Spinach (Spinacia oleracea L.) is an economically important leafy vegetable crop in many countries, and approximately 14,000 ha (35,000 acres) are grown annually throughout the United States (25) for fresh and processed (frozen and canned) markets. The annual crop value in the United States is approximately $70 million (25). Major spinach production states include California, Texas, Arkansas, Oklahoma, Maryland, Virginia, New Jersey, and Colorado (32).Spinach apparently is native to central Asia and has been cultivated for more than 1,300 years (46). Spinach is a member of the Chenopodiaceae and is related to Swiss chard, sugar beet, and table beet. The plant produces a compact rosette of leaves and bolts (ie, produces a seed stalk) in response to temperature and photoperiod. Spinach is usually dioecious, producing either male or female flowers. The majority of the spinach seed used in the United States is produced in the Pacific Northwest, where long days correspond with moderate temperatures.
