Interpretive Summary: Small public breeding programs focused on specialty crops have many barriers to adopting technology, particularly creating, and using genetic marker panels for genomic based decisions in selection. Therefore, a team from Cornell University, North Carolina State University, Jamaica, and the USDA, ARS, U.S. Vegetable Laboratory developed a marker panel of 3,120 DNA markers distributed across the sweetpotato genome for use in molecular breeding and genomic prediction. The creation of this marker panel brings cost-effective and rapid genotyping capabilities to sweetpotato breeding programs worldwide. The open access provided by this platform will allow genetic data sets generated on the marker panel to be compared and joined across projects, institutions, and countries. This marker panel has the power to make routine genotyping a reality for any breeder of sweetpotato.

Technical Abstract: Small public breeding programs focused on specialty crops have many barriers to adopting tech-nology, particularly creating, and using genetic marker panels for genomic-based decisions in se-lection. Here we report the creation of a DArTag panel of 3,120 loci distributed across the sweet-potato genome for use in molecular breeding and genomic prediction. The creation of this marker panel brings cost-effective and rapid genotyping capabilities to sweetpotato breeding programs worldwide. The open access provided by this platform will allow genetic data sets generated on the marker panel to be compared and joined across projects, institutions, and countries. This genotyping resource has the power to make routine genotyping a reality for any breeder of sweetpotato.
