Barley varieties study on the grain quality in conditions of the Nakhichevan Autonomous Republic, Azerbaijan

During the period of 2017-18, we studied a collection of barley in the amount of 180 varieties of samples from 21 countries of the world, specially selected taking into account the problems of selection in conditions of rainfed agriculture. Evaluation of samples on the content of protein and lysine was carried out in the laboratory of Grain, Pulses and Industrial Crops of the Institute of Biological Resources of the Nakhichevan Branch of the National Academy of Sciences of Azerbaijan. To determine the protein in the barley grain, the SPEKTRAN-119 M. Infrared Analyzer was used, and the lysine content on the Hitachi Amino Acid Analyzer was used. Separate high-protein samples with increased (3.0%) lysine content in protein were isolated, which on both backgrounds are distinguished by a high content of protein in the grain and a relatively high concentration of lysine in the protein, which enhances their value as a starting material for quality selection.
