The only problem you will have is if you plan on saving the seed to plant for next year. I believe the 2 you mentiond are hybrid corns anyways, so they wont be true next year if you are saving seed from this years crop. So go ahead and plant if all you are worried about is this years ears. The Incredible wont be red this year. Hope this helps.

Uh, when field corn pollinates a few grains of my sweet corn, the crossed kernels are very much like field corn that first year. So I would try to separate the pollination times some. Also you don't want them both ripe at the same time. I believe Incredible takes almost a week longer.

Concur with Wayne. If they mature at the same time, you will get mixed grains of red. The bicolor incredible will have some redish grains and the red will show some grains from the bicolor. Corn is one of the few vegetables that does this and its because we actually eat the seeds which are cross pollinated. Both are excellent sweet corns, so you probably won't notice any loss of quality, but appearance will be affected. I often create my own bicolors by by interplanting yellow and white sweet corn.

Just a quick note -- I grow Ruby Queen every year, it is one of my favorites.

I'm not familiar with Incredible. HOWEVER, if it is a Sh2 or ShQ corn, you should isolate it by 50 feet from the Ruby Queen, which is an SE corn. When SE and Sh2 or ShQ corns cross-pollinate, the kernels are very tough and starchy, even when the corn is picked fairly young. Trust me, I've had this happen, it is NOT a good thing. If the Incredible is an SE corn also, it will mix the colors as said above, but the flavor and quality won't be affected.

And yes, when you grow Ruby Queen next to a regular corn, you get mixed colored ears in the Ruby Queen. I've never seen a solid red kernel in the other corn, but I have seen a few with fine red lines or stripes across the top of the kernel, similar to the pattern one commonly sees in ears of ornamental corn.

Actually, Incredible is an se yellow.....not an sh2.
