Worldwide, Mexico is the leading producer of blackberries, with nearly the entire crop being produced for export into the off-season fresh markets in North America and Europe. The Mexican market is almost entirely from the cultivar 'Tupy' (often spelled 'Tupi', but the EMBRAPA program in Brazil from which it was released prefers the 'Tupy' spelling). In the US, Oregon is the leading commercial blackberry producer, producing 42.6 million pounds on 6,180 acres (25.0 km2), in 1995[16] and 56.1 million pounds on 7,000 acres (28 km2) in 2009.[17]
