I've been growing Koralik tomatoes every year for a while now from kept seeds. This year they are fine again, but a few plants from the same batch that I gave to my parents are producing plum-shaped rather than round fruit. It's not a big problem as they're still perfectly edible, but it's odd and I was wondering if anyone knows why this happens? I don't think it can be cross-pollination as mine are fine, so it must be something environmental.
