Overview
Hemp (Cannabis sativa L.) is used to manufacture a variety of products including fabrics, construction materials, seed-based foods, and medicinal oils. Extensive research is required to further utilize hemp as a modern fiber, oilseed, medicinal, and industrial crop. Currently, there is limited access to hemp genetic resources, a lack of knowledge of the genetic architecture underlying priority traits, and few genetically stable cultivars are available.
Our team is excited to work on some of the challenges associated with hemp production such as regulatory compliance, seed shattering, and stand uniformity. Specifically, we are working with other USDA and university partners to evaluate the diverse USDA hemp collection for important secondary metabolites, seed and fiber quality, and adaptation to an array of environmental stressors.
Please reach out if you’re curious about this research and would like to learn more. Our multidisciplinary team is looking for additional collaborations, ideas, and engaged learners.
