‘PC 7903-2’, more commonly known under the trademarked name, Cowiche™, is a sweet cherry variety released in 2007 by the Washington State University Sweet Cherry Breeding Program for fresh market production. In Pacific Northwest production areas of North America, Cowiche™ blooms moderately late, generally 4 to 7 d after ‘Bing’ (midseason industry standard), whereas harvest timing is usually 3 to 7 d later than ‘Bing’. Cowiche™ is vigorous and has an open canopy with a more pendant growth habit and slightly higher precocity than ‘Bing’. Its productivity on Gisela® 5 rootstock is similar to Chelan™’s but higher than that of ‘PC 7417-9’. Cowiche™ produces very large red–purple fruit that are firm and have excellent eating quality characterized by high soluble solids and acidity. Consumer taste panels have described its flavor as “intense.” Cowiche™ is not self-fertile, but its uncommon S-allele combination, S5S9, currently places it in the same incompatibility group with only one cultivar, Krupnoplodnaya, making it cross-compatible with any moderately late-blooming commercial cultivar.
