| 摘 要： | 本文应用通径分析方法,研究了中国美利奴羊羊毛密度、伸直长度、纤维直径和剪毛后体重对净毛产量的影响程度。结果表明,这四个性状对净毛产量的直接通径分别为0.7747,0.7337,0.1832和0.4061;间接通径分别为-0.4267,-0.2512,0.0509和-0.2541;决定系数分别为0.6001,0.5383,0.0336和0.1649。羊毛密度是影响中国美利奴羊净毛产量的主要因素。

| Abstract: | The effect of wool density, strentched length, fiber diameter and liveweight on clean wool weight in the Chinese Merino was studied by path analysis. The results showed that the direct path coefficients of the traits to clean wool weight were 0. 7747, 0. 7337, 0. 1832, and 0. 4061 , the indirect path coefficients -0. 4267, -. 2513, 0. 0509, and -0. 2541 , determination coefficients 0. 6001 , 0. 5383, 0. 0336 and 0. 1649, respectively. It was concluded that wool density was main factor affacting clean wool weight in the Chinese Merino. |
