| 摘 要： | 研究采用父系半同胞相关法和单元内半同胞相关法分别估算了敖汉细毛羊的初生重、断乳重、断乳毛细度、周岁毛细度、周岁毛长、周岁剪毛量、周岁剪毛后体重、2周岁毛细度、2周岁毛长、2周岁剪毛量、2周岁剪毛后体重的遗传力。结果发现,这些性状的遗传力均为中高遗传力,在0.1～0.7之间。

| Abstract: | In this study,haif-sib correlation in sire,sib analysis within units were used to obtain esti-mates of Aohan Fine Wool Sheep's heritability including Birth Weight(BW),Weaning Litter Weight(WLW),Weaning Litter Staple Fineness(WLSF),One-age Staple Fineness(OASF),One-age Staple Length(OASL),One-age Wool Yield(OAWY),One-age Weight(OAW),Two-age Staple Fineness(TASF),Two-age Staple Length(TASL),Two-age Wool Yield(TAWY),Two-age Weight(TAW).The results showed all with middle to high heritability between 0.1to 0.7. |
