Description
Summary:Hemp (Cannabis sativa L., 97% nucleotide identity to their nearest GenBank accessions. As the growing season progressed, viral incidence and the number of viral species increased. We observed similar and unique viromes between individual cultivars from the same field. Given the prevalence of BCTV in the virome and its prevalence across the western United States, 13 genotypes of hemp were screened for resistance to this pathogen. Two genotypes (4587 and 4710) had a lower BCTV copy number and disease index than others. Our study provides initial evidence of the diversity of viral communities in hemp across Colorado and provides impetus for developing accurate detection methods and screening for host resistance.
