Solanum minutifoliolum


Solanum minutifoliolum distribution Map note

Solanum minutifoliolum is a species of small distribution in central Ecuador, growing at elevations of 8,200 to 9,800 feet (2500 to 3000 m).  Plants grow to about three feet tall.  Flowers stellate and blue to purple.  The specific epithet, minutifoliolum, refers to the small leaflets of this species.  Very little has been written about this species.


Chacon (2007) noted that this species was difficult to infect with late blight, but that it demonstrated no resistance once infection was successful.

Seedling of the wild potato species Solanum minutifoliolum
Solanum minutifoliolum seedling


I have found seeds of this species very difficult to germinate using the standard conditions for S. tuberosum.

Accessions Evaluated

The following accessions were examined to prepare this profile.  I have evaluated 1/1 accessions currently available from the US potato genebank.

PI 583298

The first attempt to germinate this accession failed.  On the second attempt, I placed the pot outside after attempting to germinate for two months and finally got a single seedling after three months outdoors, so a total of five months to the first germination.
