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.

Description

Solanum x doddsii (doddsii, in honor of potato researcher Kenneth S. Dodds) is a hybrid species native to dry valleys in the Bolivian Andes.  Plants reach about two feet tall.  Tubers are round, reaching about an inch in diameter.  Flowers light purple.  Berries small and round.

Vega (1995) found that this species is less frost tolerant than domesticated potato.
