There are over 100 green-when-ripe tomato varieties and as is often mentioned on the Growing Tomatoes forum, it is almost impossible to name a variety from a photo simply because at least 50 of that 100 look the same. The link below provides photos of most of the 100 varieties and you can go through the photos to compare with yours to see if that helps. But yes, if they were a heirloom variety and assuming there was no cross-pollination when you grew them then the odds at 9:1 that they will reproduce true from the seed you saved.

Hi Susan, A tomato is ripe for seed saving when it is ripe to eat. (Some things must be over ripe, eggplant and cucumbers are examples of that.) It is best to wait until a tomato is fully ripe to save seeds. A bit over ripe is fine. If really under ripe, you will get no viable seed. If a bit under ripe, you may not get as many good seed, but will still get some that are usable. It is easiest to think of the fruit as a womb, and waiting for the seeds is like a pregnancy. You want to go full term for the healthiest babies. Tomato crossing rates are very low. It does happen though. So it is best to save seed from multiple fruit. The chances of all the fruit being crossed is very low so you know you'll have true seed. Hope this helps, Remy

Some very nice pictures there, I am growing some Roma too and those pics may give me some help as to when they are ripening, they seem to go from a lighter to a darker green first. Cannot really off any advice on the toms though, at least not expert advice. All I can suggest, on the positive side is the that the plant knows best and decided to drop those fruits, perhaps because it had such a big crop? Too may mouths (tomatoes) to feed? But why would it drop them? Well maybe if they rotted on the plant the whole plant might become diseased? Sacrificed for the greater good? I am just guessing of course, I am a novice grower, just trying to apply some tomato logic. I guess it remains to be seen how the plant will get on. There is picture of my Roma in the linked blossom end rot thread. I am just wondering how long that big one has tell it ripens. I think some of mine fell off last year too, but they were all hit by disease. I would consider ripening ones falling off a success, none of mine got that far before disease set in!! I'm in the UK though and they are outside, so I was never expecting much, I started earlier this year and am hoping things will be better this year as the weather has been better (sunnier) too. All my plants are twice the size as well, it's like a jungle out there!!! Best of luck with the rest of them!! Here is a link that might be useful: my pic in blossom end rot thread

Hi liz - here is a previous discussion on it that should answer your question. Dave Here is a link that might be useful: Why do seeds sprout inside a tomato?
