AAC Oriole is a semi-leafless red field pea (Pisum sativum L.) cultivar developed at the Lacombe Research and Development Centre, Agriculture and Agri-Food Canada, Lacombe, AB. It is shorter than most of the recently released yellow and green pea cultivars on the Canadian market with fair standability. It has early maturity, medium seed size, and round seed shape with a crude seed protein content of approximately 24%. AAC Oriole is resistant to powdery mildew caused by Erysiphe pisi DC. and moderately susceptible to mycosphaerella blight [caused by Mycosphaerella pinodes (Berk. & A. Blox.) Vestergr.] and fusarium wilt [caused by Fusarium oxysporum f. pisi (Linford) W.C. Snyder & H.N. Hansen]. It is adapted to all field pea growing regions in western Canada.
