Description

Solanum andreanum distribution Map note

Solanum andreanum is a species found in Ecuador and Colombia, growing at elevations between about 11,500 and 13,000 feet.  Plants a little more than a foot tall.  Flowers large, purple.

Vega (1995) found that this species is less frost tolerant than domesticated potato.

Cultivation

I have found this species slow to germinate using the standard conditions for S. tuberosum.  The USDA potato genebank has observed that germination of some accessions of this species is inhibited by GA3 (Bamberg 1999).

Breeding

Crosses with S. tuberosum

Watanabe (1991) found that 13.9% of varieties of this species produced 2n pollen (calculated from the results for S. andreanum and S. tuquerrense, which has since been reclassified as S. andreanum), which would be effectively tetraploid and 4EBN.

Crosses with other species

Jackson (1999) found 9-12% 2n pollen for varieties of this species.
