摘要：

The present work provides new data on the banding pattern of diploid Cobitis taenia and its triploid hybrid females, which belong to the diploid–polyploid complex in the Vistula River tributary. C-banding, silver-staining (Ag), and fluorescent staining with chromomycin A3 techniques were used to describe the diploid and triploid karyotype. The karyotype of Cobitis taenia of 2n=48 was characterised by one pair of NOR-bearing subtelocentric chromosomes and at least four chromosomes with CMA3-positive sites. The C-positive heterochromatin was present in the centromeres of almost all chromosomes and the pericentromeric regions of several metacentric and submetacentric chromosomes.
