Can different corn types grow in the same field?

The different types of sweet corn, or field corn, should be separated by at least 250 feet or by at least 14 days in maturity. The pollen from one corn plant will influence the kernel of another plant. Since the different types of corn use different genes to control the sweetness, different types will produce kernels of normal field corn. Yellow and white sweet corns should also be separated for this reason.
