The article presents the list of varieties included in the study of new early-ripe Ukrainian soybean varieties in the conditions of the Western Forest-Steppe zone. The research was laid down during 2017-2019 years on the experimental field of the Department of Technologies in Plant Growing at Lviv NAU in order to study the new early-ripe Ukrainian soybean varieties. The soybean varieties, used in the studies, included: Ustia, Muza, Arnica, Khvylia, Vilshanka, Siverka, Suziria (originator – NSC “Institute of Agriculture of the NAASU”). All varieties are early maturing. The vegetation period varies from 83 to 107 days. The varieties are characterized by resistance to the most common diseases, cracking of beans and grain loss. They can be used as a precursor for winter crops. The early-ripe varieties are suitable as crops stubble. The Ustia variety has been in the State Register since 2002. The weight of 1000 seeds is equal to 160 g. Seeds contain 41-42% protein and 19-20 % fat. The Muza variety has been in the State register since 2015. It is derived by the method of multiple individual selection from hybrid generations Yug-30 / Ustia. The weight of 1000 seeds is equal to 235-245 g. The seeds contain 41-42 % protein and 20-21 % fat. The Arnika variety is entered in the State register in 2016. It is derived by the method of individual selection from the combination of crossbreeding of two early-ripe and productive lines of 242 and 427. The weight of 1000 seeds is equal to 155-160 g. The seed contains 40-42 % protein and 20-21 % fat. The Khvylia variety has been in the State Register since 2013. It is derived by the individual selection from the hybrid population L.364 / Cherniatka. The weight of 1000 seeds is equal to 158-162 g. The seeds contain 40-42 % protein and 21-22 % fat. The Vilshanka variety has been in the State Register since 2011. It is derived by the method of multiple individual selection from the hybrid L.955 / Cherniatka. The weight of 1000 seeds is equal to 240-250 g. The seeds contain 41-42 % protein and 21-22 % fat. The Siverka variety has been in the State Register since 2013. It is derived by individual selection from the hybrid population of Yug-30 / Ustia. The weight of 1000 seeds is equal to 170-175 g. Seeds contain 41-42 % protein and 20-21 % fat. The Vyshyvanka variety has been in the State Register since 2019. The weight of 1000 seeds is equal to 144-183 g. Seeds contain 38-39 % protein and 22-23 % fat. The Suziria variety has been in the State Register since 2011. The weight of 1000 seeds is equal to 220-240 g. Seeds contain 42-43 % protein and 20-21 % fat.
