Alleles at the high-molecular-weight glutenin subunit loci Glu-U1 and Glu-Mb1 were analyzed in the tetraploid species Aegilops biuncialis (UUMbMb). The material for the investigation included the collection of 39 accessions of Ae. biuncialis from Ukraine (the Crimea), one Hellenic accession, one accession of unknown origin, F2 seeds from different crosses, as well as samples from natural populations from the Crimea. Ae. umbellulata and Ae. comosa accessions were used to allocate components of the HMW glutenin subunit patterns of Ae. biuncialis to U or Mb genomes. Eight alleles were identified at the Glu-U1 locus and ten alleles were revealed at the Glu-Mb1 locus. Among alleles at the Glu-Mb1 locus of Ae. biuncialis there were two alleles controlling the y-type subunit only and one allele encoding the x-subunit only.
