Wheat

Variety Description

Varieties used for comparison: 'AAC Brandon' and 'LCS Canon'

Summary: The plants of 'Fierce' begin heading later than the plants of 'LCS Cannon'. The lower glume shoulder of 'Fierce' is absent or very narrow to narrow while that of 'AAC Brandon' is of a medium width

Description:

PLANT: common wheat, spring type, semi-erect to intermediate growth habit at the 5 to 9 tiller stage

FLAG LEAF: medium glaucosity of sheath, pubescent blade and sheath

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

SPIKE: medium to strong glaucosity at heading, tapering shape in profile, medium density, white at maturity, awns present
AWNS: longer than the length of spike, light brown

LOWER GLUME SHOULDER: absent or very narrow to narrow, sloping to slightly sloping
LOWER GLUME BEAK: straight to slightly curved

KERNEL: light red

Origin & Breeding History: 'Fierce' (experimental designations LAR20-25760) originated by crossing the F1 of 'CDC Landmark' and 'AAC Viewfield' as the female parent with 'LCS Cannon' as the male parent. The initial cross was conducted in 2017 at Limagrain Cereals Research Canada Centre in Saskatoon, Saskatchewan. From 2017 to 2019, the variety was advanced in the field and in greenhouse to the F4 generation in Saskatoon, Saskatchewan. The F5 generation was grown as fixed lines in Argentina from 2019 to 2020. From 2020 to 2023, the variety was advanced to the F9 generation in the group Limagrain North American breeding network. Across multiple sites in Western Canada and the Northern Plains of the USA, the variety underwent selection based on yield, maturity, lodging resistance, height, disease resistance as well as end use traits such as milling and baking performance. 'LAR20-25760' was identified in 2020 and breeder seed was established from F9 lines in 2023.

Tests & Trials: The comparative trials for 'Fierce' were conducted at Limagrain Cereals Research Canada in Osler, Saskatchewan during the 2022 and 2024 growing seasons. Plots consisted of three replications arranged in a RCB design. Each plot consisted of six rows with a row length of 3 metres and row spacing of 22 cm. The planting density of 250 seeds per square metre, resulted in approximately 3375 plants per variety, per year. Measured characteristics were based on 20 measurements per variety per year. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
