Description

S. berthaultii is a wild relative of the domesticated potato and is native to the southern Andes.  Plants are small and produce very small, white tubers.  While they are edible in very small amounts, this species doesn’t generally yield enough to grow for that purpose.  Instead, S. berthaultii is used in breeding programs to introduce wild traits to domesticated potatoes, particularly resistance to Erwinia spp. and Verticillium and trichomes that repel certain insects, such as aphids.  The commercial variety King Harry, which is reputed to have improved insect resistance, is the result of hybridization between a domesticated potato and S. berthaultii.  Our wild potatoes are not fully isolated, so while most of the seeds will be purely S. berthaultii, 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. berthaultii has an endosperm balance number of 2, so will generally need to be crossed to diploid potatoes 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.
