Paul, I just read your note about the disease resistance of Cannikin being so good. You may want to cross R. moyesii pollen onto it next season - this cross resulted in 24 seeds from two hips this season.
But did they GERMINATE?! I generated literally hundreds (perhaps as many as 1000) seeds from Midnight Blue X moyesii in 2011, but not a single one germinated. Just sayin'
I'm more inclined to cross Cannikin with other tetraploids of known fertility, like Bayse's Blueberry, for example. Whats that you say??....pink, pink and more PINK?! *laughs* yes, well......you have to make compromises in the search for genuine health, I think ;-)
