dent corn
Dent corn (''Zea mays'' var. ''indentata'') also known as yellow dent corn, Reid's yellow dent corn, white dent corn, or field corn, is a variety of maize or corn with a high soft starch content. It received its name because of the small indentation ("dent") at the crown of each kernel on a ripe ear of corn. It is a variety developed by northern Illinois farmer James L. Reid. Reid and his father, Robert Reid, moved from Brown County, Ohio to Tazewell County, Illinois in 1846 bringing with them a red corn variety known as "Johnny Hopkins", and crossed it with varieties of flint corn and floury corn.〔Kansas Agricultural Extension Service. ''Bulletin 227: Varieties of Corn in Kansas'' (1921).〕 Most of today's hybrid corn varieties and cultivars are derived from it. This variety won a prize at the 1893 World's Fair.
Most of the corn grown in the United States today is yellow dent corn or a closely related variety derived from it.〔University of Missouri, College of Agriculture Food and Natural Resources. (Division of Plant Sciences Corn Extension ). Retrieved 23 July 2013.〕 Dent corn is the variety used in food manufacturing as the base ingredient for cornmeal flour (used in the baking of cornbread), corn chips, tortillas and taco shells. Starch derived from this high-starch content variety is turned into plastics, as well as fructose which is used as a sweetener (high-fructose corn syrup) in many processed foods and soft drinks.
