Solanum tuberosum subsp. andigenum 2x

PI 195206 at Genesys

Accession Details

A diploid potato collected near Chiquisaca, Bolivia in 1941.  It was originally classified as S. tarijense (now S. berthaultii) and later changed to S. tuberosum, so presumably it will have some wild traits and might be a wild species hybrid.  GRIN notes Colorado potato beetle, blackleg, Verticillium, flea beetle, and leafhopper resistance.  T type cytoplasm (Hosaka 2003).


High germination.  Uniform seedlings with green stems and broad leaves.  Large plants with foliage similar to S. berthaultii.  White flowers.  Tubers elliptic, oblong, round, compressed.  Whites, blues, and reds, many with blue and white.  White flesh, occasionally with blue vascular ring.  Surprisingly good yield and tuber size.  Mid to very long stolons, but mostly very long.  All long day.  Moderate flowering and berrying.  Tubers not bitter – perhaps just a slight hint of sour aftertaste in some of them.  Texture ranges from all-purpose to very waxy.


This accession would have a lot of promise if not for the nightmarishly long and tangled stolons.  Although it is reported to have T type cytoplasm, the plants appear to be male fertile, which suggests that it may not have the nuclear genes that cause infertility in the presence of T type cytoplasm.

This accession was used as the male parent in tetraploid hybrids with Solanum demissum (Walker 1959).
