Description

Solanum infundibuliforme (infundibuliforme meaning “funnel shaped”) is a high altitude species, growing natively in dry regions with almost year-round frost exposure, similar to S. acaule.  Small plants, about 4 to 10 inches tall.  Fuzzy leaves and stems.  Stolons reach about two feet.  Tubers small, mostly round, mostly less than an inch in diameter, occasionally reaching about two inches in cultivation.  It is native to the three border region of southern Bolivia, northeast Chile, and northwest Argentina.

Resistances

This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977).  Vega (1995) found that this species is more frost tolerant than domesticated potato.

Glykoalkaloid content

Little information is available about the glycoalkaloid composition of this species.  Petersen (1993) reported that the primary alkaloid is solanidine, which usually indicates that the glycoalkaloids are solanine and chaconine.

Tubers that I have sampled had good flavor but a slightly bitter aftertaste, so this species is probably not safe to eat.

Cultivation

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

Towill (1983) found that seeds of this species stored at 1 to 3 degrees C germinated at 86% after 12 years and 46% after 18 years.

Trapero-Mozos (2018) determined that this species will tolerate a temperature of 40 C after acclimation for a period of time at 25 C.

Breeding

A mutation was discovered in S. infundibuliforme, called topiary.  It is a single recessive gene, tp (Leue 1982), located on chromosome 3 (Wagenvoort 1988), that affects growth habit and tuberization.  According to Den Nijs (1980), the mutation removes apical dominance so that the plant becomes short and bushy.  At the same time, it causes early and extended tuber growth and much shorter stolons.  This can have the effect of overcoming short day photoperiod.
