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 multiinterruptum

Common Name(s):

Synonyms: S. chrysoflorum, S. moniliforme


EBN: 2

Ploidy: Diploid

Segregation: Disomic


Cytoplasm Type:



Condition Level of Resistance Source

Glykoalkaloid content

Johns (1990) found levels of 50 and 68mg/100g for two accessions tested.  The primary glycoalkaloids were solanine and chaconine.  They also found a level of 42mg/100g but that accession was later reclassified.


The USDA potato genebank has observed that germination of some accessions of this species is inhibited by GA3 (Bamberg 1999).
