摘要: 试验以肌细胞生成素(myogenin,MyoG)基因作为屠宰性状候选基因,以相同饲养条件下13周龄的贵妃鸡为研究对象,采用PCR扩增产物直接测序,检测该基因单核苷酸多态性(single nucleotide polymorphisms,SNPs),并进行MyoG基因SNP位点与屠宰性状的相关性分析。结果发现,在研究群体中检测到4个SNPs位点,存在T-T-A-G、T-T-A-A、C-C-A-G和C-C-G-A共4种单倍型,分别命名为H1、H2、H3和H4,经序列对比,可构建出H1H1、H1H2、H1H3、H1H4和H2H3共5种双倍型,对所定义的5种双倍型与贵妃鸡屠宰性状间进行关联分析,结果均未达到显著水平。

Abstract: In this study, myogenin (MyoG) gene as a candidate gene of slaughter traits, the genetic relationship between the single nucleotide polymorphism sites (SNPs) of MyoG gene and slaughter traits of 13 weeks old Royal chickens were analyzed. MyoG gene was amplified by PCR, the information of DNA sequences were obtained by direct sequenced of the PCR products. The results showed that four SNPs were found in the exons of MyoG gene. There were four haplotypes ((T-T-A-G (H1), T-T-A-A (H2), C-C-A-G (H3) and C-C-G-A (H4)) and five diplotypes(H1H1 ,H1H2,H1H3,H1H4,H2H3). By statistical analysis, it showed that there were no significant associations between diplotypes and slaughter traits of Royal chickens.
