The purpose of the work: the selection of the best samples, the evaluation of breeding material for economically valuable characteristics; selection of perspective lines for the selection of breeding nurseries in the next year. Research methods: hybridization, selection of plants, field and laboratory experiments, production test, statistical analysis. The main results of the research: in the State register of plant varieties suitable for distribution in Ukraine, the ultra early ripe variety Arnika is entered. In the selection nursery, the selection of plants of all ripeness groups with the given performance parameters was carried out. Among the ultra early numbers of soybeans in the competitive variety testing, the number 849-12, 705-14 and №220-15 provided the greatest seed yield, which, according to the seed yield of 2.9 t / ha, exceeded the Legendа standard by 0.7 t / ha. In the previous strain test, the selection number 441-15 turned out to be the most high-performing one, with the duration of the 104-day vegetation period, the seed yield 3.0 t / ha exceeded the standard by 0.8 t / ha, and data indicators 215-15, respectively, were 99 days, 3.0 t / ha and 0.8 t / ha.In the competitive variety testing of early ripening varieties, the highest yield of seeds of 2.9 t / ha was obtained from breeding numbers 715-13, 186-15 and 604-14, which for the duration of the vegetation period, respectively, 110, 120 and 121 days exceeded the soybean standard Vilshanka 0, 8 t / ha. And, in the mid-ripening varieties, the most productive was No. 229-12, which, with a vegetation period of 126 days, the seed yield level of 3.1 t / ha exceeded the Kyivskay 98 standard by 0.5 t / ha. In the control nursery early maturing selection numbers were identified: 221-16, 272-16, 293-16 and others with the duration of the growing season of 99-110 days and the yield of seeds from 2.9 to 3.5 t / ha, as well as the mid-ripening - 311- 16 506-16, 292-16, 231-16, 618-16, 685-16, 9796-16, 9632-16 and others with the duration of the vegetation period from 112 to 125 days and the yield of seeds from 3.0 to 4, 3 t / ha.
