I am not that ambitious as to create a new variety.  The reason for
selecting 3 ears is that between eating time and seed time, something might
happen to a single ear that would cause it to be unusable or gone.  2 is
back-up and 3 is back-back-up.

Subject: Re: [nafex] OT a bit- Saving hybrid seed (corn)

This year, all your corn plants are pretty much genetically identical, so it
doesn't matter how many plants you save seed from. In future generations,
number of plants will be an issue, as the F2 and later plants will be
genetically different from each other. 

If you want to create a variety that's a population, one hybrid won't
provide enough diversity. It contains the genes of just two inbreds. I can
see crossing it with an heirloom next year to bring in a population's worth
of genes, and then selecting for smut resistance and other traits you like
in subsequent generations, but this would be a pretty involved project, far
removed from, say, the simplicity of saving tomato seeds. I don't want to
discourage you, as amateur plant breeders can accomplish a lot, but breeding
a population takes effort.
