Description

Solanum venturii distribution Map note

Solanum venturii (venturii in honor of Argentinian botanist Santiago Venturi) is a wild potato species native to northern Argentina.  This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977).  Vega (1995) found that this species is less frost tolerant than domesticated potato.

Glykoalkaloid content

Van Gelder (1988) found TGA levels ranging from 138 to 250 mg  / 100 g for this species.  These levels are far in excess of the safety limit of 20 mg / 100 g, so this species appears to have little potential as an edible.
