The Potato Landraces of the Canary Islands: Their history, diversity and origin of the potato in Europe

With this title, on October 18 at 09:00 a.m. (EST), the World Potato Congress will offer its fourth webinar in English and first in Spanish (which will be held at 10:00 a.m. the same day).

The two speakers, André Devaux y Domingo Ríos will participate in both presentations.


Today in the Canary Islands (Spain), more than 50 potato varieties are grown. Their unique characteristics have been kept and cultivated for 450 years since the conquistadors introduced them from America.

The Canary Islands are comparable to a natural laboratory for the products from America in the 16th century. This is the case with potatoes, which have been planted over the years, allowing them to evolve into great diversity.

The webinar will provide the following:

  • description of the origin of the potato
  • history of ancient potatoes in the Canary Islands since their arrival from the Andean region
  • analysis of the characteristics of these varieties (cultivated and conserved) and their genetic diversity, integrating morphological, agronomic and molecular data.

It should be noted that there is a high probability that there were potato cultivars in the Canary Islands, introduced in parallel from the Andes and Chiloé in southern Chile. These data contribute to studying the first potatoes that entered Europe and their subsequent evolution.
