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 stenophyllidium



EBN: 1

Ploidy: Diploid



Cytoplasm Type:


This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977).

Condition Level of Resistance Source

Bamberg (2017) found a 56% increase in seed set in this species with supplemental applications of liquid fertilizer at four and seven weeks after potting.

Crosses with other species

Watanabe (1991) found that 25% (although only 2 plants) of varieties of this species (as S. brachistotrichum) produced 2n pollen and Jackson (1999) found 7-13%, which would be effectively tetraploid and 2EBN.
