As i've sent some seeds out to a few of you, I thought i'd do a sticky thread, telling the story of the variety and somewhere we can post progress reports/pics during the season 
The Manx Marvel was bred on the Isle of Man to withstand the sometimes harsh conditions of a island in the middle of the Irish Sea.
It had seemingly disapeared from the island, but back in 2007 Dr Russell Sharp managed to obtain 4 seeds from a seed bank in America.

On the uk forum we managed to get hold of some seed from a Canadian member, we then divided it between 7 members, just 5 seed each.
We decided to grow it at different locations to lower the risk of loosing it all to blight or some other disease.
After a couple of years we now have a few thousand viable seeds between us, i've been distributing mine and growing on more plants.
Also had a meeting with a commercial tomato and chilli nursery, they are trialing the plants with a view to marketing them, seemed daft to go to all this trouble and not do something with it.
The plant's were grown in isolation, although cross polination is unlikely, we weren't taking any chances.
It's a well built stocky plant, we found it was best grown outside, didn't do too well in a greenhouse.
This is a quote from one of the members involved in the project
So they we go, lets plant and compare

I was the last of our secret squirrel gang to start them off, sowing on 24th April. I had three seeds and only two germinated. These two grew very quickly, and I kept them in the greenhouse all the time. I started picking ripe fruit off them on 31st August (they actually beat some of my other varieties to ripen even though those had been sown 6 weeks earlier!)
We were not really sure of its growth habit, so the two main plants in my greenhouse I treated one as a cordon the other as a bush. Although they grew quickly the greenhouse plants never looked that happy compared with my other varieties. So maybe they don't like the indoor heat. They still produced respectable yields. The Cordon plant was the best, it had a few more fruit and on average they were bigger by some 25%. So between us we are certain that Manx Marvel should be treated as a Cordon.
The cordon plant's sideshoots I grew on and planted seven of them outdoors on 26th July. These outdoor plants grew even faster and bigger than the inside ones. They were much better in terms of yield and plant size compared to my other outdoor varieties (Ferline and Rosada which I'd started off much earlier).
Sadly my outdoor Manx Marvel's were wiped out by Blight in September. That was a shame as they were heavily laden with fruit at that point and none had ripened. I still managed to salvage 5.5kg of green fruit off them before I had to destroy the plants to stop Blight spreading. Given a bit of space and an earlier start then I reckon Manx Marvel will be a very heavy cropper outdoors.
So they we go, lets plant and compare
