Abstract: In the article the results of the trials in the North-Western part of the Kurgan region, where the most popular are the varieties: Omsk 36, Omsk 35, Chulaevsky, Raduga. Substantial areas are not zoned varieties: Iren, Omsk 38, Icarus, Aviad. In Northern areas early maturing varieties are the most reliable in the event of early autumn frosts and delaying ripening wheat in humid and cold weather end of the growing season. In this group of varieties the highest yield showed a new variety Kurgan selection Iset 45. Annual increase compared to Iren ranged from 4.0 to 6.4 t/ha, four years of 4.9 t/ha variety Maltsevskaya 110 has exceeded the Iren an average of 2.1 kg/ha. Consistently high productivity and responsiveness to the application of nitrogen fertilizers has shown Aria and Shurlock. In the late group these indicators are varieties of rainbow and Arch. In more favorable hydration 2011 higher yield potential in their groups of varieties: Iset 45 (24.0 kg/ha), Shurlock (26.7 kg/ha), Arch (28.5 kg/ha). In the Trans-Ural region receiving high-quality grain for years unstable and depends on the genotype of the variety and availability of heat during the formation and grain fills. In four years of high gluten content showed grade: Iren, Maltsevskaya 110, Aria Lutescens 70, on average 37–38 %. Some advantage in quality grains has more fast-ripening varieties.
