The Tree Fruit Research and Extension Center is the Washington State University facility dedicated to the tree fruit sciences. Located in Wenatchee-  the primary fruit producing region of the world- the Center features a cooperative, multidisciplinary approach to tree fruit production in the 21st century.

Research programs at the Tree Fruit Research and Extension Center emphasize primarily apples, pears and sweet cherries although some research is conducted on apricots, peaches and plums. Research is also conducted in orchards of cooperating growers throughout the major fruit production areas of Washington. Production and postharvest research by USDA scientists is also conducted in grower orchards and in cooperation with fruit packinghouses.
