Tomato varieties - spotting the difference

[HelenH]

I know this may sound like a daft question, but is there any way of differentiating between Gardeners Delight and Moneymaker tomato plants whilst they are at the 5" high stage? I have inadvertently mixed some of them my 30 plants together; hence I'm now unsure which are which ! They all look the same at this stage but when they are bigger will there be an appreciable physical difference between the two varieties?
Thanks
Helen

apart from the size of the fruit, i dont know of any visible differences, ive aways thought that gd throws more vigerous sideshoots, but i could be wrong and it wouldnt show till later on anyway (if at all)
a tip for next year, put one lot in black square pots and the other in brown round ones
