AC Lotta oat

Abstract

AC Lotta oat (Avena sativa L.) is a daylength-insensitive, spring-type, naked-seeded cultivar suitable for the feed, food (milling) and mixed-grain (oat and barley) industries in eastern Canada. It outyielded the naked seeded check cultivar Tibor by 10% in the Atlantic region, 19% in Quebec and 34% in Ontario in registration trials conducted in 1989 and 1990. It possesses genes conferring resistance to loose smut (Ustilago avenae (Pers.) Rostr.) and to race CR13 of crown rust (Puccinia coronata Cda. f.sp. avenae Eriks. and E. Henn.) and some races of stem rust (Puccinia graminis Pers. f.sp. avenae Eriks. and E. Henn.) in Ontario. It is susceptible to septoria blotch (Septoria avenae Frank f.sp. avenae) and barley yellow dwarf virus (BYDV).Key words: Avena sativa L., daylength insensitive, rust and smut resistance, cultivar description, naked oat
