I have been growing painted mountain corn for few years now. This was the first year I intentionally separated the painted mountain from all the other corn I grew (over 500 feet away). In the past year I grown the sweet corn, painted mountain and glass gem in the same 15k(?) square foot garden.

Question: do you see the wrinkled kernels? Are those crossed with sweet corn since that's what dried sweet corn looks like?

I only planted the non wrinkled kernels but lots of the cobs still had the wrinkle kernels on them.

There are probably folks here who can respond to this much better than myself, but I would guess this is likely the case. I don't say that because I can identify any cross pollination from the photo, but because corn saved for seeds requires huge isolation distances since it is wind pollinated. More than one variety planted in the same, even large garden, is highly likely to cross. However, there are exceptions. Can you recall if the corn varieties were shedding at the same time? Therein probably lies the answer. Some corn seed savers will plant more than one type of corn in a given area, but varieties that will shed pollen weeks apart. If your 3 varieties did that, shed their pollen at well spaced intervals, than your seed is likely to have remained pure.

Very beautiful corn variety!

Unfortunately for you. Yes, cross pollinated. It is almost impossible to not get cross pollinated corn unless you separate them by a large distance-1/8 mile or longer.

The good news is that if you sort out the wrinkled kernels, you should have a high percentage of what you desire. By having 2 distinct types, it was in your favor. If both were flint types, I would not suggest that.

There may be some Glass Gem crossing in that corn too.

I suspect that I will be dealing with that issue as well, although to a lesser extent - with the same variety. Lot sizes are large in my sub-division, and most of my adjacent neighbors have double lots. No one nearby has grown corn, so I felt confident that use of ear & tassel bags would be unnecessary. Well, the neighbor upwind of me decided to grow corn in his back yard this year. :thHad I seen that, I would have used the bags I had on hand.

There are some yellow and white kernels in my Painted Mountain; since this is the first time I've grown it, don't know if those colors are part of the color palette for the variety. There are no shrunken kernels. I planted quite early, so hopefully PM beat their sweet corn to tassel.
