Not really. The most common thing you hear is that the black dogs have better noses but I'm not sure if that's true or not. There is such a thing as linked genes but what genes are linked with which isn't known.
In certain populations there are some generalizations you can make like in the US black isn't allowed in the show ring so if you see a black dog there it is bred to hunt. In NZ the black dogs until recently all traced back to one particular black dog imported from Oz. More recent imports make the generalizations in NZ less accurate.
