Abstract The aim of the research was to improve the technology of the breeding process for creating and selecting new highly productive samples of soft winter wheat using spelled in the breeding process. Research on the creation of a new variety was carried out in the conditions of the Uman National University of Horticulture. The starting material was the soft winter wheat varieties Glevakha and Krasnodarskaya 99, as well as a spelled wheat sample from the Foothill regions of the Carpathians. As a result of their hybridization, stabilization of offspring and individual selection, a sample 3872 was created, which was studied in a competitive variety trial during 2017–2019. During this period, the sample showed a high yield (7.0 t/ha) and an increased content of protein (15.0 %) and gluten (33.5 %). In 2019, he was transferred to a qualification examination under the name of Freya. The qualification examination was carried out in 19 branches of the Ukrainian Institute for the Examination of Plant Varieties during 2019–2021. During this period, the variety significantly exceeded the average yield in the Polissia zone and was characterized by an increased content of protein and gluten. According to the results of the qualification examination, the Freya variety is included in the State Register of Plant Varieties suitable for distribution in Ukraine in 2021. The recommended growing zone is Polissia. The Freya variety belongs to the mid-early group of plants. The type of development is winter. It stands out for its leveled stem and uniform ripening. The bush is semi-straight, vegetative organs of the plant with a weak waxy bloom. Stem is moderately performed. Colossus is pyramidal, loose, of medium length, spinous, white. The caryopsis is ovoid, large, red in color. It has a satisfactory level of winter and drought resistance, tolerant to diseases, resistant to shattering and germination of grain in the ear.
