摘　　要：通过对中卫山羊场10只种公羊的210只后代的三项不同性状与亲代相关系数的计算,各项性状互相之间相关系数的计算以及由种公羊后代各主要性状对其亲代进行的育种值估计,结果表明,初生重这一性状与亲代种公羊呈强正相关,初生毛长和初生毛股弯曲数这两个性状均与亲代种公羊呈弱正相关。在主要性状之间初生重与毛股长之间呈弱正相关,毛股长与弯曲数之间、弯曲数与初生重之间都呈强正相关。The correlation coefficient between three different characters of 210 offspring of 10 rams from Zhongwei goat farm and their parents and the correlation coefficient between various characters are calculated. The breeding values of major characters of rams＇ offspring on their parent are estimated. The results show that the trait of birth weight is positively correlated with parental rams and the two traits of birth hair length and primary feathers femoral bending number show a weak positive correlation with parental rams. Among the main traits a weak positive correlation is found between the birth weight and hair length and strong positive correlations are found between the hair length and the bending number as well as between the bending number and the birth weight.
