Abstract

Goal. To study and select donors and genetic sources of basic economic traits for their further use in the selection process. Methods. Field — to establish the phenological phases of plant growth and development; measuring and weighing — to account for harvest; laboratory — to determine crop structure; mathematical and statistical — to analyze variance and statistical data processing to assess the reliability of research results. Results. The sample UKR006: 01021 Ideal was isolated from the studied soybean gene pool by ultra-early maturity. The duration of its growing season was 93 days. The maturation took place 6 days faster than in the standard variety UD0201975 Diona (97 days). The advantage of this sample is that it can be grown in basic and post-harvest and low-yield crops. “Large” — 19.8 cm (8 points) attachment of the lower bean above the soil surface was observed in the sample of soybeans UKR006: 01024 Oleshshia, “very large” — 21 cm (9 points) — in the sample UKR006: 01023 Pivdenna Krasunia. The number of productive nodes, the number of beans on the main stem and side branches, and the number of seeds per plant had the most significant-close connection with the mass of seeds from the plant. Conclusions. Sources were selected for the main economic features: samples UKR006: 01021 Ideal for ultra-early ripening, UKR006: 01024 Oleshshia, UKR006: 01023 Pivdenna Krasunia — for the height of the attachment of the lower bean. They may be recommended for use in the selection process.
