  • In this paper the karyotype,C-banding and Ag-NORs of Semilabeo prochilus from Jin Sha River system (Yunnan Province) have been studied.The diploid number of Semilabeo prochilus is 50(16 m+20 sm+14 st)and NF=86.The centromeric distribution of heterchromatin has been demonstraed in most of chromosomes.The short arm of No.1 was found to be a complete heterochromatin.oreover,the interstitial heterochromatin has observed on the long arm Nos.9,10,11.Silver-staining showed 7 Ag-NORs at Nos.10,11,13 chromosomes,but only one Ag-NORs appeared in the No.13.Based on the above data,Semilabeo prochilus might be specilized species in genus Semilabeo.

Study on The Karyotype and Banding of Semilabeo prochilus (Pisces)

Abstract: In this paper the karyotype,C-banding and Ag-NORs of Semilabeo prochilus from Jin Sha River system (Yunnan Province) have been studied.The diploid number of Semilabeo prochilus is 50(16 m+20 sm+14 st)and NF=86.The centromeric distribution of heterchromatin has been demonstraed in most of chromosomes.The short arm of No.1 was found to be a complete heterochromatin.oreover,the interstitial heterochromatin has observed on the long arm Nos.9,10,11.Silver-staining showed 7 Ag-NORs at Nos.10,11,13 chromosomes,but only one Ag-NORs appeared in the No.13.Based on the above data,Semilabeo prochilus might be specilized species in genus Semilabeo.
