Strawberries (San Andreas, Sea Scape, Chandler, Festival, Albion and Radiance) were cultivated in high tunnel and open field in Lubbock, Texas. Matured fruits were harvested and analyzed for their antioxidant potential, total phenolics, sugars and titratable acidity to evaluate the overall quality of the fruit. Among the six cultivars harvested in both high tunnel and open field, Chandler, Festival, and San Andreas had significantly higher phenolic content ranging 2136.45 to 2230.47 �g/g catechin equivalents, while Chandler, Sea Scape, San Andreas and Festival cultivars had significantly higher radical scavenging activity ranging 1645.87 to 1974.42 �g/g ascorbic acid equivalents. Fruits harvested from high tunnel cultivation had higher levels of sucrose and fructose, while maintaining the glucose levels, titratable acidity, phenolic content and radical scavenging activity as compared to open field grown strawberries. These results indicate that high tunnel cultivation could be a viable strategy for production of strawberries with better quality and phytonutrients.
