• Solanum tuberosum Group Phureja is a cultivar-group of diploid potato plants originating from the Andes valley in South America. (wikipedia.org)
  • The group differs from other potato cultivar-groups by the absence of dormant tubers. (wikipedia.org)
  • The criteria used to distinguish potato cultivar-groups include non-morphological traits such as frost tolerance, tuber dormancy, daylength adaptation, and ploidy level. (wikipedia.org)
  • While the 20th century saw significant controversy over the species status of S. andigenum and S. tuberosum, and which gave rise to modern potato cultivars, different classifications until 2002 typically agreed with treating S. phureja as a separate species. (wikipedia.org)

  • An exception was K. S. Dodds and G. J. Paxman, who in 1962 suggested it be included as one of five cultivar-groups of S. tuberosum, Group Phureja, based this on a number of factors, particularly poor morphological separation of cultivated diploid species. (wikipedia.org)
  • A 2002 reclassification by Huaman and Spooner found little phenetic support for the then-mainstream treatment of S. phureja as a species. (wikipedia.org)
