I've not grown either type but was under the impression that Marketmore was an outside type ridge cucumber where the female flowers need to be fertilised. If you're growing it inside then you'll need to perform cucumber sex! Get busy with that paint brush! But if they're outside they should be OK - doesn't hurt to give them a help though!

I've just googled the burpless ones and note that they're the same so you don't want to remove any of the flowers as they need to be fertilised. (there are some varieties where the cucumbers become bitter if fertilised)

I'd suggest helping them out a bit but otherwise pretty much leaving them alone and enjoying your salads.
