Depending on what it is, you may end up with something very similar to the F1. I'm no expert in this by any means, but I've saved a few seeds here and there from produce and from F1 plants. It doesn't hurt to grow them out and see what you get. I tried growing out F2 pepper seeds a few years ago and I kept getting 3 different types of peppers. Of the 3, the ones I really liked were seedless, so unless I took cuttings, I could never keep growing those. I've saved seed from white marigolds and they would never germinate. I've read that tomatoes grown from Campari F2 seeds are just like or very close to the F1. It is fun to try...I usually have some kind of experimental planting each season, but on a very small scale..

I think I can answer my own question now, lol-at least in my own garden. Limerock Ruby and Autumn Blush produce a few collectible seeds, Passion apparently does not produce anything I can discern.

Carolyn, why not tell GardeningHarpist about growing out Ramapo hybrid? ***** Can do. For a while Ramapo F1 went out of production and since it was a fave of quite a few folks I decided to dehybridize it, aka, make selections, to see if I could develop an OP version that was close to the original. I had available to me some Ramapo F1 seeds as well as a 6 pack of Ramapo F1 plants that a friend in NJ sent to me, b'c several growers had sandbagged seeds, worried that Ramapo F1 might go out of production. Ramapo F1 has two parents as I indicated above. I saved seeds from F1 fruits, now called the F2 seeds, planted out the next year, I think only 4 plants and also planted out known Ramapo F1 plants from the seed I had for comparison sake. 3/4 plants walked and talked and tasted like the F1 and the 4th plant was a throw back to one of the parents. I saved seed, now F3 seed from one of the F2 plants that compared well with the original F1 and at that point I felt that the F3 seed was pretty darn good as an OP and distributed seed to quite a few folks. One person formerly was a commercial tomato grower in NJ and he also thought it was pretty good, and as the years went by folks shared seed with others and I know it was doing fine out to the F6 generation. Ramapo F1 was developed by Rutgers U in NJ and they've now made the original F1 seed and it's available from Rutgers directly and also from Harris Seeds in Rochester, NY. Usually it takes more generations than to the F3 to get something genetically stabilized so I got lucky on this one. The variety now known as OTV Brandywine I had to take out to the F5 before it was stable. Carolyn

Growing plants from hybrid seeds is lots of fun because you can sometimes get variations that are quite wonderful. You NEVER get little "Frankenstein-monster" plants, lol. Hybrids may or may not come true from seed. The flower colors might be somewhat different, or the shape or count of the petals might be different, or the leaves might be more shiny, or a little less pointed, the height might be different by a few inches, etc. Those are probably all the expected differences you could see....if you notice them at all. You've got a 50/50 chance that the seedlings will be different from the parent plant....either they will be or they won't be different. Growing the seeds of a hybrid is actually a lot like the children of one couple. Sometimes they are all identical...each child's face has the same features as it's brothers and sisters, or sometimes each child is different and looks like any of the grandparents, or even it's great-grandparents. Enjoy growing the seeds of a hybrid plant. When the seedlings grow to maturity you may find that you're in love with the whole batch, or some may be more appealing to you than others. Keep your favorites and share or compost the rest. Enjoy your garden!
