Yes as long as you are comfortable the field corn won’t tastle until the sweet corn is finished then it should be fine.

Maybe someone could do a trial, if they have multiple maize paddocks, where some have hedgerows surrounding them and some don’t.

I’m picking out the seeds by color, and last years plants, maybe 8, some came up all red, some came up mixed, some came up with nice mixed kind of translucent colors. Blue was just an easy example, since some are lite green, the usual white and yellow and some pretty lighter colors, not dark read.
Since I planted random seeds, that I germinated, I’ll need to start over and avoid anything from last year, which cross pollinated.
Your post was good to know why some had scattered seeds and big areas of nothing. Now I know that they didn’t get pollinated, and that was the cause, not just poor soil or bad watering.
I grow these for the experience and ornamental, so the fun continues.

Thank You

Pete,
I’m afraid that is a little beyond my genetics knowledge. My assumption is that the genes that express the multi-colored cobs are still present in the blue seed, so assuming they are an open pollinated seed, and that you don’t have any crossing, you would still get plants that produce multi-colored seeds.
To get a complete blue ear of corn you would need to plant a seed that came from a plant that only produced blue seeds, or cross the right parents first.
But that is just coming from my Biology 101 knowledge of plant genetics.

If I only save one color seeds, the hypothetical blue, the next year, will I be more likely to get that same color, second generation, or would I be likely to just get a variety of colors, yet again?

I’m sorry Roger, I don’t known anything about this method. In your case you will need to hope that you corn is done tastleing and has pollinated before the feild corn has tastled.

What an interesting job!
