Dent corn, also known as grain corn, is a type of field corn with a high soft starch content. It received its name because of the small indentation, or "dent", at the crown of each kernel on a ripe ear of corn. Reid's Yellow Dent is a variety developed by central 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 flour corn. Most of today's hybrid corn varieties and cultivars are derived from it. This variety won a prize at the 1893 World's Fair.
