'Tango' mandarin is becoming one of the most demanded varieties in the Mediterranean Region. However, no information on the quality of 'Tango' fruit in this citrus area has been reported. In this study, the physico-chemical, nutritional and sensorial quality of 'Tango' mandarins grafted onto Carrizo Citrange and FA5 rootstocks from two locations (Sevilla and Huelva) was evaluated by harvest season. The fruit from Sevilla exhibited lower levels of acids and sugars than those from Huelva, which was associated with a higher sandy soil percentage in the Huelva orchard. In both orchards, the FA5-produced fruit had higher sugars and acids. Flavonoids were affected mainly by location, and the Huelva fruit exhibited the highest levels. The highest vitamin C was for the FA5 fruit. The decreased antioxidant capacity observed throughout the harvest season was related to reduced vitamin C. The sensorial evaluation corroborated changes in the quality parameters.
