Preliminary screening of hemp germplasm in REP 1 of 2022 USDA phenotyping trial in Research North 010. This method only includes individual samples from Rep 1 and is used to allow/disallow germplasm for distribution. Analysis following UPLC protocol in USDA Hemp Descriptor Manual version 2 (e.g., using shorter run time than in version 1). Samples were run for individual plants with pistillate flowers (3-10 individuals). Samples were taken 5 weeks after terminal flowering initiated following as close as possible to AMS sampling guidelines, although the apical meristem was not always samples (e.g., auxiliary inflorescences were taken because we were also measuring plant height). Technical samples were run as triplicate and this data represents the mean of those three technical values.
