摘要: 为深入挖掘淳安花猪优良种质特性,运用PCR\|RFLP方法,对淳安花猪的雌激素受体(ESR)基因、促卵泡激素β亚基(FSHβ)基因、生长激素(GH)基因、黑素皮质激素受体4(MC4R)基因、兰尼定受体1(RYR1)基因进行分子遗传学检测,结果表明:淳安花猪MC4R,RYR1基因分别只有1种基因型AA,BB;ESR,GH基因各有2种基因型AB和BB;5个基因的基因型分布在淳安花猪群体中符合哈迪-温伯格平衡(P>0.05)。结果提示,淳安花猪具备繁殖性能较好、瘦肉率较低、生长周期较长、抗应激性较好等遗传特性。

Abstract: This study aimed to explore the germplasm characteristics of Chunan spotted pig. By PCR\|RFLP method, estrogen receptor (ESR) gene, β subunit of follicle stimulating hormone (FSHβ) gene, growth hormone (GH) gene, melanocortin receptor 4 (MC4R) gene and ryanodine receptor 1(RYR1) gene were detected. The results showed that MC4R and RYR1 gene had only one kind of genotype, AA or BB respectively. ESR, GH gene had two kinds of genotypes, AB and BB. Genotype distributions of all genes conformed to Hardy\|Weinberg equilibrium in Chunan spotted pig populations(P>0.05). The findings indicated that Chunan spotted pig has genetic characteristics such as better reproductive performance, lower lean meat rate, longer growing period and better stress\|tolerant.
