Abstract

The results of the study of grain and fodder oat varieties in the competitive variety trial of the Omsk Agrarian Research Center are dis-cussed. The article provides data on the green food yield and its protein yield for the period from 2018 to 2020. The samples were tested under conditions with contrasting moisture content. Physiological indices of vari-eties are also analyzed: leaf area, accumulation and distribution of dry bi-omass as well as percentage of protein. The response of oat varieties by year to different weather conditions is shown. A favorable year has been identified for the formation of a common assimilating area of oat plants. It was revealed that the protein content in the vegetative mass of oats varies oppositely with the total yield. The accumulation of dry biomass in onto-genesis characterizes the photosynthetic activity of plants. It is in a positive relationship with their yieldability. The selection of grain and fodder oat varieties begins with the SP-2 nursery.

Highlights

From more than 14 billion only 10% of the world's agricultural land has favorable conditions for plant cultivation
Our studies have shown that the conditions of the growing season of 2019 had a positive impact on the formation of dry biomass of oat plants
On the basis of the obtained experimental data, we have identified the main characteristics of the model of varieties of paleaceous and naked oats of medium-ripened and mediumlate type for the natural and climatic zones of Western Siberia to the green food

Summary

Introduction

From more than 14 billion only 10% of the world's agricultural land has favorable conditions for plant cultivation. The Omsk Agrarian Research Center (until 2017 – Siberian Research Institute of Agriculture) has been involved in the selection of oats since the 1960s in three main areas of use: feeder grain, food grain, and fodder grain. To ensure the success of the selection program, it is essential to use a well-studied source material containing signs marking yield and protein content as significant components of feed productivity.
