Plant Sci. 91: 787-791. Summit is a white-hulled spring oat (Avena sativa L.) cultivar postulated to carry the crown rust resistance combination Pc38, Pc39, Pc48, and Pc68, which was effective against the prevalent pathotypes of crown rust on the Canadian prairies at the time of its release. It has very good resistance to loose and covered smut, moderately good resistance to most of the prairie stem rust races (likely due to the presence of Pg2 and Pg13) and is resistant to moderately resistant to barley yellow dwarf virus (BYDV). Summit has good kernel weight, percent plump kernels, and percent thin kernels. Summit exhibits high yielding capacity in the oat growing areas of western Canada. Summit was registered (Reg. No. 6529) in Canada 2008 November 29.
