    I think this long-read assembly is a great improvement against the previous short-read version available to the community to date. The assembly metrics are good, the dataset public, and there is good quality control all through the process. The manuscript is well written and the protocols are well explained. The data is public and the new assembly of interest to the community.

    However, I think the assembly has a limited interest for the research and breeding community without a gene annotation, which is not part of the manuscript. Since the authors have the data (e.g. iso-seq) and expertise, I do not understand why it has not been included in first place.

    Red clover is one of the most important forage crops in the world. The gametophytic self-incompatibility resulting in inherent high heterozygosity is the big challenge to get a high quality genome sequence using traditional short-read based genome assemblies. The author Bickhart et al used the long-read based assemblies method to get a high quality genome which significantly reduced the number of contigs by more than 500-folds, and improves the per-base quality and the genome size to 413.5 Mb matching well with the predicted genome size. This assembly accurately represents the seven main linkage groups, and it will help scientists to understand the origin of condensed tannins biology pathway in the leaf forages and to facilitate gene discovery and application of biotechnology to increase the nutritional value.

    I strongly support the editor to accept this manuscript to be published.
