There's a Blueberry unique to the State of Maine (where I reside)….MOB, Maine's Own Blueberry or Maine Original Blueberry. Nobody, and I do mean, NOBODY has the right to claim to be the "inventor" of the strain Blueberry. MOST of the B-I-G Seed Banks in Europe have large seed operations in Spain, churning out millions of seeds annually. Manipulating the time in order to produce seeds can ALSO contribute to the weakening of strains. Additionally, Do si Dos was a breeding of TWO SEPARATE Strains, right? What if I took the SAME two parent strains, combined them to produce seeds, wouldn't the resulting seeds be Do si Dos? If I then called them Do see Dos, am I wrong? If you don't know the innerworkings of a Seed Bank(s), I wouldn't generalize. Unless seeds are carried out to f7 or f8, certain traits can't be guaranteed. My humble observations in this regard. Enjoy a Happy Easter and above all, be safe.
