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

(kurtzianum, in honor of German botanist Fritz Kurtz)

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.

Cultivation

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

Bamberg (1995) found that at least some accessions of S. kurtzianum are able to produce a significant amount of viable pollen even when temperatures exceed 100 degrees F for several hours during the day.  Flowering was reduced under these conditions.
