Аннотація: Two-tester analysis of topcrosses of soybean varieties differing in valuable economic traits and ecological and geographical origin was used in the study. The purpose of the research was to determine the combinational ability of soybean varieties by elements of the yield structure. The subject of research is a set of valuable economic traits of soybean varieties. Research methods was to evaluate both the ZCZ and SCZ effects of the five varieties under study: Sawyer 2-95, Ustia, Medea, Kyivska 97, and Kharkivska Skoroglaya in full two-tester topcrosses. In hybrid populations, the degree and frequency of positive transgressions have been determined, which is a breeding material for creating new varieties through hybridization. The high effects of ZKZ on plant height and attachment of lower beans in the variety Sawyer 2-95 and tester KiVin; on the number of productive nodes - in the varieties Sawyer 2-95, Medea, Kyivska 97 and tester KiVin; on the number of beans per plant - in the varieties Ustia, Kyivska 97 and tester KiVin; by the number of seeds per plant - in varieties Medea, Kyivska 97 and tester Goverla; by the weight of 1000 seeds - in varieties Sawyer 2-95, Kyivska 97 and tester Goverla; by the weight of grain per plant - in varieties Medea, Kyivska 97 and tester Goverla; by the yield - in varieties Medea, Kyivska 97 and tester Goverla. It was found that additive effects of genes were dominant in the genetic control of plant height and lower bean attachment, elements of yield structure and yield, but there was also a significant non-additive effect. In terms of the number of beans per plant, number of seeds per plant, and weight of seeds per plant, in the vast majority of hybrid populations, inheritance by the type of superdominance and dominance of the parental form with a higher manifestation of the trait was observed.
