An asymmetric potato hybrid and its parental lines were cytogenetically examined. DAPI (4?-6-diamidino-2-phenylindole) staining was used to count chromosomes in all analysed lines and revealed the presence of minichromosomes in the hybrid genome. Fluorescent in situ hybridization (FISH) with rDNA sequence as a probe helped to determine the ploidy level of analysed lines and revealed that none of the minichromosomes contains rDNA repeats. CMA (chromomycin A3) band occurred to be a new chromosome marker that identifies potato chromosome No.1. It was possible to detect a deletion in one of four chromosomes No. 1 of the asymmetric potato hybrid. On the basis of these analyses a karyotype of the asymmetric hybrid was constructed.
