| 摘 要： | 采用巩乃斯种羊场中国美利奴羊（新疆型）肉用类型1995年4月—2001年4月周岁母羊生产性状的鉴定成绩和同年的剪毛测定结果。根据半同胞遗传协方差，对其部分生产性状的遗传规律做了分析。结果是剪毛后体重、剪毛量、毛长、目测羊毛细度遗传力分别为0．519、0．416、0．466、0．325。通过相关分析揭示了剪毛后体重、剪毛量、毛长、目测羊毛细度之间的表型相关与遗传相关。

| Abstract: | The data of four traits: body weight after wool cut,woolcut,wool length and wool fineness were collected on one year old Chinese meat-type Merino(Xinjiang) ewes in Gongnaisi breeding sheep farm from April 1995 to April 2001.Estimations of heritability from half-sib's genetic covariance analysis for body weight after wool cut,woolcut,wool length and wool fineness are 0.519,0.416,0.466 and 0.325 respectively.And the phenotypic correlations and genetic correlations between these four traits are evaluated by correlation analysis. |
