Solanum okadae (okadae in honor of Argentinian potato expert K.A. Okada) is primarily a western Bolivian species, ranging south into Argentina, growing in moist mid-elevation habitats.  Plants about a foot tall.  Stolons two feet long or more.  Tubers round to ovoid, reaching about an inch in diameter.  Flowers white.  Berries round and a little more than 1/2 inch in diameter.

Subramanian (2017) found that at least some accessions of this species have unusually high dry matter content.

EBN of this species has not yet been determined.

Resistances

Ochoa (1990) notes that this species is unusually vulnerable to late blight.  Vega (1995) found that this species is less frost tolerant than domesticated potato.

Crosses with other species

Jackson (1999) found 4-10% 2n pollen for varieties of this species and Camadro (2008) found 0 to 5% 2n pollen and 0 to 3% 4n pollen.
