Varieties of Corn for South Dakota

If one should attempt to even mention all the "varieties" of corn that have been or are produced in this state, one would apparently need to close the list with the words "other varieties too numerous to mention." The number of possible varieties is indeed great enough to become confusing. However, within a long term of years, several varieties have been developed that are very well known and that may serve as standards for judging other varieties. They may also become bases for breeding plot systems.
