Description

Solanum sogarandinum (sogarandinum meaning from Sogaranda, Peru) is a wild potato species native to central to northern Peru.  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.  This is close enough to the safety zone that it is pretty likely that edible varieties can be selected.
