T. miguschovae (GGAADD) was used as a “genetic bridge” to transfer valuable traits to the common wheat instead T. militina and Ae. tauschii. Lines with resistance to leaf rust, yellow rust and powdery mildew, as well as with high protein content (17–18 %) were selected. The lines with translocation Т2BL.2BS-2GL, 5BS.5BL-5GL, T6BS.6BL-6GL and substitution of chromosomes 1D(1Dt), 4D(4Dt), 5D(5Dt), 6D(6Dt) were identified. DNA analysis revealed that the lines can carry leaf rust resistance genes that are different from the known Lr39 and Lr50. Introgression lines have been successfully used in breeding. Five common winter wheat cultivars are developed.
