Solanum commersonii is a species of wild potato native to South America. It belongs to the genus Solanum in the family Solanaceae. This species is of particular interest due to its potential use in potato breeding programs.

Description

Solanum commersonii is a perennial herbaceous plant that typically grows to a height of 30-60 cm. The plant has compound leaves with 7-9 leaflets. The flowers are purple and the fruit is a small, green berry.

Distribution and Habitat

Solanum commersonii is found in the wild in Argentina, Brazil, Paraguay, and Uruguay. It typically grows in grasslands, savannas, and along the edges of forests.

Taxonomy

Solanum commersonii was first described by the French botanist Michel Félix Dunal in 1816. It is closely related to the cultivated potato, Solanum tuberosum, and is part of the Solanum sect. Petota.

Uses

The primary interest in Solanum commersonii lies in its potential for potato breeding. It possesses several traits that are valuable for improving cultivated potatoes, such as resistance to frost, diseases, and pests.

Conservation Status

The conservation status of Solanum commersonii has not been extensively studied. However, like many wild relatives of cultivated plants, it may be at risk due to habitat loss and climate change.

Research

Ongoing research is focused on understanding the genetic diversity of Solanum commersonii and its potential for use in agriculture. Studies are also being conducted to explore its ecology and evolution.
