摘要

本研究的目的是评估挪威活禽基因库内和系间的遗传多样性，并评估其在国际背景下的保护价值。采用600K Affymetrix®Axiom®鸡基因分型阵列对包括国家品种Jærhøns在内的8个品种进行基因分型。一般来说，白蛋比棕色蛋近交系更强。对72个不同来源的国际种群进行了比较分析。最后在挪威诺布里德进行商业生产的品种，与其他国际品种明显分开，与目前的商业品种关系更密切。褐蛋鸡诺杂交7号对遗传多样性的相对贡献最高。从国家和国际的角度来看，挪威基因库系具有保护价值，因为它们都为全球基因库增加了遗传多样性。

Assessing the genetic diversity conserved in the Norwegian live poultry genebank

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.
