摘　　要：以京海黄鸡为试验材料,采用PCR-SSCP技术检测斑联蛋白(zyxin)基因外显子9的SNP,探讨zyxin基因该位点多态性与京海黄鸡屠宰性状之间的关系。结果发现该位点存在1个SNP突变位点,表现为3种基因型:AA、AB和BB。统计分析表明,公鸡的胸肌重AA基因型显著高于AB基因型(P<0.05),活体重和屠体重AA基因型显著高于BB基因型(P<0.05);母鸡的活体重、头重、爪重和屠体重AA基因型显著高于BB基因型(P<0.05),全净膛重AA基因型显著高于AB基因型(P<0.05)。Jinghai Yellow chickens were chosen for experimental animal,PCR-SSCP was used to detect the SNP of zyxin gene in exon 9.The correlation between this SNP genotypes of zyxin gene and slaughter performances was analyzed.The result showed that one mutation was found in exon 9 which comprised three genotypes,named AA,AB and BB.Statistics analysis showed that AA genotype was significantly better than AB genotype on pectoral muscle weight（P0.05）,and AA genotype was significantly better than BB genotype on living weight as well as carcass weight in cocks（P0.05）.AA genotype was significantly better than BB genotype on living weight,cerebaria,claw weight and carcass weight（P0.05）,and AA genotype was significantly better than AB genotype on eviscerated chicken weight in hens（P0.05）.
