I try not to ask questions unless I've exhausted all other means of finding the answer but I can't find the answer to this question.
As near as I can tell, if you save seeds from a hybrid and replant them, the results may not be true. Since there's so many varieties of tomatoes out there I'll use Early Girl as an example. I know Early Girls have been around a long time and you can buy seeds in just about any place that sells seeds every year. Where do the seed companies get their seeds ?
If the variety is stabilized why is it still labeled as a hybrid ?
