Russian Blue is grown as a separate variety but it does seem to be near or identical to many other clones synonymously named.
The cross Adirondack Red was made in 1994. The female was N40-2 (Chieftain x Black Russian) which may be the same as Russian Blue. Russian Blue and/or Black Russian may be clonal selections of All Blue...I just don't know. When I ask the other breeders...they don't know either...
