| 摘 要： | 通过PCR-RFLP方法,检测外来品种大约克猪和江苏地方品种梅山猪、二花脸猪、姜曲海猪以及培育品种苏钟猪共144头,结果表明PGC1基因第8外显子序列经Alu I酶切后存在AA、AT和TT 3种基因型,其中大约克猪中AA基因型占优势,A等位基因频率为0.7,而江苏地方品种猪中,TT占绝对优势。分析PGC1基因型与肉质性状相关发现,AA基因型猪的肉色L、失水率均极显著低于TT基因型(P<0.01);TT基因型猪的蒸煮损失、剪切力和肌纤维直径均极显著低于AA基因型(P<0.01)。

| Abstract: | The genetic variations of the eighth exon of PGC1 gene were detected with PCR-RFLP-Alu Ⅰ in 144 pigs including Meishan pig,Erhualian pig,Jiangquhai pig,Suzhong pig and Yorkshire.The results showed that there were three genotypes(AA,AT,TT) and the genotype of AA was dominant in Yorkshire,and the frequency of allele A was 0.7.In the Jiangsu native breeds,the genotype of TT was dominant.The relation of PGC1 gene and meat quality traits indicated that the value of meat color L and water-losing rate for AA genotype pig were lower than those of TT genotype pig(P<0.01).Braise rate,shear force and muscle fiber diameter for TT genotype pig were lower than those of AA genotype pig(P<0.01). |
