Results of research of soft winter wheat new lines of hexaploid level by morphological features, biological properties and biochemical parameters were given. During 2018–2020 in the Northern part of the Central Forest-Steppe of Ukraine the assessment of the general adaptive capacity by the yielding capacity and biological-agronomic traits are given and promising ones are highlighted (Donzorna, Flonormyra, Polezoriana). The new wheat lines have proved themselves well given the consistently high winter, drought resistance, and productivity, coefficient of variation is low, variance of stability, homeostaticity, and selection value – high. According to the biochemical composition of the grain, the studied lines are characterized by medium and high ‘raw’ protein content and gluten content. New selection wheat lines own by the technological indicators (the volumetric bread outut of 100 g of drough, the total baking rating), flour ‘quite satisfactory’, ‘good’, and ‘excellent’ score (Sviatdonivka, Flonormyra). The new wheat line Donzorna is characterized by the presence of 1BL/1RS wheat-rye translocation, which distinguishes it as a donor of resistance to biotic and abiotic factors and requires further more detailed study.
