The Peninsular Ag Research Station is located on Wisconsin’s geographical thumb, the Door Peninsula, with the waters of Green Bay to the west and Lake Michigan to the east. Station staff initiate fruit research and outreach efforts to support local and state fruit industries. Station research staff also coordinate projects with UW-Madison Departments, including Horticulture, Entomology, Agronomy, and Plant Pathology within the College of Agricultural and Life Sciences.
The Peninsular Station is home to the NRSP-6 US Potato Genebank which maintains the world’s largest collection of wild and cultivated potato species. The US Potato Genebank’s mission is to collect, classify, preserve, evaluate, and distribute nearly 5,000 samples of more than 150 potato species. The Genebank coordinates potato germplasm resources for scientists and breeders around the world.
Our Station is also the site of the “The Garden Door”, a cooperative project with the Door County Master Gardeners Association. The Garden Door is a 1 acre showcase flower and landscape garden.
