Plain language summary

AAC Goldrush is a milling and baking quality hard red winter wheat that is well adapted to western Canadian growing conditions. Tested in official registration trials for four years, AAC Goldrush showed particularly good adaptation to Saskatchewan where it yielded 14% more grain than CDC Buteo, the predominant winter wheat variety in the province. AAC Goldrush reduces production risk for producers through its combination of excellent cold tolerance, good lodging resistance, medium-short height, and intermediate maturity. Production risk and sustainability are enhanced through resistance to stem and leaf rust and intermediate resistance to Fusarium head blight. It is anticipated that it will be commercially available in fall 2019.


AAC Goldrush is a hard red winter wheat (Triticum aestivum L.) cultivar eligible for grades of Canada Western Red Winter wheat. It was developed using a modified pedigree breeding method. AAC Goldrush was tested in replicated trials across western Canada for 6 yr: 2 yr for initial characterization followed by 4 yr of evaluation in registration trials. Based on 41 station–years of registration trial data, AAC Goldrush yielded significantly more grain than CDC Buteo and was similar to Flourish, Moats, and AAC Elevate. AAC Goldrush expressed very good winter survival, intermediate maturity, medium height straw with good lodging resistance, and average size kernels. Disease ratings at the time of registration were resistant to the prevalent races of leaf rust, moderately resistant to stem rust, intermediate in resistance to stripe rust and Fusarium head blight, and susceptible to common bunt. Leaf spot reactions were similar to the best check. The grain yield, agronomic characteristics, and disease resistance attributes of AAC Goldrush make it particularly well-suited to the eastern Prairie region of western Canada where CDC Buteo has been popular.
