Solanum tuberosum subsp.andigena

after Rodríguez andigena displays dormancy

The origin of the cultivated potato was described as the result of successive hybridizations between diploid members of the S. brevicaule complex, accompanied by chromosomal duplication processes that gave rise to tetraploid forms.

Selected from the wild species S. bukasovii, S. canasense and S. multidissectum, S. stenotomum is considered the oldest cultivated diploid potato species, which would have given rise to the Andigena type potatoes. Later, these would have been modified by sexual polyploidization and intervarietal or introgressive hybridization, and then widely dispersed. At present they are known as S. andigena or Andigena group. This group is characterized by being tetraploid and highly polymorphic, and from the genetic point of view is considered as the most closely related to S. tuberosum subsp. tuberosum or S. tuberosum Chilotanum Group, and as its possible ancestor. These tubers are planted in the coastal regions of Chile, from where they would have spread to the rest of the world, collectively known as Solanum tuberosum
