| Abstract: |
| Three muhivariation analysis methods（principal component analysis，discriminant analysis and cluster
analysis）were used to investigate the morphological variations among two inbreds（NN and FF）and two corresponding
hybrids（NF and FN）in Penaeus monodon from two populations of African strain and“ Nanhai No.1” based on seven
morphological indexes. In the principal component analysis，three principal components were constructed，and the
cumulative contributory ratio was 68.35%. The discriminant analysis indicated that the discriminant accuracy of inbreds
populations was higher than that of hybrid populations. The cluster analysis revealed that two major groups were observed
for the four populations. The first group was NN，and the second group was FF，NF and FN. |
