Solanum x sambucinum

Description

blankSolanum x sambucinum is a nothospecies (a naturally occurring hybrid) from Michoacan, Mexico. Thought to be a cross of S. ehrenbergii and S. pinnatisectum. Plants roughly one to two feet tall. White flowers. Round berries.

Jarvis (2008) predicts that this species will lose 95% of its present range by 2055 due to climate change, most likely entailing a critical loss of genetic diversity.

Hale (2008) found that S. x sambucinum had high antioxidant activity.

Cultivation

Accessions Evaluated

The following accessions were examined to prepare this profile.  I have evaluated 1/1 accessions currently available from the US potato genebank.

PI 595478

Collected in Querétaro Mexico in 1993.  This is the only accession currently held by the US potato genebank, so there is no possibility of seed production, although it does seem to cross pretty easily with other 1EBN diploids.

Crosses with other species

Matsubayashi (1977) examined chromosome pairing in hybrids and determined that S. x sambucinum and S. jamesii were highly compatible and likely closely related.
