''Field corn'' varieties are grown primarily for livestock feed. Varieties grown for human consumption contain a gene that increases the sugar content and are known as ''sweet corn.''

In 1983, [[Barbara McClintock]] won the Nobel Prize for Physiology or Medicine for studies of the genetics of corn, specifically her 1948 discovery of mobile genetic elements in the corn genome.

In recent years, Monsanto produced and began selling corn seed which has undergone artificial genetic modification.  This corn is advertized to grow better, resist disease, and resist Glyphosate, the active ingredient in Monsanto's Round-Up and other herbicides. [[Genetic Engineering|Genetically modified]] corn is estimated to account for at least 90% of the American corn market today.
