Characteristics of a new spring barley variet Omsk 103

Abstract

The purpose of the research is to evaluate the new promising variety Omsky 103 in terms of yield and quality indicators in the conditions of Western Siberia. The studies were carried out in the period 2017-2021. 2019 was characterized by optimal conditions in terms of moisture supply (hydrothermal coefficient = 1.10); excessive moisture was noted in 2018; dry conditions – in 2017, 2020 and 2021 (hydrothermal coefficient=0.58…0.77). A new promising variety Omskiy 103 (variety medicum) of the mid-season group, drought-resistant, weak susceptibility to black, stone and dusty smut. The pedigree of the variety Omskiy 103 contains varieties and lines of breeding of the Omsk Agrarian Scientific Center (Pallidum 3733, Medicum 4602, Medicum 4771, Rikotense 3928, Rikotense 3928, Rikotense 4432, Omskiy 85, Omskiy 89), other scientific centers of the Russian Federation (Belgorodsky K-22089, Cyclone, Dobry, Olympus) and foreign selection (Keystone). A new promising variety Omsky 103 (variety medicum) of the mid-season group. The advantages of the new Omskiy 103 variety in terms of grain quality are an increased content of protein (13.27 %; + 0.15 % to st. and + 0.49 % to the Omskiy 102 variety) and starch (56.41 %; + 0.62 % to St. and +0.35 % to Omskiy 102). Also, a positive characteristic of the Omskiy 102 variety is an increased grain size (+10.04 g to st.). Due to the increased yield (5.36 t/ha; +0.77 t/ha to st. and +0.26 t/ha to the Omskiy 102 variety), the new promising variety forms an increased yield per unit area of protein (580.8 kg/a; +117 kg/ha to st. and +52.6 kg/ha to Omskiy 102) and starch (2.6 t/ha; +0.5 t/ha to st. and +0.2 t / ha to variety Omskiy 102). Variety Omsky 103 is recommended for use in agricultural production.
