Cytogenetic identification of Triticum peregrinum chromosomes added to common wheat

C-banded karyotypes of a complete set of 14 Triticum peregrinum whole chromosome addition lines and 25 telosomic addition lines are reported. The added T. peregrinum chromosomes were not structurally rearranged compared with the corresponding chromosomes of the donor accession. Comprehensive karyotypic analysis confirmed Triticum umbellulatum as the donor species of the U-v genome and identified Triticum longissimum as the donor species of the S-v genome of T. peregrinum. Neither the U-v nor S-v genome chromosomes of the T. peregrinum accession showed large modifications when compared with the ancestral U and S-1 genomes.
