Pinnacle oat

Abstract

Pinnacle is a high-yielding, white-hulled oat (Avena sativa L.) cultivar postulated to carry the crown rust resistance combination Pc38, Pc39 and Pc68, which is highly effective against most of the present crown rust races on the Canadian prairies. It has very good resistance to loose and covered smut and good resistance to most of the prevalent races of stem rust, due to the likely presence of Pg2, Pg9 and Pg13 and moderate tolerance to barley yellow dwarf virus. Pinnacle has high test weight, high kernel weight, and very high percent plump kernels. According to its grain characteristics, including hull-to-groat ratio, protein content and oil content, Pinnacle should be acceptable for milling purposes. Pinnacle is well suited for the oat growing areas of western Canada and in particular the Black Soil Zone of Manitoba and Saskatchewan, where oat crown rust is prevalent.
