摘要
运用SPSS软件对67只小尾寒羊的被毛特征与繁殖率进行了相关分析,结果表明:小尾寒羊的被毛特征与繁殖率性状有极显著相关性(P<0.01);计算裘皮螺旋(X1)、裘皮波浪(X2)、细毛(X3)、粗毛(X4)遗传参数,得到最优回归方程为:y=0.71X1+0.53X2+0.47X3+0.349X4。
A research was made on 67 small-tailed sheep to study the relation between the characteristics of their clothing hair and the breeding rate by using the SPSS software.The result indicated that there was a distinct relativity between the characteristics of clothing hair and the breeding rate （ P〈0.01 ）. When we calculated the genetic parameters such as the fur spiral （ X1 ）, the fur wave （X2）, the soft fur （X3） and the shag （X4）, we got the optimum regression equation ：y=0.71X1＋0.53X2＋0.47X3＋0.349X4.
