Doesn't require any genetic engineering to get this result. MOST of the seeds gardeners and farmers purchase now are Hybridized. Hybrids give us incredibly large and healthy crops. But they don't breed true. Save seed from any modern sweet corn and the result will be NOTHING like the crop you grew last year. And no genetic engineering required.
I agree that this is a troublesome issue. It's one of the reasons I shop at
http://www.nativeseeds.org. but it's nothing new and genetic engineering is not even close to the major impact.

Not from THIS issue. By definition, the problem with these seeds is that they don't produce seed bearing crops. Being afraid of them escaping into the wild is like being afraid of seedless grapes escaping into the wild.
I'm not denying that genetic engineering has some frightening possibilities. The biological revolution is going to make the computer revolution look like small potatoes.
BUT, genetic engineering on plants is usually just doing the EXACT same thing that farmers have been doing for thousands of years, just faster and more efficiently. Breeding flowers and plants to get different results is just genetic engineering done slowly. Seedless grapes are a result of breeders taking advantage of a mutation. The mutation happened because of a copying error, or cosmic radiation, or who knows what reason, but the mutation would not have been any different if it had been deliberately genetically engineered.
The
first corn plants (American corn, Maize, not wheat), was probably just a kind of grass that produced some rather big seeds. It bears very little resemblance to "corn on the cob". The Native Americans genetically modified it the slow way until they came up with the colorful corn you see used as decoration.
Sweet Corn is a mutation of that corn that was further developed by the Native Americans. In the 20th century, further mutations, and massive work on hybridization developed the se and sh2 variations, which is probably the ONLY kind of corn you have ever eaten besides pop corn. It is VERY MUCH genetically modified from the original wild grass that was growing 1500 years ago. Just done the slow and hard way.
If you aren't afraid of seedless grapes or corn on the cob, or really, the VAST majority of food grown in this era, then there is no reason to be panicked by what's been done with Genetically Modified crops so far.
I say so far, because we are only on the very edge of actually designing plants. The differences between plants that were bred and plants that were directly genetically manipulated will continue to grow.
