Medium and low level of agriculture in Siberia doesn’t allow realizing potential productivity of winter varieties of intensive type. It’s necessary to create multi biotype varieties of wheat adapted to local conditions. Selection material made according to international program with participation of Mexico, Kazakhstan and Russia gave possibility to form multi biotype selective samples in Siberia which possess standard variety ‘Omskaya 36’ in productivity and in other economical traits. The best samples are prepared to be given to state variety testing. Spring wheat selection is carried out according to 50 and more traits, the most important of them is tolerance to diseases, especially to stem smut, which shows a strong progress last years. It’s necessary to include absolutely new original material with valuable genes in selection and to develop multi biotype varieties on their basis, using different geographical regions with various climatic conditions. In this way we selected multi biotype selection numbers of spring wheat, which have an advantage over standard variety ‘Omskaya 36’ in competitive variety testing.
