中文摘要：

利用998只中国美利奴羊（新疆型）周岁资料,应用通径分析方法研究了中国美利奴羊（新疆型）羊毛长度、剪毛后体重、毛弯曲分、毛油汗分和羊毛纤维直径对产毛量的影响程度,结果表明：这5个性状与产毛量的表型相关系数分别为0.5552、0.7048、-0.0759、-0.0917和-0.0105;对产毛量的直接通径系数分别为0.2103、0.6447、-0.0105、0.0324和0.1141。可见,剪毛后体重是影响中国美利奴羊（新疆型）产毛量的主要因素。

英文摘要：

The effect of staple length, live weight after shearing, wool bend score, wool oil score and fiber diameter on greasy weight was analyzed by path analysis using data on 998 Chinese Merino sheep （Xinjiang type） of 12 months of age. The results showed that phenotypic correlation coefficient between the five traits and greasy weight was 0. 5552, 0. 7048, -0. 0759, -0. 0917 and -0. 0105, and direct path coefficient of the five traits to greasy weight was 0. 2103, 0. 6447, -0. 0105, 0. 0324 and 0.1141, respectively. It was concluded that live weight after shearing was a main factor affecting greasy weight in Chinese Merino Sheep （Xinjiang type）.
