The goal of this study was to evaluate vegetative growth, yield performance, and fruit quality of Navelina sweet orange trees grafted on five different rootstocks in Northern Parana state, Brazil. The experimental design was completely randomized blocks, with six replications, two plants per plot, and five treatments: Rangpur lime; Cleopatra mandarin, Sunki mandarin; Swingle citrumelo; and Fepagro C-13 citrange. Tree vegetative growth, yield performance, and fruit physical-chemical characteristics were analyzed. Sunki mandarin provided the largest canopy volume for Navelina sweet orange trees, whereas Swingle citrumelo, Fepagro C-13 citrange, and Rangpur lime provided a smaller volume for tree canopy. Compared to Rangpur lime, Swingle citrumelo provided higher accumulated yield and production efficiency for Navelina sweet orange trees. All rootstocks induced good physical and chemical quality to Navelina sweet orange fruits.
