KERNEL: soft red type, dark red

Origin & Breeding History: ‘6PWGL11B' (experimental designation 6035BR05-01) was developed using the pedigree method of plant breeding. The variety resulted from a three-way cross between a proprietary line and the varieties '25R30' and ‘25R25' conducted at Pioneer Hi-Bred International, Inc. in Windfall, Indiana, USA in 2013. The variety was advanced in Windfall, Indiana based on grain yield, test weight, maturity, disease resistance, plant type, plant height, head type, straw strength as well as milling and baking characteristics with one F6 line designated as 6035BR05-01 in 2018. Breeder seed was established at the F8 generation in 2020.

Tests & Trials: The comparative trials for ‘6PWGL11B' were conducted at Pioneer Hi-Bred Production Limited in Caledon, Ontario during the 2021 and 2022 growing seasons. There were 3 replicates arranged in an RCB design. Each plot consisted of 6 rows, each row measuring 3.2 metres long, with an inter-row spacing of 30 cm. The planting density resulted in 7800 plants per variety per year. Measured characteristics were based on 24 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
