Abstract: | Using five microsatellite loci, genotyping and genetic diversity estimates were obtained for nine samples representing seven
common carp breeds most widespread in Russia. For comparison, the samples of Amur wild common carp (Cyprinus carpio haematopterus) and a sample of European Hungarian carp were used. In the samples examined (n = 148) a total of 78 alleles were revealed. The highest mean allele number per locus (7.3) was identified in Amur wild common
carp, while the lowest number was found in Cherepets carps (4.0). In different breeds, the observed heterozygosities varied
from 0.819 (Altai carp) to 0.651 (Cherepets scaly carp). Three out of five microsatellite loci (MFW-24, MFW-28, and MFW-19) revealed a high level of population differentiation. In the dendrogram of genetic differences, all breeds clustered into
two groups. One of these groups was composed of the two strains of Ropsha carp, Stavropol carp, Amur wild common carp, and
the two samples of Cherepets carp. The second cluster included Altai carp (Priobskii and Chumysh populations), two Angelinskii
carp breeds (mirror and scaly), and Hungarian carp. The pairs of breeds/populations/strains, having common origin, were differentiated.
Specifically, these were two populations of Altai carp, two strains of Ropsha carp, as well as the breeds of Angelinskii and
Cherepets carps. The reasons for genetic differentiation of Russian common carp breeds, as well as the concordance of the
evolutionary histories of these breeds, some of which originated from the European breeds, while the others contain substantial
admixture of the Amur wild common carp, are discussed. |
