Abstract

Abstract: To understand the genetic composition of carp (Cyprinus carpio) in Dongping Lake and provide basic data in cytogenetics for exploration, protection and appropriate utilization of its germplasm resources, karyotype of carp (Cyprinus carpio) in Dongping Lake was studied. PHA and colchicines were injected into head-kidneys and then the chromosome samples were prepared by air-drying technique. The results showed that the chromosome number of Cyprinus carpio in Dongping Lake was 2n=100; the karyotype formula was 2n=20m 38sm 20st 22t. The total number of chromosome arms (NF) was 158. Compared with the karyotype of other fishes in Cyprinus, it was concluded that Cyprinus carpio in Dongping Lake was a more evolutionary group among fishes in Cyprinus.
