The six Abies species, A. laciocarpa, A. veitchii, A. sachalinensis, A. mariesii, A. faxoniana and A. georgei, were investigated for their chromosomes by the fluorescent banding method using fluorochromes chromomycin A₃ (CMA) and 4′,6-diamidino-2-phenylindole (DAPI). All six species have 2n=24 chromosomes and a similar karyotype consisting of seven pairs of long metacentric chromosomes and five pairs of shorter submeta- and subtelocentric chromosomes, supporting previous studies. Eight clear CMA-bands appeared at the interstitial region of one arm of long metacentric chromosomes in all species, and in A. veitchii and A. sachalinensis, their number varied from six to eight among plants and/or populations. A weak CMA-band appeared at the interstitial region of one chromosome pair, while a weak CMA-band appeared at the proximal region in some species. In most species DAPI did not produce clear bands, and sites of clear CMA-bands were DAPI negative. Only A. mariesii showed many DAPI-bands at the interstitial and/or centromeric regions of several chromosomes. A few weak DAPI-bands appeared in some other species. The fluorescent banding and FISH patterns reported in Abies species were compared and discussed with taxonomic treatment and molecular phylogeny of Abies.
