Ecological variability of the quality of oats varieties depending on vegetation conditions

Abstract

Abstract Studies were conducted on the environmental variability of the quality of oat varieties depending on the growing conditions in the Khabarovsk territory (Russia). In recent years, the demand for high-quality oat grain has increased. The conditions for cultivating grain crops in the same soil and climate zone are very diverse. The research was aimed at studying the influence of the environment during the growing season on the quality of oats. It was noted that the most affected indicators were grain filminess (coefficient of variation (CV) is 16.8%) and the content of lysine in the grain (CV is 18.8%). To an average extent, the conditions of the year affect the characteristics of the protein content in the grain (CV is 10.1%) and the nature of the grain (CV is 14.5%), which is determined by the ecological fitness of oat varieties when cultivated in the region. The low variability of the 1000 grain weight trait (CV is 9.4%) indicates a weak response of oat genotypes to changes in environmental conditions. Based on a set of quality indicators, the varieties of oats Marshal, Cardinal and Peredovik. The Marshall oats variety was characterized by a high and stable protein and lysine content. In the variety Peredovik, a high mass of 1000 grains and a full grain weight were noted. Over the years of research, the Cardinal oat variety had a low pitting and a large mass of 1000 grains. We recommend them for sustainable crops of high-quality grain for various food uses. These varieties of oats are recommended for cultivation in the Khabarovsk Territory.
