Did you know the USDA has an official blueberry genebank? Plants are collected, grown and protected at a USDA Agricultural Research Service facility in Oregon.

Familiar blueberries and their lesser-known wild relatives are safeguarded by U.S.Department of Agriculture (USDA) scientists and curators at America's official blueberry genebank. The plants, collected from throughout the United States and more than two dozen foreign countries, are growing at the USDA Agricultural Research Service NationalClonal Germplasm Repository in Corvallis, Oregon. 

The blueberries are maintained as outdoor plants, potted greenhouse and screenhouse specimens, tissue culture plantlets, or as seeds, according to research leader Kim E. Hummer.

The genebank's purpose is to ensure that these plants, and the diverse genepool that they represent, will be protected for future generations to grow, enjoy, study and improve. For example, plant breeders can use plants in the collection as parents for new and even better blueberries for farm or garden.

Blueberries and several other small berries are among the fruit, nut and specialty crops housed at the Corvallis repository, which in turn is part of a nationwide, ARS-managed network of plant genebanks.



Likely the most comprehensive of its kind in the United States, the blueberry collection nevertheless continues to expand, Hummer says. Some acquisitions, referred to as accessions, are donations from breeders. Others are acquired through collecting expeditions, which have taken plant explorers to Russia, China, Ecuador and Uruguay, among other places, as well as throughout the United States to find new blueberry plants for the repository.

The collection includes species of wild blueberries native to the Pacific Northwest that have pigmented flesh or pulp. Some breeders are trying to breed some of these species into the familiar highbush blueberry that has a white interior, Hummer says.
