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.

Glykoalkaloid content

Johns (1986b,1990) found glycoalkaloid levels ranging from 28 to 70mg/100g for five accessions of S. raphanifolium.  The primary glycoalkaloids were solanine and chaconine. 


I have found this species slow and difficult to germinate.  It may require different conditions than the standard for S. tuberosum.
