Abstract. Common spring wheat, traditionally sown across all soil-climatic zones in the Altai Krai, occupies more than 1.7 million hectares in total. About 30% of the cultivated area is concentrated in zones with a medium- and good moisture supply, where the biological potential of tall varieties limits the effectiveness of intensification agents (high doses of mineral fertilizers, foliage applications, growth stimulators and plant protection products). Recently, there has been an urgent need for dwarf varieties exhibiting high responsiveness to intensive agricultural backgrounds, which is solved by growing Western European varieties. This study aimed to develop fundamentally new dwarf varieties having a high yield potential and resistance to lodging and diseases, adapted to the soil and climatic conditions of Siberia. The study was conducted in the Altai Krai in 2008–2019 using conventional methods. The evaluation of breeding material was performed in field experiments, established after the fallow field. As a result, three promising high-intensity varieties with average grain yield of 4.19–5.66 t/ha and yield potential of more than 7 t/ha were developed based on source material from the German selection company Shtrube. The developed varieties exceed the current standards in productivity and crop index by 42–61% and 6.6–8.0%, respectively. In addition, the varieties are resistant to lodging and leaf diseases and form large grains with a gluten content of 28.2–30.2%. Since 2020, Lider 80 variety has been zoned in Western and Eastern Siberia. Gonets and Union varieties have been included in the State Testing Plan for the 10th, 11th and 12th regions.
