| 摘 要： | 为研究内蒙古绒山羊不同毛被类型遗传,收集内蒙古白绒山羊种羊场1990—2014年间54 044只绒山羊毛长(自然长度)的重复数据记录,按照不同羊毛长度将绒山羊分为三个类型:短毛型(≤13cm,SSL)、中间型(13cm羊毛长度≤22cm,ISL)和长毛型(22cm,LSL)。对毛长进行基本统计分析,发现内蒙古绒山羊个体之间的羊毛长度存在很大的差异,毛长度在5~34cm之间,而且毛长的分布规律基本符合正态分布。采用WOMBAT软件的AIREML算法进行方差组分分析和遗传参数估计。结果表明短毛型、中间型和长毛型的遗传力分别是0.11、0.16和0.22,长毛型的遗传力高于短毛型和中间型,并且短毛型和中间型属于低遗传力,而长毛型属于中等遗传力。从遗传进展上看,三种类型的遗传趋势相一致,总体上呈上升趋势,并且三种类型毛长的平均育种值每年分别增加0.005 9、0.011 3和0.014 1cm。研究表明长毛型的遗传进展比中间型和短毛型的遗传进展快,所以选择长毛型的绒山羊可以加速毛长遗传进展,为与其相关的重要经济性状间接选择奠定理论基础。
