摘  要:
采用PCR-RFLP法检测了96只荆江麻鸭THRSPα基因内含子的多态性,并对基因多态性与屠体性状进行关联分析。结果发现,本试验群体中未检测到AA基因型,仅有CC和CA 2种基因型。其中C等位基因频率为0.979 2,为优势等位基因。χ2检验结果表明,该群体处于Hardy-Weinberg平衡状态。最小二乘分析结果显示,荆江麻鸭THRSPα基因内含子CA型个体活重极显著高于CC型(P<0.01),CC型个体全净膛率、胸肌率和瘦肉率极显著高于CA型(P<0.01),其他性状间差异不显著(P>0.05)。

摘  要:
The polymorphisms of the intron of THRSPα genes of 96 Jingjiang ducks were analyzed by PCR-RFLP method,and the association of the polymorphism with carcass traits was investigated simultaneously.The results showed that only genotypes CC and CA rather than AA were observed.The gene frequency of allele C was 0.9792,which was more predominated than allele A.Further more,χ2 analysis showed that the population was in Hardy-Weinberg equili-brium.The results of least square analysis showed that the body weight of CA ducks were extremely huge than those of CC(P<0.01),while the rations of net-wide-bore,chest muscle and lean detected in ducks with CC genotype were significantly higher than those of CA genotype(P<0.01).No significant difference was detected in other carcass traits(P>0.05).
