A public mid-density genotyping platform for North American Atlantic salmon (Salmo salar L.)

Genomics-enabled selective animal breeding has become common in recent years, prompting a growing need for diverse genotyping tools that facilitate collaboration among research groups while meeting specific programme needs and objectives. Here, we report the development of a medium-density amplicon panel (DArTag) of 2,950 loci for North American Atlantic salmon. It includes loci distributed across the genome and loci useful for distinguishing the continent-of-origin, parentage, and sex determination. This mid-density panel offers more cost-effective and rapid genotyping capabilities for Atlantic salmon researchers and breeders. The open access provided by this platform facilitates comparisons and enhances data reusability across projects, institutions and countries that use different genomic tools for genotyping. This genotyping panel can make routine genotyping a viable tool for breeding and research programmes.
