摘要：

为了对金定鸭体型性状的选育提供方向和重点。通过测定金定鸭的10个体型性状，计算各性状的平均数与变异性指标和性状间的相关系数。结果表明：种公鸭的10个体型性状可简化为3个主成分（占信息总量的85.441%），可从这3个主成分中选取体重、胸深、骨盆宽、胫围和颈长为代表性的性状指标。蛋母鸭的10个体型性状可简化为4个主成分（占信息总量的85.244%），可从这4个主成分中选取体重、骨盆宽、胸宽、胸深、胫长和颈长为代表性的性状指标。对金定鸭体型性状进行主成分分析，有利于明确金定鸭的体型特征，所研究的结果为金定鸭的选育研究提供参考依据。

Abstract:

Ten body type traits of Jin-Ding Duck were studied. The Mean and variability of indicators of these traits and the coefficients of correlation among them were computed, the indexes which provided the scientific basis for breeding and improved the native breeds. The result indicated that ten body type traits were divided into three components (85.441% cumulative for the male, and the representative traits were weight, Chest depth, pelvis width, Tibia Wai and Neck length. Eleven body type traits were divided into four components (85.244% cumulative) for the female, and the representative traits were weight, pelvis width, chest width, Chest depth, Sunenaga and Neck length.
