利用微卫星技术对凉山半细毛羊核心育种群206个个体第1、2、3、9号染色体上的18个微卫星位点进行研究, 检测其基因型, 利用SAS 程序下的GLM对18个微卫星位点与羊毛性状的关系进行方差分析和多重比较, 结果发现7个微卫星位点对部分羊毛性状存在显著或极显著影响, 同时, 在这些位点上找到对羊毛性状有利的基因型。

Eighteen microsatellites on chromosomes 1, 2, 3, 9 were studied to detect their genotypes in 206 individuals in a Liangshan Semi-fine Wool Sheep nucleus breeding population. A GLM procedure was used to analyze the effects of these 18 microsatellites on wool traits. Results uncovered 7 loci that had a significant impact on wool traits. Genotypes of that favorably affect wool traits were determined.
