The purpose of the work: to study perspective lines in competitive variety testing and other nurseries, and to evaluate pre-selected breeding material. Research methods: field and laboratory, production testing, statistical analysis. Main results of the research:new early maturing and mid-maturing soybean varieties transferred to the SVV in 2017 are entered in the "State Register of Plant Varieties Suitable for Distribution in Ukraine" for 2020 and are recommended for cultivation in the Polesie and Forest-Steppe zones. According to the results of the state test on the seed yield, the early ripening variety Jacqueline (up to 3.11 t / ha) and the duration of the growing season (91-109 days), the mid-season variety Perepelochka, respectively, the yield up to 3.54 t / ha, and the duration of the growing season up to 116 days significantly exceeded the conventional standard in their group. By hybridization using the best varieties and breeding numbers, attracting fasciated plants with dense pubescence of the plant, as well as from multi-flowered forms, a new breeding material was created, which was studied in breeding nurseries of all levels. the best promising breeding numbers are 213-15, 289-15, and 427-15 with a seed yield from 2.34 to 3.04 t / ha. The best mid-season numbers (116-117 days 188-17 and 725-17 with a yield of 2.68-2.99 t / ha. Among mid-season numbers (118-131 days), numbers 110-18 and 680-18 stand out, the yield of which in respectively 3-13 and 2.97 t / ha.On average, over the years of testing 2016-2020, numbers 156-15 and 2.13-15 stood out among the ultra-ripening numbers with a yield of 2.67-2.71 t / ha, early ripening - 120-14 and 441-15 with a yield of 2.79 and 2.72 t / ha, as well as the best mid-season numbers 238-18, on average over four years of testing, the yield was 3.12 t / ha and 680-18 for three years of testing - 3.34 t / ha.
