摘要Campanumoea is a small genus in the family Campanulaceae, with species divided into sections Campanumoea and Cyclocodon. Sixteen accessions from Campanumoea and related genera native to China were used to study their karyotype. The results showed that chromosome characteristics were different between the two sections. For Campanumoea, the karyotypic formula was 2n = 2X = 2m + 12sm + 2st = 16,3A and for Cyclocodon it was 2n = 2X = 6m + 12sm = 18,3B. These data, combined with chromosomal length characteristics, support the restoration of section Cyclocodon as a genus. However, the incorporation of section Campanumoea into Codonopsis requires more evidence. Comparison of chromosomal length and haploid set length revealed that chromosomal segment rearrangements occurred within sections of Campanumoea and between genera, with the difference within sections being greater than that between genera. Therefore, chromosomal segment rearrangements are present in Campanulaceae, implying that chromosomal segment rearrangement plays an important role in the evolution of diversity in Campanulaceae. By comparing the chromosomal characteristic in section Campanumoea and the genus Adenophora, we concluded that the secondary chromosome type such as n = 17, 18 would be derived by autopolyploidization of n = 9, and by chromosome fusion.
