Solanum x edinense (edinense meaning from Edinburgh and specifically the botanic garden there) is a natural hybrid species from central Mexico, generally found in areas of potato cultivation. Thought to be a cross of S. demissum and cultivated S. tuberosum. Plants range from three to six feet tall. Blue flowers. Round berries. Possibly sterile.

Glykoalkaloid content

No information, but intentional crosses between the putative parent species have generally segregated for glycoalkaloid content, with some palatable progeny.





This was one of the first wild potato species used in breeding with the domesticated potato.  The variety Brennragis, a S. x edinense x S. tuberosum hybrid, was released in 1936 (Ross 1966).
