Origin & Breeding History: '6PGEL62B' was developed using the pedigree method of plant breeding. The variety resulted from a three-way cross between two proprietary lines and the variety '25R56' conducted at Pioneer Hi-Bred International, Inc. in Windfall, Indiana, USA in 2007. 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 '6PGEL62B' in 2013. Breeder seed was established at the F11 generation in 2019.

Tests & Trials: The comparative trials for '6PGEL62B' were conducted at Pioneer Hi-Bred Production Limited in Caledon, Ontario during the 2019 and 2021 growing seasons. There were 3 replicates with plots arranged in a RCB design. Each plot consisted of 6 rows, each row measuring 6.0 metres long and 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.
