Starting a Vegetable Garden?

I am wondering if you are confusing "genetically mutated" with hybrids. Most of the vegetables and flowers seeds that you get now are hybrids which means that two different types of corn(for example) were crossed to get the seeds that you are planting and what you grow will be different from either parent, but better...that's why they do it. So now, if you try and save the seed from your corn you planted, you will not get the same corn again because it is different from the original cross. The seeds will grow though....If you want to be able to grow from saved seeds you should look for heirloom varieties that reproduce true. Just do a search for heirloom seeds and I am sure something will come up. I have never experienced what you have described as related to garden vegetables...the only exception I can think of is "seedless" watermelon...the pseudo seeds that do form are not viable.
