摘要

汉拿马是济州马和纯种马的杂交品种,用于骑马、比赛和肉类生产。因此,需要进行分子遗传学研究,以建立和保护具有工业价值的汉拿马。利用12个微卫星(MS)标记对汉纳马和3个推定亲缘品种(济州马、蒙古马和纯种马)的遗传多样性和群体结构进行了分析。平均等位基因数、观察杂合度(H obs)、期望杂合度(H exp)和多态信息含量(PIC)分别为10、0.767、0.799和0.771。邻居联接树和结构分析表明,汉拉马介于纯种马和济州马之间,受纯种马的影响更大。因此,这些结果可以作为与汉拿马起源相关的马品种(济州马、蒙古马和纯种马)的基本遗传品种关系资源。

Genetic diversity and relationship of Halla horse based on polymorphisms in microsatellites
Halla horse is crossbreed between Jeju and Thoroughbred horses and is used for riding, racing and meat production. Thus, molecular genetic studies are needed to establish and preserve the industrially valuable Halla horses. This study aimed to analyses the genetic diversity and population structure through 12 microsatellite (MS) markers for Halla and putatively related 3 breeds (Jeju, Mongolian and Thoroughbred horses). On average, the number of alleles, observed heterozygosity (H obs ), expected heterozygosity (H exp ), and polymorphic information content (PIC) among all horses were 10, 0.767, 0.799, and 0.771, respectively. Neighbor-joining tree and STRUCTURE analysis showed that Halla horses were between Thoroughbred and Jeju horses, tend to more influenced by Thoroughbred horses. Therefore, these results could be considered for use as the basic genetic breed relationships resource among the horse breeds (Jeju, Mongolian, and Thoroughbred horses) related to the origins of the Halla horse.
