| Abstract: | The diploid individuals of Pinctada martensii aging 2 to 3 years old were wildness,and collected in Beihai,Guangxi.The triploid ones aging 1.5 years old were obtained by induction of 6-DMAP from the diploids.The karyotype is as follows:2N=28, the karyotype formula is 7M+3SM+3ST+1T,NF=48. 3N=42,the karyotype formula is 7M+3SM+3ST+1T,NF=72. The chromosome was classified on the criteria of Levan et al. |
