Description

S. acaule is a wild relative of the domesticated potato and is widespread in the Andes.  Plants are small and low growing and produce very small, white tubers.  Like most wild potato species, S. acaule is not really edible.  (It is probably safe to eat very small amounts, but it has higher levels of glykoalkaloids than domesticated potatoes.)  Instead, S. acaule is used in breeding programs to introduce wild traits, particularly frost resistance, to domesticated potatoes.  Our wild potatoes are not fully isolated, so while most of the seeds will be purely S. acaule, some may be crossed with other wild or domesticated potatoes.  (S. acaule almost always self-pollinates, so crosses of this species are particularly rare.)  S. acaule has an endosperm balance number of 2 and so must first be crossed to diploid potatoes in order to introduce traits to tetraploids.  Seeds of S. acaule often need to be treated with gibberellic acid (GA3) to obtain good germination.

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