      Editor’s Assessment

      Hybrid genomes are tricky to assemble, and few genomic resources are available for hybrid grapevines such as ‘Chambourcin’, a French-American interspecific hybrid grape grown in the eastern and midwestern United States. Here is an attempt to assemble Chambourcin’ using a combination of PacBio HiFi long-reads, Bionano optical maps, and Illumina short-read sequencing technologies. Producing an assembly with 26 scaffolds, an N50 length 23.3 Mb and an estimated BUSCO completeness of 97.9% that can be used for genome comparisons, functional genomic analyses, and genome-assisted breeding research. Error correction and pilon polishing was a challenge with this hybrid assembly, but after trying a few different approaches in the review process have improved it, and as they have documented what they did and are clear about the final metrics, users can assess the quality themselves.

      This assessment refers to version 2 of this preprint.
