PECULIARITIES OF GROUPING SOYBEAN BREEDING MATERIAL ACCORDING TO THE DATA OF STRUCTURAL ANALYSIS AND SEED QUALITY BY CLUSTERING METHOD

Martynov, M.A.
The article presents the results of the study of cluster analysis of promising soybean breeding material based on three-year data of structural analysis and seed quality. In each cluster, varieties and breeding lines were grouped according to quantitative traits of yield structure and their relationships. Based on the results of cluster analysis of soybean varieties and breeding lines, promising groups that are superior to others in certain characteristics were identified, which will allow for more targeted selection of breeding material. The peculiarity of varietal grouping by such traits as ripeness group, branching character and growth type was noted. In the cluster analysis for all the studied traits, the grouping of cultivars was made, first of all, according to the branching index. It was found that in the absence of traits directly demonstrating the nature of branching of the variety, the breakdown by this indicator was almost homogeneous
