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.

Solanum stoloniferum

Common Name(s):

Synonyms: S. ajuscoense, S. antopoviczii, S. boreale, S. candelarianum, S. fendleri, S. longipedicellatum, S. malinchense, S. neoantopoviczii, S. papita, S. polytrichon, S. tlaxcalense, S. tuberosum var. boreale, S. wightianum

Series: Longipedicellata

EBN: 2

Ploidy: Tetraploid

Self-compatible: Yes

Cytoplasm Type: D, W (Hosaka 2014)

Description

This species can survive frosts down to 27 degrees F (-3 C) (Li 1977).

Although S. stoloniferum is tetraploid, it has disomic chromosome segregation, which probably explains why it is self-compatible.

This species is an allotetraploid, with two constituent genomes.  Pendinen (2008) determined that the two genomes are derived from S. verrucosum and S. cardiophyllym, S. ehrenbergii, or S. jamesii.

Crosses with other species

Watanabe (1991) found that 8.7% of varieties of this species produced 2n pollen (calculated from the totals for S. stoloniferum and S. fendleri, S. papita, and S. polytrichon, which have been reclassified as S. stoloniferum) which would be effectively octaploid and 4EBN. Jackson (1999) found 0-29%.

Glykoalkaloid content

Johns (1990) found glycoalkaloid levels of 64 and 69mg/100g for two accessions of this species (as S. fendleri). The primary glycoalkaloids were solanine and chaconine.
