The Northern Trans-Urals is a region of intensive agriculture that needs high-yielding varieties that are resistant to lodging and a-biotic environmental factors, forming high-quality grain. In this respect, as a starting material for breeding, Canadian varieties with good technological indicators of grain and Norwegian varieties with high resistance to lodging and well-expressed economic and valuable characteristics are of interest. An important indicator when creating wheat varieties is the resistance to pre-harvest germination of grain on the root. The conjugacy of this feature with the yield is high and is expressed negatively - r = -0.922. Among the studied cultivars, Demonstrant (Norway) and 5603HR (Canada) stand out for their resistance to grain germination in the ear. Norwegian varieties are characterized by multi-grain ear, fine grain and compacted ear. Marker traits of drought resistance – the length of the upper internode and the removal of the ear, are better expressed in the standard of Omskaya 36, varieties of local selection and varietals - Laban and GN 06600 (Norway). In arid conditions, these varieties have a more pronounced yield. The best in this respect is Kazakhstan one - Astana (2.27 t/ha). The intensity was highlighted by the variety - GN 06600 (Norway) - 5.05 t/ha. The revealed conjugate relationships in the studied traits allow to purposefully conduct breeding work.
