摘要
[目的]揭示荆江鸭的生长与产蛋及蛋品质性状之间的典型相关性,为提高蛋鸭的生产水平和加快选育工作提供参考依据。[方法]采用典型相关分析方法,对荆江鸭的生长性状与产蛋及蛋品质性状等性状间的17个变量的相关性进行了分析。[结果]生长性状与产蛋和蛋品质性状的第1个典型相关系数达到显著水平(P<0.05),典型相关系数为0.461,其相关信息(贡献率)占2组性状间总相关信息的27.2%,在2组性状中起主要作用的性状包括开产体重、初生重、蛋黄重和蛋黄比率。[结论]该研究结果对于利用生长性状对荆江鸭进行早期选育具有一定的指导意义。
[Objective] The aim was to analyze the canonical correlation between the growth traits and laying traits,egg quality traits of Jingjiang duck and provide reference basis for improving the production level of laying ducks and speeding up the breeding.[Method] Using canonical correlation method,the correlation between 17 variants（the growth traits and laying traits,egg quality traits） of Jingjiang duck were analyzed.[Result] The first coefficient of canonical correlation for the growth traits and laying traits,egg quality traits was significant（P 0.05）.The canonical correlation of the first coefficient was 0.461,which represented 27.2% for the total correlation.The main traits for canonical correlation coefficients were the puberty weight,the birth weight,yolk weight and yolk ratio.[Conclusion] The research results had certain guiding significance for the early breeding of Jingjiang duck using the growth traits.
