This page is a draft, part of our ongoing wild potato project. I’ll probably be adding information to the species pages through 2020 at least, but I’m making them public since they may be useful even incomplete.

Crosses with other species

Watanabe (1991) found that 9.1% of varieties of this species produced 2n pollen and Jackson (1999) found 6-21%, which would be effectively octaploid and probably 4EBN.
