We studied the collection of oat varieties in 2013–2015 in the conditions of the subtaiga zone of the Omsk region. The range was represented by genotypes of breeding of the Russian Federation (52.7 %), USA (16.2 %), Canada (7.2 %), Japan (5.4 %). The characteristics of the set are given according to the duration of the growth season, yield and elements of its structure, technological properties, and protein content. We determined the correlation between the indicators of grain quality and the parameters of the yield structure. We gave recommendations on the use of genetic sources to develop oat varieties with a high yield of grain and groats.
