摘要
利用ABI3730测序仪对宁夏盐池地区196只滩羊的Myf-5基因进行了基因型判定,共检测到AA、AC、CC 3种基因型,频率分别为0.116 5、0.131 7、0.751 8;应用SAS软件对滩羊Myf-5基因与其4个生长性状之间的关系进行了关联分析。结果表明,AC基因型个体的3月龄体重、6月龄体重极显著高于AA、CC基因型个体(P<0.01);AC基因型个体的9月龄体重显著高于AA、CC基因型个体(P<0.05);不同基因型个体之间的初生体重无显著差异(P>0.05)。
The genotype of Myf-5 gene of 196 individuals of Tan Sheep in Yanchi region of Ningxia was determined by ABI3730 sequenator, and the association between different genotype of Myf-5 gene and four growth traits was statistically analyzed by using SAS software. Three genotypes of Myf-5 gene, including AA, AC and CC, were found. The three-month body weight and sixmonth body weight of the individuals of Tan Sheep with AC genotype were extremely significantly higher than those of the individuals of Tan Sheep with AA and CC genotype （P〈0.01）, and the nine-month body weight of the individuals of Tan Sheep with AC genotype were significantly higher than that of the individuals of Tan Sheep with AA and CC genotype （P〈0.05）.No significant differences in birth weight of Tan Sheep with different genotypes were observed （P〉0.05）.
