Our kitchen garden & rogue tomatoes?

Hi All,

We restarted our kitchen garden a couple of years ago during the first lockdown. Seeds were hard to find so I raised a tin of old seeds I had kept sealed and in our spare fridge in the garage (alongside the Sauvignon Blanc!). Though some were as much as 12 years old they all germinated just fine and produced healthy plants even the parsnip seeds they say are only good for 2 years). We couldn't go out to buy compost so I riddled compost from the heap and the seeds really loved it! For the plants that ideally like rich fertile/manured ground, I dug in well rotted grass compost (I create a new pile each season in a spare bit of land) and they did really well too.
We're doing the same this season but now to my question, many of the pots and trays have a tomato growing in them, including those sown at different times to the tomatoes (so it's not dropped seed during sowing). So presumably it's seed from the compost heap. But it's odd because we always eat the whole tomatoes, we don't deseed, and only sieve cooked tomatoes for sauces so presumably those seeds would be viable. Now I'm a few tomatoes short in the greenhouse. Could the compost freebies be used or will they not come true for any reason? If somehow they are from tomatoes we've grown previously they would be Gardeners Delight, Super Marmande, San Marzano, Moneymaker, or we once grew Ferline.
Hopefully someone will know and maybe our use of old seed and homemade compost will help others 
Thanks All
P

    If you've got the space, I'd grow them. Sometimes they're better than the ones you sow.

    They may not be true to the original plant, but if you need a few extras, let them grow  :)

    The seeds don't digest, so whatever eats them will turn them out again, which is often how they show up unexpectedly. 
    I grow tomatoes from the seeds of any leftovers in the fridge - I think tinned tomatoes are cooked, but I don't know how long for, so the seeds from those may not be viable.

    I get tomatoes growing from the compost. It must be either a few seeds from the kitchen waste (I eat them but a few get left on the chopping board and scraped in to the compost caddy) or from the occasional fallen/damaged fruit off the plants.

    Thanks All,
    I must try some seeds from a bought tomato as I am short of cherry tomatoes this year and I will miss my gardeners delight!

    Gardeners Delight seems to be very varied nowadays @Prologica. I seem to remember some debate about it on the forum a while ago.
    You can certainly use seeds from a tomato you've bought. I've been doing that for the last couple of years. My daughter kept buying Piccolo toms - the ones on the vine [ridiculous!] so I saved some, and we had a great crop last year. They're being grown again this year. They also seem quite true to the parent.  :)

    Tomatoes very rarely cross without help so anything that wasn't an F1 will grow true to type. an F1 could give you a bit more variation but it'll still be an ok tomato.

    Added to that, commercially-grown tomatoes have probably been grown under cover with large numbers of plants of the same variety, so limited scope for cross-pollination.
