摘　　要：为更深入地探究杜泊羊体重与各项体尺指标之间的相关性,以便提升选育和选种工作,采用SPSS软件对新疆巴州地区种畜场294只周岁杜泊母羊的体尺、体重进行了相关分析,并建立了最优回归方程。结果表明,羊的体重(Y)与巴州地区杜泊羊体重与体高(X1)、体长(X2)、胸围(X3)、胸深(X4)、胸宽(X5)、管围(X6)、呈极显著正相关(P<0.01)。最终得到体尺与体重的回归方程为Y(体重)=4.308+0.213X2(体长)+0.142X3(胸围)+0.357X4(胸深)+0.463X5(胸宽)。最优回归方程为:Y=28.025+1.138X5(胸宽)。In order to further explore the correlation between the weight of Dupoe ewes and various body size indicators,better improve the selection work,SPSS software was used to apply 294 Dupoe ewes to the breeding grounds in Bazhou,Xinjiang.The ruler and weight were analyzed and the optimal regression equation was established.The results showed that the weight of the sheep(Y)and the weight and body height(X1),body length(X2),chest circumference(X3),chest depth(X4),chest width(X5),and tube circumference(X6)of Dupoe ewes in Bazhou Area,showed a significant positive correlation(P<0.01).The final regression equation for body size and body weight was Y(body weight)=4.308+0.213X2(body length)+0.142 X3(chest circumference)+0.357 X4(chest depth)+0.463 X 5(chest width).The optimal regression equation was obtained as Y=28.025+1.138X 5(chest width).
