'SY Manness' is less than the kernel weight of 'Glenn'.

Description:

PLANT: spring type, common wheat, semi-erect growth habit at 5 to 9 tiller stage, medium frequency of plants with recurved flag leaves, heads mid-season, matures mid-season

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

CULM: strong glaucosity, curved neck
STRAW: thin pith in cross-section, no anthocyanin colouration at maturity

SPIKE: very strong glaucosity at heading, tapering shape in profile, lax to medium density, white at maturity, erect attitude, absent or very sparse hairiness of convex surface of apical rachis segment
AWNS: shorter than spike, white at maturity
LOWER GLUME: short, medium to broad, glabrous, sparse internal hairs
LOWER GLUME SHOULDER: medium width, slightly sloping
LOWER GLUME BEAK: short to medium in length, moderately curved
LOWEST LEMMA: slightly curved beak

KERNEL: hard red, medium red, small to medium in size, short, narrow to medium width, broad elliptical, rounded cheek, short brush hairs
GERM: medium to large, oval, narrow and deep crease

AGRONOMIC TRAITS: good bread making quality

Origin & Breeding History: 'SY Manness' (experimental designations BW1093 and NH032) originated from a cross between 03S0227-2 and 'Faller' conducted in Berthoud, Colorado in 2008. F2 head selections were made at the Syngenta Seeds breeding nursery in Argusville, North Dakota, USA in 2009 with single seed descent technique used to advance the selections through the F3 and F4 generations in a greenhouse. In 2010, F5 headrows were individually bulked and entered into a spring preliminary yield trial in Argusville, North Dakota in 2011. One of the bulk selections designated 08S0303-16 was entered into Northern Plains Y2 to Y5 Yield Trial from 2012 to 2015 and then entered in Syngenta Canada Inc. multiple location research plots in Canada in 2016. The new variety was tested in the Canadian Northern Hard Red Coop in 2017 as NH032 and then based on milling and baking profile, was entered in the Central Bread Wheat Co-op Trial during the 2018-2019 growing seasons as BW1093. In 2016, F4:12 plots were bulked in Eaton, Colorado to establish breeder seed. Selection criteria included plant maturity, disease resistance, yield, test weight and milling and baking quality.

Tests & Trials: The comparative trials for 'SY Manness' were conducted at the Syngenta Canada Inc., Rosebank Research Farm in Rosebank, Manitoba in 2019 and 2021. There were 3 replicates per variety arranged in an RCB design. Plots consisted of 7 rows, each row was 3.0 metres long with 0.18 metre inter-row spacing. The seeding density was 645 seeds per squared metre, resulting in approximately 7200 plants per variety per year. Measured characteristics were based on a minimum of 20 measurements per variety per year. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
