A new high-quality variety of spring barley Omsky

Abstract

Within the framework of the grant “Creation of selection and seed production and breeding centers in agriculture to create and implement in the agricultural sector of modern technologies based on own developments of scientific and educational organizations” in 2021, the variety of spring barley Omsky 103 was transferred for state variety testing. The research aims to characterize the productivity and grain quality of the new promising Omsky 103. The study was conducted from 2017 to 2021. Optimal moisture conditions were represented in 2019 (GTC = 1.10), excessive moisture was observed in 2018, and dry conditions in 2017, 2020, and 2021 (GTC = 0.58-0.77). The new promising variety Omsky 103 (variety medium) belongs to the intermediate array, is a droughtproof variety, and has low susceptibility to black, stone, and dust smut. In the breeding record of sort Omsky 103, there are varieties and lines of breeding of Omsk Agrarian Research Center (Pallidum 3733, Medicum 4602, Medicum 4771, Ricotense 3928, Ricotense 3928, Ricotense 4432, Omsky 85, Omsky 89), other scientific centers of Russia (Belgorod K-22089, Cyclone, Kind, Olimp) and foreign breeding (Keystone). The advantages of the new variety Omsky 103 in terms of grain quality are higher protein content (13,27%; +0,15% towards the standard and +0,49% towards the type Omsky 102) and starch (56,41%; +0,62% towards the bar and +0,35% towards the variety Omsky 102). A positive characteristic of the array Omsky 102 is also an increased grain size (+10.04 g against the standard). Due to the increased yield (5.36 t/ha; +0.77 t/ha against the norm and +0.26 t/ha against the variety Omsky 102), the new perspective variety forms an increased grain harvest per unit area of protein (580.8 kg/a; +12.0% vs. standard and 22.5% to the Omsky 102) and starch (2.6 t/ha; +13.0% vs. standard and 21.7% to the variety Omsky 102).
