Tostado correctly points out that the pentatonic MAJOR scale is often associated with country music while pentatonic minor (sometimes the hexatonic minor with the added flattened fifth) is a blues scale. I also agree that a lot of the well known Southern rock leads visit the pentatonic major scale at some point.
To be fair, rock n roll music was originally characterized by many as "the bastard child of country and blues" because the highest profile players (see Chuck Berry) moved fluidly from the pentatonic minor scale to the pentatonic major and back. So, what some may hear as country influences, others may hear as '50s rock n roll.
TO MY EAR (tho I'm not about to argue with anyone who disagrees) one of the characteristics that makes Southern rock a distinctive genre is that it seemed to re-introduce the pentatonic major BACK into hard rock, which - over the course of the '60's had seemed to generally migrate further and further towards blues style leads at the expense of country influences.
So, I personally hear a lot of country in the Southern rock genre as a whole. YMMV.
