Abstract

The article presents the results of a study of two varieties (Povolzhskaya 86, Povolzhskayaniva) and two promising lines (Erythrospermum 3730, Lutescens 4043) for the content of essential amino acids: lysine, methionine, tryptophan, threonine, isoleucine, valine, leucine, histidine, phenylalanine. The studies were conducted in 2018-2019. The objectives of the study included: assessment of the influence of weather conditions and the genetic potential of varieties and lines on the content of essential amino acids; determination of the amount of essential amino acids in new varieties and promising lines. The amount of essential acids in winter wheat grain is primarily affected by the weather conditions of the growing season and the genetic characteristics of the variety. The content of lysine, tryptophan, valine, leucine, histidine, and phenylalanine was the highest in 2018, characterized by increased precipitation and high temperatures in April, May, and July. The content of trionine, methionine was maximum in 2019 with increased precipitation and reduced temperature. The new variety Povolzhskayaniva had high levels of amino acids leucine, histidine, valine. The promising Erythrospermum 3730 line had the highest content of the amino acids tryptophan and isoleucine. The promising Lutescens 4043 line showed a high content of tryptophan and isoleucine amino acids.
