摘　　要：利用SAS V6.12统计分析软件对185只滩羊与小尾寒羊杂交F1羔羊体重以及7个羊毛性状指标进行了表型相关和回归分析.结果表明:初生弯曲数与其他各项羊毛性状间均表现极显著的正相关(P<0.01),说明在选育中加强羔羊毛初生弯曲数的选择是一种有效地提高其他各项羊毛性状的途径.The phenotypic correlation and regression among eight traits of body weight and wool of 185 hybrid F1 lambs produced from Tan sheep crossing with Small-tailed Han sheep were analyzed by using the SAS V6.12 software. The results showed that the numbers of crimps of wool plaits at birth were positive correlated to other wool traits at extremely significant level（P〈0.01）. Thereby, it suggested that intensive selection of the numbers of crimps of wool plaits at birth could efficiently improve other wool traits.
