Sweet corn (Zea mays L.) is a major vegetable crop in the United States, where over 325,000 ha (800,000 acres) are grown commercially each year (1). About 70% of the hectarage is processed (frozen or canned) and 30% is sold fresh. On-farm value of processed and fresh sweet corn is about $250 to $275 million each. Sweet corn ranks second among canned and frozen vegetables; 454 million kg (one billion pounds) of cut corn and corn-on-the-cob are frozen and 60 million cases are canned annually. Per capita annual consumption of fresh and canned sweet corn is about 3 and 5 kg (6.5 and 1 l pounds), respectively, which reflects a decrease of about 10% in the past decade.
