Back 20 or 30 years ago, I used to read that you shouldn't plant black and red raspberries together because the blacks would carry diseases that they would transmit to the reds.  Here in Indiana, you see blacks growing wild but not reds, so it at least seems possible that blacks could tolerate and transmit diseases that would be devastating to the reds. However, I wasn't able to find any mention of this idea on websites that discuss raspberry diseases.

   As many of you know, I sell black raspberry plants.  We've all heard of
frequently asked questions and the one I hear most often is, "I heard that
black raspberries and red raspberries shouldn't be planted close to each
other; why is that?"

   I'm still wondering.  Who could have possibly started/spread that rumor
and why?

   What I tell customers is, "If you are going to plant bird-planted
seedlings, you could get black/red crossed plants."  I test most of my
seedlings and occasionally one yields purple fruit but I can't see how that
might be a problem with most people.

   One other possibility is that cane borer infestations are less likely to
be noticed among reds because of the multitude of canes and could become a
problem in the blacks (blacks typically have fewer canes).

   None of my customers could tell from whom they heard the rumor or why.
Please; would you venture a guess?
