为了更好地利用雪峰乌骨鸡,本文分析了雪峰乌骨鸡群体的隐性白羽等位基因(C,TYR)、显性白羽等位基因(I,PMEL)、扩展等位基因(e,MC1R)、乌肤等位基因(FM,EDN3)、绿壳蛋等位基因(O,SLCO1B3)、羽速等位基因(K,PRLR)的基因型分布情况。结果显示雪峰乌骨鸡群体主要是快羽类型的品种,其中白色羽雪峰乌骨鸡群体中存在隐性白羽和显性白羽两种突变类型。雪峰乌骨鸡乌肤性状的形成与丝羽乌骨鸡的遗传基础一致,绿壳蛋性状的形成同样是由于EAV-HP的插入导致,但是其插入位置与前人研究结果稍有不同。上述结果为雪峰乌骨鸡相关性状的分子标记辅助选育提供了基础,可以加速雪峰乌骨鸡上述性状的选育进程。
In order to make better use of Xuefeng silky fowl, this paper analyzed the relationship between recessive white feather allele (C, TYR), dominant white feather allele (I, PMEL) and extended allele e, MC1R, FM, EDN3, OHSC1B3, and the plume allele (K, PRLR) were analyzed. The results showed that the main populations of Xuefeng Silky flock were fast-feather type breeds, in which there were two types of mutation, which were recessive white feather and dominant white feather. The formation of the skin-forming properties of Xuefeng black-bone chicken is consistent with the genetic basis of silk-feathered black-bone chicken. The formation of green-shell egg is also caused by the insertion of EAV-HP, but its insertion position is slightly different from previous studies. The above results provide a basis for molecular marker-assisted breeding of the relevant traits of Xuefeng Silky, which can accelerate the breeding process of the above traits of Xuefeng Silky.
