Stainless is a grey-hulled spring oat ( Avena sativa L.) cultivar postulated to carry the crown rust resistance gene, Pc91, which was effective against the prevalent pathotypes of crown rust races on the Canadian prairies at the time of its release. Stainless could possibly also carry one or more of the crown rust resistance genes, Pc38, Pc39, and Pc68. It had very good resistance to loose and covered smut, good resistance to the prairie stem rust races (likely due to the presence of Pg2, Pg13, and Pga) and moderate tolerance to barley yellow dwarf virus (BYDV). Stainless had high kernel weight, intermediate percent plump kernels, intermediate percent thin kernels, and high levels of total dietary fibre. Stainless exhibited high yielding capacity in the eastern portion of the Black soil zone of western Canada where resistance to rust diseases is important. Stainless was supported for registration by the Prairie Grain Development Committee in February 2007. Stainless was registered (Reg. No. 6422) on 2008 Apr. 07.
