Solanum polyadenium

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.

Cultivation

The USDA potato genebank has observed that some accessions of this species are dependent upon GA3 for germination (Bamberg 1999).

Crosses with S. tuberosum

Watanabe (1991) found that 6.2% of varieties of this species produced 2n pollen, which would be effectively tetraploid and 4EBN.
