摘要

芬兰地方种鸡(芬兰语:suomalainen maatiaiskana)的起源可以追溯到近1000年前。今天，由芬兰自然资源研究所(Luke)管理的芬兰志愿者爱好者网络维护着表型不同谱系的残余种群。在先前主要组织相容性复合体b座单倍型研究的指导下，我们现在试图使用更密集的基因组取样来描述芬兰长白鸡的遗传特征。一个由101个选择性中性SNP位点组成的新小组被用来调查来自13个假定独特的种群单位的192个个体的遗传变异。个体被划分为K = 11个遗传集群，遗传多样性高，遗传结构模式强，近交水平低。还发现了一种未记载的遗传谱系的证据。通过廉价的SNP分析，这项研究表明芬兰地方种族的遗传完整性持续存在，并代表了丰富的自然(适应性)基因组变异资源。

Heritage Finnish Landrace chickens are genetically diverse and geographically structured

ABSTRACT The Finnish Landrace breed of chickens (in Finnish suomalainen maatiaiskana) traces its origins to almost 1,000 years ago. Today, remnant populations of phenotypically distinct lineages are maintained by a network of volunteer hobbyists in Finland, managed by Natural Resources Institute Finland (Luke). Guided by a prior Major Histocompatibility Complex B-locus haplotype study, we sought now to characterize genetically Finnish Landrace chickens using denser genomic sampling. A new panel of 101 selectively neutral SNP sites was used to interrogate genetic variation in 192 individuals sampled from 13 putatively distinctive population units. Individuals partitioned into K = 11 genetic clusters characterized by high levels of genetic diversity, strong patterns of genetic structure and low levels of inbreeding. Evidence of an undocumented genetic lineage was also discovered. Facilitated by an inexpensive SNP assay, this study shows that the genetic integrity of the Finnish Landrace persists and represents a rich resource of natural (adaptive) genomic variation.
