Origin & Breeding History: '6PSFG91B' (experimental designation 6035CW35-01) was developed using the pedigree method of plant breeding. The variety resulted from a cross between a proprietary variety and the variety ‘XW12Q' conducted at Pioneer Hi-Bred International, Inc. in Windfall, Indiana, USA in 2011. 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 6035CW35-01 in 2017. Breeder seed was established at the F8 generation in 2019.
Tests & Trials: The comparative trial for '6PSFG91B' was conducted at Pioneer Hi-Bred Production Limited in Caledon, Ontario during the 2022 growing season. 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. Measured characteristics were based on 24 measurements per variety. Results were supported by the official technical examination report 202200183, purchased from the Plant Variety Protection Office in Washington, District of Columbia, USA.
