Cytogenetic Analyses of Angelica Plants Using Fluorescence in Situ Hybridization

Karyotype analysis and chromosomal localization of 5S and 45S rDNAs using multi-color fluorescence in situ hybridization technique were carried out in two Angelic species. The numbers of diploid chromosomes were the same intwo species as 2n=22, however the lengths of chromosomes were varied from 4.25 to 6.50mm in A. gigas and 4.95 to 8.50 mm in acutiloba. The chromosomes of A.gigas were composed of five metacentric and six submetacentric pairs, while those of A.acutiloba were six metacentric , one submetacentric and four subtelocentric pairs.
