Origin & Breeding History: '3ABIA1619' was developed by Agrigenetics, Inc. using a pedigree method of plant breeding. In 2006, a cross was conducted between proprietary inbred lines in Arlington, Wisconsin, USA. Selected F1 ears were selfed with subsequent ear to row selections conducted from the F2 to F6 generations with final selections conducted in 2010. '3ABIA1619' was selected based on tassel size, pollen production, germination ability, stalk lodging resistance, late season plant health, yield in hybrid combination, grain quality, as well as disease and insect resistance. The F8 seed was bulked as breeder seed in Arlington, Washington, USA in 2011.

Tests & Trials: The comparative trial for '3ABIA1619' was conducted in Coteau-du-Lac, Quebec during the 2021 growing season. The trial was planted in a RCB design with 3 replicates. Each replicate consisted of one 3 metre long row with 76 cm between the rows. With approximately 20 plants per row, there was a total of 50 to 60 plants per variety. Measured characteristics were based on a minimum of 30 measurements per variety. Mean differences were significant at the 5% probability level based on paired Student's T-tests. Results were supported by the official technical examination report 202000304, purchased from the Plant Variety Protection Office in Washington, District of Columbia, USA.
