New highquality spring oats variety Irtysh 33

Abstract

The variety is the primary means of production, providing consistently high yields with increased grain quality. Breeding work on oats in Siberia began in 1913. During 100 years of breeding work, more than 20 varieties of spring oats were created at the Omsk ARC. The research aims to characterize the new promising spring oat variety Irtysh 33. Research data from 2016–2022 are presented. Optimal conditions for moisture availability were observed in 2016 and 2019. (GTC 0.99 and 1.10); excessive moisture was noted in 2018; dry conditions – in 2017, 2020–2022. (GTC 0.58–0.77). A new promising variety of spring oats, Irtysh 33, is of the mid-season group and is resistant to lodging, drought, dust, and smut. Panicle semi-compressed, light yellow; panicle grain size 64 grains; grain of long-film type, white; spine is average; The awns are weakly expressed, slightly curved, and yellow. On average, during the research period, the new promising spring oat variety Irtysh 33 was characterized as high-yielding (+0.2 t/ha to the standard) with increased grain size (+3.7 g). Due to a significant increase in the standard for the leading indicators of grain quality (+0.7% in mass fraction of protein), (+0.9% in starch), (+0.5% in crude fat), there is an increased collection of nutrients from units of area about the standard: +0.05 t/ha of protein, +0.1 t/ha of starch and +0.02 t/ha of crude fat. The Irtysh 33 variety combines stability and plasticity in terms of protein mass fraction (bi>1 and <1) and refers to intensive (bi>1) in terms of protein and starch content of the grain. Stable (<1) protein content, crude fat, grain filminess, and yield. The variety has been included in the State Register of the Russian Federation since 2022 and is approved for use in the West Siberian (10) and East Siberian (11) regions.
