S. chacoense is a wild relative of the domesticated potato and is native to Argentina, Bolivia, Paraguay, and Brazil.  Plants are tall and often sprawling and produce small, white, tan, or blue skinned tubers.  While they are edible in very small amounts, this species doesn’t generally yield enough to grow for that purpose.  We do have a few varieties that produce two inch tubers, so this species might hold some promise for breeding even without crossing to domesticated potatoes.  Generally, S. chacoense is used in breeding programs to introduce wild traits to domesticated potatoes, particularly disease resistance and heat tolerance.  Our wild potatoes are not fully isolated, so while most of the seeds will be purely S. chacoense, 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. chacoense is diploid and has an endosperm balance number of 2, so generally must be crossed to diploids in order to introduce traits to tetraploids.

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