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. C omprehensive karyotypic analysis confirmed Triticum umbellulatum as th e 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 la rge modifications when compared with the ancestral U and S-1 genomes.
