| Abstract: | The diploid number,2n of Paa boulengeri in Shuicheng of Guizhou is 26,including 5 pairs of macrochromosomes and 8 pairs of microchromosomes,in which,NOS.2,3,4,8,9 and 10 are submetacentric,the rest are metacentric.A secondary constrition has been observed in the short arm of a number of No.7,a Ag-NOR is located on the secondary constriction of No.7. |
