Aim. The aim of the study was to develop and study T. aestivum material with introgressions from Ae. biuncialis. Methods. Quantitative traits of F4 lines from crossing wheat with Crimean accessions of Ae. biuncialis were studied. SDS and APAG electrophoreses of storage proteins were used to identify alleles at the Glu-1 and Gli-1 loci, including introgressed ones. Results. F4 lines from crosses of wheat with Ae. biuncialis showed a wide range of yield traits. Some lines had a clavate spike and a hairy leaf blade. Using storage proteins as genetic markers the presence of chromosome 1U was identified among the progeny of plants analyzed; some of them had translocation of arm 1UL. Lines with introgressions of chromosome 1M were not revealed. Conclusions. T. aestivum lines with introgressions from Ae. biuncialis were developed without amphidiploid production. Lines with chromosome 1U were selected, including lines with translocations of arm 1UL.
