Rubus arcticus. I’ve seen them in the wild in Denali NP.

One Green World has improved Swedish varieties, but yield is still low. USDA-ARS says that Autumn Britten has Rubus Arcticus ancestry (click on the pedigree tab)

With higher ploidy levels at 7x or above different ploidy levels mix more succesfully. Take boysenberry (6x X 8x) as an example. You can find ploidy levels for just about any variety with enough googling. I’ve memorized a lot of them if you can’t.
