Abstract: To understand the genetic composition of Barbus capito and provide basic data in cytogenetics for appropriate utilization of its germplasm resources, karyotype of B. capito is studied. PHA and colchicine were injected into the head kidney and the chromosome samples were prepared by air-dried method. The results showed that there were 100 chromosomes in B. capito and its karyotype formula was 2n=16m+36sm+14st+34t, NF=152. It is considered that B. capito is likely to be tetraploid which has diploidization already, and originates from one of the primitive Barbinae fishes.
