Mission & History


The Peninsular Station serves as a field laboratory for fruit specialists.  Here they develop pest control programs and conduct other research to improve yields and quality of apples, cherries, grapes, and raspberries.  Small grains and vegetable research is also conducted at this facility.

The Peninsular Station is also 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.
