The Germplasm Resources Information Network - Canadian Version (GRIN-CA) web server provides germplasm information about plants within the Plant Gene Resources of Canada (PGRC) division of Agriculture and Agri-Food Canada (AAFC). GRIN-CA was created from the United States Department of Agriculture's National Plant Germplasm System (GRIN). Some modifications have been made to the original GRIN system but in general searching on either system should be very similar.
