本文应用通径分析方法对247只1岁母羊的资料整理分析,研究了体长、体重、污毛量等10余项数量性状间的相关关系,结果发现被毛密度、体侧部毛油汗浸润高度、剪毛前体重、体侧部毛长和腹部毛着生是影响产毛量的主要性状,并提出用这五个性状估测产毛量的预测方程和在若干经济性状选择中应注意的事项。

The phenotypic relations were studied by the path analysis method for over the 10 traits in Jiashike sheep. The data of 247 one old ewe were used. The computing results show that main traits to effect fleece weight have fleece density soaking oil-sweit height on body side wool, body weight before shearing, wool length on body side and wool growth on abdomen.
