| 摘 要： | 对长白母猪的7个体尺性状和5个繁殖性状进行了典型相关分析.结果表明,体尺性状与繁殖性状间的第1和第2典型相关系数均达极显著水平(P<0.01),其典型相关系数分别为0.913和0.881,占总相关信息的91.2%.分析还表明:母猪的体尺性状与繁殖性状存在相关关系;母猪的体重、腹围、乳头数和体高对产活仔数、初生个体重和断奶个体重起主要作用,对母猪的早期选择应侧重于这几个性状的表现.

| Abstract: | The analysis of canonical correlation for 7 body size traits and 5 reproductive properties of Landrace sows was conducted.The results showed that the first and second coefficients of canonical correlation for body size traits and reproductive properties were highly significant(P<0.01).The canonical correlation coefficients of the first and second were 0.913 and 0.881 respectively,which represented 91.2% for the total correlation.The results also showed that correlations were presented among body size traits... |
