AC Gwen hulless oat

Abstract

AC Gwen is a hulless 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 and Pg13, and moderate tolerance to barley yellow dwarf virus. AC Gwen has characteristics that confer good milling quality, such as high test weight, kernel weight, and percent plump kernels. The cultivar has suitable levels of protein and oil for food products or for animal feed. It has good resistance to lodging. AC Gwen is well suited for production in the oat growing areas of western Canada and in particular the Black Soil Zone of Manitoba and Saskatchewan where crown rust is prevalent.
