S. demissum is a wild relative of the domesticated potato and is native to Mexico and Guatemala.  Plants are tall and often sprawling and produce very small white tubers.  The tubers probably should not be eaten due to high glycoalkaloid content, but this species doesn’t generally yield enough to bother eating anyway.  Generally, S. demissum is used in breeding programs to introduce wild traits to domesticated potatoes, particularly late blight resistance.  Our wild potatoes are not fully isolated, so while most of the seeds will be purely S. demissum, some may be crossed with other wild or domesticated potatoes.  Any that are crossed may well turn out to be the most interesting of the batch.  S. demissum has an endosperm balance number of 4, so it can be crossed directed to tetraploid domesticated potatoes, although this typically results in pentaploids that must be backcrossed several times to S. tuberosum to produce a regular tetraploid.

25 seeds collected from mixed varieties or 3 tubers.  The tubers may be of more than one variety or all the same.
