An increasing interest in the antioxidant capacity of vegetables has led to the development of novel potato clones. However, little is known about the effect of production environment on antioxidant levels in potato. The main purpose of this study was to determine the effect of genotype  and  environment  on  antioxidant  activity  of  potato  tubers.  In  this  study,  three replications of 22 high antioxidant breeding clones (developed by C. Brown) and three controls (Yukon Gold, Russet Burbank, and Snowden) were planted in four environments: organic (no irrigation), organic (irrigation), conventional (central sands), and conventional (northern Wisconsin). Samples of freshly harvested tubers were diced into 1 cm cubes (including the pel), frozen in liquid nitrogen, and stored at -80°C until analysis. In addition, tuber samples were stored  at  5.6°C  for  four months  and  processed  similarly.  The  TEAC  (Trolox  equivalent antioxidant capacity) assay for evaluating antioxidant levels in human tissue was adapted for tuber tissue. Antioxidant activity was determined for all clones at all sites for both fresh and stored tubers. Antioxidant activity of fresh tubers at all locations was higher in 2006 than in 2005. Cooler late-season temperatures in 2006 may have been responsible for the increased levels of antioxidants.   Stored tubers had higher levels of antioxidant activity than fresh tubers, with a larger storage effect in 2005, when antioxidant levels in fresh tubers were lower. There was no consistent effect of production system (organic versus conventional) on antioxidant activity in tubers.  For the specialty potato clones we evaluated, antioxidant levels were generally highest in potatoes grown in high-yielding production environments, and they increased during storage. Therefore, potatoes with high nutritional value, in terms of antioxidant activity, can be produced using conventional production and storage systems.
