摘　　要：采用SAS统计分析系统对绿北绿荆杂交鸭的5个体尺性状和8个屠体性状进行了典型相关分析。结果表明,体尺与屠体性状的第一典型相关系数达到了显著水平(P<0.05),占总相关的87.82%。体尺与屠体性状间的相关主要是由于胸围与腿肌重、胸肌重的相关引起的。在达到显著水平的一对典型变量中,体尺性状的典型变量对屠体重的预测能力较强,屠体性状的典型变量对胸围的预测能力较强。在实际选育过程中,选择体尺性状可达到提高屠体性状的目的。Canonical correlation analysis was carried on 5 body size traits and 8 slaughtering traits of Lvbeilvjing hybrid ducks by using SAS. The results showed that the first canonical correlation coefficient between body size and slaughtering traits were significant （P〈0.05）, which represented 87.87% for the total correlation. The correlation between body size and slaughtering traits was mostly caused by the correlation between chest circumference and weight of leg muscle. Canonical variables of body size traits could predict slaughtering body weight, and canonical variables of slaughtering traits could predict chest circumference effectively. It indicated that slaughtering traits could be increased when selecting on body size in practice.
