There is no certainty among plant breeders as regards the origin of the corn plant. Certain authorities claim that corn originated in Mexico from a cross between game grass and a cross between a sport of teosinte grass and the original plant. Regardless of the origin of the corn plant we are very sure that great strides have been made in the development of the corn plant and there is no reason why we should assume that further development will not take place.
