This page is a draft, part of our ongoing wild potato project. I’ll probably be adding information to the species pages through 2020 at least, but I’m making them public since they may be useful even incomplete.

Solanum x blanco-galdosii

Common Name(s): Papa de Gentil

Synonyms: none

Series: Piurana

EBN: 2

Ploidy: Diploid

Segregation: Disomic

Self-compatible: Unknown

Cytoplasm Type: W (Hosaka 2014)


S. x blanco-galdosii is a hybrid species, thought to be a cross of S. chomatophilum x S. peloquinianum and has been experimentally recreated by the International Potato Center (Ochoa 2004).  There may be a little more complexity to the background of this species.  Ames (2010) found that S. x blanco-galdosii grouped genetically with S. jalcae in addition to the previously recognized parent varieties.  This is part of a small group of very interesting dryland species from Peru that have very long, thin leaves.

This hybrid might be a useful source of drought resistance genes if it could be crossed to domesticated potatoes.  One of its parents, S. peloquinianum, grows under some of the driest conditions of any wild potato.

This hybrid is found at medium elevations in Peru, generally in cool, dry valleys.
