Origin & Breeding History: '16162679' (experimental designation YW16J) originated from a three way controlled cross between proprietary selections from Pioneer Hi-Bred International Inc. Using a pedigree method of plant breeding, the final cross was conducted in 2008 in Windfall, Indiana, USA. The F1 was transplanted in a field nursery in Windfall, Indiana. From 2010 to 2015, selections were made at each filial generation based on disease resistance, plant type, plant height, head type, straw strength, maturity, grain yield, test weight along with milling and baking characteristics. In 2016, the F9 was further assessed in elite yield testing and was headrow purified and bulk increased.

Tests & Trials: The comparative trial for '16162679' was conducted during the 2018 growing season at Pioneer Hi-Bred Production Company in Caledon, Ontario. There were 3 replications arranged in an RCB design. Each plot consisted of 6 rows, with a row length of 6 metres and row spacing of 30 cm. Each plot had approximately 2600 plants. Measured characteristics were based on 24 measurements per variety per year. Mean differences were significant at the 5% probability level based on a Student`s t-test. Results were supported by the official technical examination report number 201800081, purchased from the Plant Variety Protection Office, Washington, District of Columbia, USA.
