Selection for product quality is one of the most important tasks of creating new, more valuable, not only in quantity, but also in the quality of varieties produced. The article presents three-year data on the results of a study of biochemical parameters (protein, sugar, starch) and the yield of 57 pea samples taken from a competitive variety testing nursery. The studies were carried out in the departments of genetics and immunity and the selection of leguminous crops of the V.V. Dokuchaev Scientific Research Institute of Agriculture of the Central Black Earth Strip. The main goal of our work was to analyze, evaluate and select the best samples for the studied characteristics, which were distinguished in the period 2017-2019. In all test samples, the protein content in the grain was not lower than 20%. Samples with high protein content in the grain were revealed: 61/18 - 25.5%, 67/18 and 27/19 for 24.9%. The maximum protein yield per unit area was 6.5 centners / hectare for the 67/18 line and 6.7 centners / hectare for 58/18. Samples were characterized by high indices for the amount of sugar: 92/13 - 5.1% and 109/13 - 5.2%, which is 44% higher than the average values for all test samples and 37% higher than the best local sugar varieties of the standard Dudar. High starchy samples were found: 71/17 - 54.0%, 70/17 - 54.3%. These samples are of particular interest and will be used in further breeding work to improve quality indicators when creating new varieties of peas. A high degree of interdependence between the indicators ―yield‖ and ―protein collection‖ r = 0.944 ± 0.077 and a low degree of influence in the indicators ―mass of 1000 grains‖ and ―amount of protein in grain‖ r = -0.432 ± 0.212 were established.
