摘　　要：为探讨河南奶山羊体尺指标与体重的相关关系,更好地服务于选种、育种工作,本研究运用SPSS软件对119只河南奶山羊体尺、体重的测定结果进行了相关分析和通径分析,并建立了最优回归方程。结果表明:河南奶山羊的体重(Y)与体高(X1)、体长(X2)、胸围(X3)、胸宽(X4)、胸深(X5)、管围(X6)呈极显著正相关(P<0.01)。体高、体长、胸围、胸宽的直接作用和间接作用对体重的影响极大,得到最优回归方程为Y=0.317X1+0.326X2+0.181X3+0.121X4。In order to research the correlation between body size and body weight of Henan dairy goats for breeding selection,the data of 119 Henan dairy goats were analyzed by path analysis and correlation analysis with the SPSS software, then the most superior regression equations were established. The results showed that the body weight（Y） was significantly positively （P 〈0. 01 ） related to the body height（ X1 ）, body length （X2）, heart girth（X3） ,ehest width （X4） ,chest depth（X5） and Cannon circumference（X6）. The direct and indirect actions of the body height, body length, heart girth and chest width to body weight were extremely big. The most superior regression equation was Y =0. 317X1 ＋0. 326X2 ＋0. 181X3 ＋0. 121X4.
