ABSTRACT

The aim of this study was to evaluate genetic diversity within and between lines at the Norwegian live poultry gene bank as well as assessing the conservation value in an international context. Eight lines including the national breed, Jærhøns, were genotyped with the 600K Affymetrix^® Axiom^® Chicken Genotyping Array. The white egg layers were generally more inbred than the brown layers. Comparative analyses were carried out with 72 international populations of different origins. The lines that were last bred for commercial production in Norway, Norbrid, are clearly separated from the rest of the international set and more closely related to the current commercial lines. The brown egg layer Norbrid 7 has the highest relative contribution to genetic diversity. The Norwegian genebank lines are of conservation value in a national and international perspective, as they all add genetic diversity to the global set.

摘要

这项研究的目的是评估挪威活家禽基因库中品系内部和品系之间的遗传多样性，并评估国际背景下的保护价值。八线，包括国家品种，Jærhøns，分别用600K的Affymetrix基因分型^®公理^®鸡基因分型阵列。通常，白色蛋层比棕色蛋层更近交。对来自不同来源的72个国际人口进行了比较分析。挪威最后一次育种用于商业生产的品系是诺布里德，与其他国际品系显然是分开的，并且与当前的商业品系关系更为密切。棕色蛋层Norbrid 7对遗传多样性的相对贡献最高。从国家和国际角度看，挪威种质库系具有保护价值，因为它们都为全球种系增加了遗传多样性。
