| 摘 要： | 经对定边种羊场45只陕北细毛羊的11个数量性状与净毛量的相关分析、通径分析，证明净毛率和污毛量是直接影响净毛量的两个关键因素，周 岁体重、体长、胸围、体高等性状则是通过污毛量与净毛率的互作而间接影响净毛量的。因此提高陕北细毛羊净毛量，首先应对净毛率和污毛量进行选择提高，同时应兼顾周岁体重、体长、胸围和体高等性状。

| Abstract: | Shaanbei fine wool sheep were used to determine the correlation coefficient and path coefficient between the 11 quantitative characters and clean fleece weight. The results indicated that both the clean yield and greasy weight were the key factors influencing the clean fleece weight. The yearling weight, body length, heart girth and height acted on clean fleece weight indirectly by the interaction between greasy weight and clean yield. It was suggested that to increase the clean yield, the clean fleece rate and greasy weight be improved first, together with other factors such as yearling weight, heart girth and height. |
