Koralik tomato query

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.

    It's genetics I should think. Maybe time to start with new seed.

  • Probably you bought F1 hybrids, they won't seed 'true' which means you'll get something from one of its ancestors (much like how your children aren't identical copies of you...)

    I think Koralik are a heritage Russian variety - some of them do produce varied fruits from time to time.  The flavour's usually pretty stable but the shapes vary.  Probably because they're the product of years and years of 'seed saving' and possible cross-pollination.

    If the tomatoes grow and taste ok I wouldn't worry about it.

    Yes, an old heirloom variety 

    Looks like they do well in cooler climates, have good flavour, can cope with a short growing period and are disease resistant.  I'd carry on growing them image

  • Thanks, yes, I wasn't too worried about it, just curious really - as I say they're perfectly edible. They have very good blight resistance too.
