为了研究大菱鲆的白化率、畸形率、存活率等3个性状与生长性状的关系，采用不平衡式巢式交配，通过人工授精技术，构建了66个全同胞家系。在初孵仔鱼第80天时，每个全同胞家系分别随机取样50尾个体，对其体长和体质量等生长数量性状进行测量和分析，并结合统计的白化率、畸形率和存活率进行各表型参数和性状间的相关分析，探讨了应用聚类分析方法确定生长性状选育指标的可行性。分析结果显示，大菱鲆生长性状选育和性能测定的适宜指标中，白化率与体长、体质量两两间均无显著相关（P＞0.05），畸形率与存活率呈极显著负相关（P＜0.01）。该聚类分析结果可以为大菱鲆速生苗种的选育提供参考依据。

Turbot was collected to initiate the genetic breeding program.Unbalanced nest design was adopted,and 6 6 full-sib families were obtained by vitro fertilization.Fifty individuals were randomly selected from each family,and the body length (cm)and body weight (g)of fry for 80 days were analyzed by correlation analysis and cluster analysis.Results showed that the albinism rate was not significantly correlated with body length and body weight (P>0.05).There was significant negative correlation between the abnormal rate and the survival rate (P<0.01).The results are helpful for the rapid breeding of turbot,Scophthalmus maximus L..
