Solanum multiinterruptum


Solanum multiinterruptum distribution Map note

Solanum multiinterruptum is a wild potato species from northern Peru.  Plants to about three and a half feet tall.  Flowers blue/purple or white.  Berries small and ovoid.

The specific epithet, multiinterruptum, means “multiply interrupted,” presumably referring to the large number of small leaflets.  While there is no completely standardized pronunciation for scientific names, the most common way to pronounce this species is probably so-LAY-num mul-tee-in-ter-RUP-tum.


Vega (1995) found that this species is about as frost tolerant as domesticated potato.

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).
