Chaffy and hulless oat varieties react differently to the growing conditions in different cultivation zones. The varietal features of chaffy and hulless forms of oats were studied using a set of varieties harvested from 2012 through 2017 which were sown after fallows and cereal crops as forecrops in the southern forest-steppe of the Omsk Region. The frequency of formation of grain suitable for groats production for the varieties Orion and Sibirskiy golozerniy grown in different agro-climatic zones was determined. The data of grain groat quality evaluation of the collection of chaffy varieties sown in two zones: southern forest-steppe (Omsk) and northern forest- steppe (Tara) are discussed. It has been found that groat grain production is economically feasible when based on the varieties Orion and Pamyaty Bogachkova. At least equal yield of groats and protein per hectare after a cereal forecrop may be obtained by sowing the varieties Argument and Orfey. The sub-taiga zone is more preferable for groat grain production. At three-year average, the obtained grain exceeded the grain obtained in the southern forest-steppe zone in the following indices: thousand-kernel weight – by 3,6 g, grain-unit – by 32 g L, and groats yield – by 2,1%; though with lower protein content – by 1,15%. The hulless oat varieties were less yielding, but in terms of protein and groats yield per hectare they were at the same level with the chaffy varieties or had a slight advantage. The value of the hulless varieties consists in the lower energy consumption of the processing the grain into groats.
