摘　　要：对杂种猪的生长速度、胴体品质和肉质3组性状的21个变量进行了典型相关分析。结果表明:生长速度和胴体品质性状间以及胴体品质和肉质性状间的第一、二个典型相关系数达极显著水平,分别占总相关的100%和65.38%;生长速度和肉质性状间第一个典型相关系数达显著水平,占总相关的69.12%。其典型相关系数依次为:0.8890、0.6190;0.8219、0.7049和0.5183。Canonical correlation of 21 variables in 3 group-traits (growth rate,carcass quality and meat quality ) for crossbreeding pigs were studied. The results showed that the first, the second coefficient of canonical correlation between the growth rate and the carcass quality, as well as the carcass quality and the meat quality, was highly significant. The canonical correlation coefficients were 0.8890, 0.6190 and 0.8219, 0.7049 , they represented 100% and 65.38% respectively for the total correlation between 2 groups. The first coefficient of canonical correlation between the growth rate and the meat quality was 0.5183. It was significant and expressed 69.12% for the total correlation.
