The whole broodstock of two Hungarian common carp farms—80 and 196 individuals—was analyzed by using random amplified polymorphic DNA (RAPD) assay and microsatellite analysis. Ten polymorphic RAPD markers and four microsatellites were selected to genotype both of the stocks. As expected, microsatellite analysis revealed more detailed information on genetic diversities than RAPD assay. Results obtained with both types of DNA markers showed lack of major differences between the genetic structure of the two stocks: heterozygosity values and allele frequencies were very similar. Dendrograms created from both sets of data did not show grouping of individuals according to stocks. Genotypes from the two stocks were also compared to those from a limited number of samples collected from other hatcheries and two rivers. Allele frequencies in the groups were similar, with the exception of wild carps. An interesting observation was that three private microsatellite alleles were found in the eight wild carp individuals, compared to the seven detected in the rest of the samples tested (372 individuals).
