Abstract: The distribution of heterochromatin on the chromosomes of V. cracca L. subsp. cracca (2n = 14) and V. bithynica L. (2n = 14) was established with the aid of the C-banding technique. The chromosomes of both species have centromeric C-bands. When compared, prominent bands at the ends of the short arms on 4 chromosomes of V. cracca subsp. cracca were observed, while in V. bithynica only 1 chromosome had a prominent band at the end of the long arm. The C-banding patterns in the 2 species were different, and it was determined that heterochromatic regions were more dense on the chromosomes of V. cracca subsp. cracca. The present results are compared with previously published data on Vicia species.
