AAC Almonte is a tan-hulled, covered spring oat (Avena sativa L.) cultivar bred by the Ottawa Research and Development Center of Agriculture and Agri-Food in Ottawa, ON. It was supported for registration by the Ontario Cereal Crops Committee in January 2013 and registered in Canada on 20 Feb. 2014 (registration no. 7487). AAC Almonte is adapted to and has performed well in southern Ontario since its release due in part to its outstanding crown rust (Puccinia coronata Corda f. sp. avenae Eriks.) resistance.
