"Mortgage Lifter" tomato......saving seed?

[greenishfing]

Earlier this year, when my own tomato seedling were showing their suicidal tendencies, I bought a rather leggy tomato plant with flowers on in desperate need of potting on in a local charity shop. It's name was "Mortgage Lifter". I'd never heard of it.

It has thrived and I have now had three marvellous big tasty beefsteak tomatoes with plenty more green ones following on.

I am so impressed with it that I would like to save seeds for next year if possible. I have read that it is a heirloom variety. My question is that as it is in a greenhouse with lots of other varieties of tomato if I just kept a tomato for seeds would they be the same as the original plant or would it have cross-pollinated with other varieties and would I end up with something completely different?

My response - it is always worth a shot. But if you still have some flowers that you can isolate and pollinate it is worth sealing them off and trying for a last self pollinated fruit to save seed from. The bees and insects are a lot more active than we give them credit for.

Not all heirloom varieties cross with each other, you can usually tell by the shape of the flower. Can you do a close up photo of a flower and we should be able to help you.
