Chestnut production in the northwestern United States
2000
Olsen, J.L.
The chestnut (Castanea Mill.) industry in the northwestern United States is in its relative infancy, with most orchards being less than 10 years of age. Currently there are an estimated 300 acres (121 ha) in Oregon and Washington. California has about 500 acres (202 ha) in chestnuts. Current worldwide production is over 500,000 tons (435,600 t). China is the leading producer with 40%, followed by Korea at 15%. Italy, Turkey and Japan grow 10% each, while France, Greece and Spain grow 4% each. The United States, Chile, Argentina, New Zealand and Australia each grow less than 1%. The value of chestnuts imported into the United States is estimated to be $10 to 15 million annually. Domestic producers hope to displace some of the imported chestnuts in the marketplace. The leading variety being grown in the western United States is 'Colossal,' a hybrid between european chestnut (C. sativa Mill.) and japanese chestnut (C. crenata Gillet). 'Dunstan' hybrids are chestnut blight (Cryphonectria parasitica Murr.) resistant, and were bred in Florida using chinese chestnut (C. mollisima Blume) and american chestnut (C. dentata Marsh. Borkh.) parentage. Prices received by chestnut producers in the northwestern United States have ranged from $1.20 to $7.00/lb ($2.64 to $15.40/kg). The marketing of chestnuts has been through brokers into wholesale markets, farmers markets, mail order and direct sales through catalogues and World Wide Web sites.
