摘　　要：本研究以IGF1R基因作为影响苏禽黄鸡生长性状的候选基因,基因第16外显子单核苷酸多态性采用DNA测序和PCR-SSCP技术进行分析,并与鸡的生产性能进行关联分析。结果表明,共发现2个SNPs位点(C143082G和A143135G),在初生重方面,CC基因型个体的体重显著高于AA、AB、AC、BB和BC基因型个体的体重(P<0.05)。推测IGF1R基因可能是影响鸡体重的主(效)基因或与影响体重主(效)基因紧密连锁。In this study ,IGFIR gene as candidate gene of Suqin yellow chicken growth traits, using DNA sequencing and PCR-SSCP technology to analyze the correlation between IGFIR gene 16 exon SNPs and chicken production performance.The results showed that 2 SNPs loci （C 143082G and A 143135G ）were found, the birth weight of CC genotype individuals were significantly higher than those in AA, AB, AC, BB and BC genotypes （P〈 0.05 ）.It was suggested that IGFIR gene might be the main （effect）gene of chicken weight, or it was closely linked to the main （effect）gcne.
