Open Pollinated Corn

[mortality]

Please forgive a complete corn growing novice, this question.
I understand what an open pollenated corn looks like, how are the other types different?

open pollinated means that it grows true to type,
not like a hybrid corn.
it you are wanting to save the seeds from a corn
and are not making a hybrid for the reasons of plant breeding,
then you likely want an open pollinated one.
