| 中文摘要: |
| 以斑节对虾南海1 号（N）和非洲品系（F）作为亲本，进行自交与杂交，获得4 个子代群体
NN（N♀×N♂）、NF（N♀×F♂）、FN（F♀×N♂）和FF（F♀×F♂）。运用多元分析方法，采用7 个测量
性状对其形态进行比较研究。主成分分析结果显示，共构建了3 个主成分，累计贡献率为68.35%；判别分
析结果显示，自交群体的准确判别率相对较高，杂交群体的正确判别率较低；聚类分析结果显示，NN 独立
聚为一支，FF 与NF 聚为一小支后与FN 聚为一支。 |
| 英文摘要: |
| 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. |
