摘  要：
为了挖掘清平猪妊娠期短和产仔数多等优良繁殖性状的遗传背景,在清平猪与大白猪杂交后的F1代和F2代黑猪群体中进行了ESR、FSHβ和PRLR与该群体繁殖性能的关联性分析。结果显示:(1)FSHβ基因在F1和F2群体中的A等位基因与B等位基因的基因频率相近;ESR在F1和F2群体中的优势基因均为B等位基因;PRLR基因在F1群体中的优势基因为C等位基因,在F2群体中C等位基因与T等位基因的基因频率相近。(2)FSHβ不同基因型对F1群体的产活仔数和F2群体的总产仔数、初生体质量、断奶仔猪体质量和3周龄体质量等重要繁殖性状均有显著影响。(3)ESR不同基因型对F2群体妊娠期长短的影响表现为AB

摘  要：
In order to explore the genetic background of short gestation period and high litter size of Qingping pigs,correlation analysis between ESR,FSHβ and PRLR genes and the reproductive performance in F1 population and F2 black pigs of Qingping pigs× Landrace hybrid was carried out.The results showed that:(1)The gene frequency of A and B allele of FSHβ was similar in both F1 and F2 populations,while the predominant allele of ESRin both populations were B allele.The predominant allele of PRLRin F1 populations was C allele,and gene frequency of C and T allele in F2 population was similar.(2)Different genotypes of FSHβ had significant effects on the number of live piglets in F1 population,and on the total number of litters,birth weight,weaned piglet,and weight at 3 weeks of age in F2 population(P<0.05).(3)Effects of different ESR genotypes on gestation period in F2 were in the order of AB
