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.

Solanum sogarandinum

Common Name(s):




Ploidy: Diploid



Cytoplasm Type: W (Hosaka 2009)


This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977).  Vega (1995) found that this species is more frost tolerant than domesticated potato.  It is also the source of a dehydrin gene that is used to make transgenic cucumbers more cold resistant.

Glykoalkaloid content

Johns (1986b) found a glycoalkaloid content of 28 mg/100 g for a single accession.  The primary glycoalkaloids were solamarines.
