摘要： 为了更好的为鲿科鱼类良种繁育提供判别依据，通过测定杂交组合Ⅰ（江黄颡、黄颡及其正反交 F1代）、杂交组合Ⅱ（黄颡、江黄颡、粗唇鮠及黄颡♀×粗唇鮠♂F1代、江黄颡♀×粗唇鮠♂ F1代）的形态和框架数据，用聚类和判别2种方法进行分析。聚类结果显示：组合Ⅰ中，黄颡与江黄颡在杂交 F1中均表现出一定的母性效应；组合Ⅱ中，江黄颡♀×粗唇鮠♂比较倾向于其母本江黄颡，而黄颡♀×粗唇鮠♂比较倾向于父本粗唇鮠；判别结果显示：组合Ⅰ正反交中，其形态均匀的表现出黄颡和江黄颡的特征，没有较明显的表现出父本或母本的特征；组合Ⅱ中5群体的总的判别准确率为95.33%，清楚地显示出各群体之间的形态学差异。结论：（1）黄颡、江黄颡的正反交杂种和江黄颡♀×粗唇鮠♂杂种中均表现出明显的母性效应，而黄颡♀×粗唇鮠♂杂种则比较倾向于其父本粗唇鮠；（2）对比例性状参数和校正框架参数，综合使用比单独使用更能提高形态分类的判别能力，说明参数越详尽判别能力越强。

Abstract: In order to provide more discriminant basis for Bagridae fish breeding, through the form and framework data determination of Hybrid groupⅠ(Pelteobagrus vachelli, Pelteobagrus fulvidraco and their positive and negative hybrid F1 generation), and Hybrid groupⅡ(Pelteobagrus vachelli, Pelteobagrus fu lvidraco, Leiovassis crassilabrus, Pelteobagrus fulvidraco♀×Leiovassis crassilabrus♂ F1 generation, and Pelteobagrus vachelli♀×Leiovassis crassilabrus♂ F1 generation), two methods of clustering and discriminant were analyzed, clustering results showed that hybrid F1 generations showed some of the maternal effects in GroupⅠ; in GroupⅡ, Pelteobagrus fulvidraco♀×Leiovassis crassilabrus♂ F1 generation showed more similar to its mother and Pelteobagrus vachelli♀×Leiovassis crassilabrus♂ F1 generation tend to be more familiar to its father. Discriminant anlysise results showed: the GroupⅠpositive and negative hybrid F1 generations showed evenly to their father and mother features, no more apparently showed male or female characteristic; In GroupⅡ, 5 population discriminant accuracy rate was 95.33%, clearly showed the difference between each group morphology. The conclusion: (1) The positive and negative hybrid generations of Pelteobagrus vachelli and Pelteobagrus fulvidraco, Pelteobagrus vachelli♀×Leiovassis crassilabrus♂ F1 generation represent significant maternal effects; well Pelteobagrus vachelli♀×Leiovassis crassilabrus♂ F1 generation represent more paternal effects; (2) Comprehensive use of proportion of trait parameters and calibration framework parameters had more ability than used alone to improve discrimination ability of shape classification. The more detailed parameters, the stronger the discriminant ability.
