Abstract
Leguminous crops are rich in protein, as a result of which they are an important component of crop biodiversity and food security. Providing the country's population with food is the main task of agricultural production. The purpose of this study was to study the genetic diversity of pea varieties and determine the degree of genetic discrepancy between the collection samples. 37 genotypes of the baleen pea morphotype, of various ecological and geographical origin, have been studied. The research was carried out in the fields of the breeding nursery of the Scientific and Production Center of Grain Farming named after A.I. Baraev. Cluster analysis is a procedure for grouping research objects by a specific data set. Observations were carried out on 12 quantitative signs, namely: the growing season from germination to flowering, day.; from germination to maturation, day.; yield, g/m2; number of internodes, pcs.; number of productive nodes, pcs.; plant height, cm.; height of attachment of the lower bean, cm.; number of beans per plant, pcs.; number of seeds in a bean, pcs.; number of seeds from a plant, pcs.; the mass of seeds from a plant, g.; the mass of 1000 seeds, g., using the analysis of the main components and cluster analysis to determine the relationship and genetic discrepancy between individuals. As a result of cluster analysis, 37 samples of pea germplasm were grouped into two main clusters and five subgroups, while the minimum number of samples was found in the second cluster, in group 3B (1 pc.), and the maximum number was found in group 1B (13 pcs.). The results obtained showed that among the two clusters, a separate genotype in group 2C has the highest average value for almost all the analyzed traits, except for the number of seeds in the bean.
