The C-banding patterns of the 3 species in general were similar; differences were observed in chromosomes 4A and 6A. Besides 2 major 45S rDNA loci on chromosomes 1A and 5A, 2 minor polymorphic NORs were observed in the terminal part of 5AL and in the distal part of 6AS in all species. An additional minor locus was found in the distal part of 7AbL of T. boeoticum and T. monococcum, but not in T. urartu. Two 5S rDNA loci were observed in 1AS and 5AS.
