GRIN-U is a collaborative project to provide open access to educational and training content on plant genetic resources (PGR) conservation and use.

The project is funded by a grant from the USDA National Institute of Food and Agriculture (NIFA), and includes investigators from ARS, Colorado State University, Iowa State University, and a private contractor.

As part of the GRIN family of products, GRIN-U contains visual (videos, virtual tours, podcasts) and printed (e-books, infographics, manuals) materials on a variety of topics related to PGR management and plant genebank operations.
