Solanum tuberosum subsp. andigenum 2x

PI 195204 at Genesys

Accession Details

A stenotomum type diploid collected in Paucartambo, Peru in 1951.

Observations

TPS. Intermediate germinator, 9+ days.  Moderate germination.  Mostly round to elliptic, a few compressed. Mostly blues, whites, a few reds. A few with moderately deep eyes. A few with pronounced lenticels. Mid to late season. Long stolons, reaching six feet or more. Intermediate dormancy.  White flowers.  Speckled berries.  Low seed set.  Tubers often cracked, probably due to drought stress.  Bitter tubers.

Commentary

In two trials, this accession showed little in the way of domesticated traits, other than one plant that produced red tubers.  The tubers are universally small and the stolons universally very long.  The tubers are bitter.  Feels like a Brevicaule complex potato with perhaps a little bit of domesticated introgression.

Hardigan (2017) reports that this accession has a greater content of wild than domesticated alleles and groups in between stenotomum accessions and and S. candolleanum.

Initial seed increase 0.3g.
