Soybean variety Kyivskaya 91 is a promising genotypic material characterized by significant variability in the trait "number of pods on productive nodes of plants". Studies showed that maximum values of this indicator are achieved in early- and mid-maturing groups of varieties, indicating high yield potential. An important aspect of selection is the high coefficient of variation in hybrid generations F2–F4, especially in combinations with contrasting parental forms by height, such as Kyivskaya 91/Apollo. This indicates significant genotypic diversity and the possibility of effective selection to improve productivity. Additionally, the variety demonstrates certain resistance to adverse conditions, although in drought years it shows reduced performance, which is associated with limited realization of its genetic potential. The negative impact of diseases such as false powdery mildew affects the development of root tubers and, to a lesser extent, the above-ground growth of the plant, which is important to consider in agronomic management to maintain productivity. Kyivskaya 91 is recommended for cultivation in various agroecological zones where its use in grain production is possible. High initial growth energy, resistance to lodging and shattering ensure stable yields. The variety has potential for breeding work and further improvement of yield traits through effective selection for number of pods on productive nodes, making it a valuable component of hybrid programs.
