Moneymaker springs to mind as a heavy cropper but well worth taking into consideration best flavour tomatoes too.
Dont grow cucumbers alongside tomatoes - they need totally different conditions for maximum effect.

I've always grown Alicante in the greenhouse and they have a lovely flavour, Yifang. Ours have produced pounds and pounds this year----or should that be kilos and kilos! I don't do metric unless forced!! Annie
I also grow Gardeners delight in the greenhouse, and outside in a sheltered spot, and they have a really old-fashioned flavour---just like tomatoes used to taste!!

I grew Shirley again for about the seventh year. Really good imunity to viruses. Exellent crop but only downside is that the skins seem to be a little tough. Greenhouse cucumbers can be a problem with spider mite as I can't keep the humidity up.

I usually grow the old favourites too but the plants have had blight over the last few years so this time I grew from seed a tomato with higher blight resistance - F1 Fantasio - they've been great, lots of toms and nice flavour. Blight has finally set in though :-( but the plants are almost exhausted anyway so not worries really.
