Introduction – The tangor cv. Ortanique presents positive characteristics for the fresh fruit export market, however little is known about this genotype in Brazil. In this study, we evaluated the ideal harvest time on two rootstocks, the fruit juice carotenoid content and possible postharvest storage of 'Ortanique' fruit. Materials and methods – The cultivar was grafted on 'Swingle' citrumelo and Poncirus trifoliata and was evaluated to the following variables: plant height, diameter and canopy volume, fruit physical and chemical quality [mass, soluble solids (SS), titratable acidity (TA) and the ratio (SS/TA)], production and productive efficiency in each graft combination. Carotenoids content of 'Ortanique' fruit juice grafted on 'Swingle' was qualified by HPLC. The optimal storage time of 'Ortanique' (with or without wax, stored at 10 °C or at room temperature) were determined for six weeks storage. Results and discussion – The rootstock 'Swingle' provided great growth and plant production of 'Ortanique' plants while Poncirus trifoliata delayed fruit maturation. The 'Ortanique' fruit juice contained high levels of ß-cryptoxanthin and cis-violaxanthin and the fruit could be stored at 10 °C for six weeks without losing quality. Conclusion – The 'Ortanique' tangor has productive potential for commercial cultivation in Brazil, being late-maturing, its fruit high in carotenoid content and possibly well adapted to long storage for export.
