This work evaluated for 14 years, in Paranavaí, PR, Brazil, the performance of 'Folha Murcha' orange trees budded on the following rootstocks: 'Rangpur' lime (Citrus limonia), 'African' rough lemon (Citrus jambhiri), 'Volkamer' lemon (Citrus volkameriana), 'C-13' citrange (Citrus sinensis × Poncirus trifoliata), trifoliate orange (Poncirus trifoliata), 'Sunki' mandarin (Citrus sunki) and 'Cleopatra' mandarin (Citrus reshni). The experimental design was in blocks, with seven treatments (rootstocks), four replications, three trees per plot of each rootstock. The tree canopy volumes on 'Cleopatra' mandarin and 'African' rough lemon were significantly larger. Trees on 'Rangpur' lime showed the smallest difference between the rootstock and scion trunk diameters. Cumulative yield was higher in trees on 'African' rough lemon and 'Cleopatra' mandarin, and smaller on trifoliate orange. Alternate bearing was not marked in trees of the studied rootstocks. Total soluble solids content was significantly higher in fruits obtained from trees budded on trifoliate orange, and the lowest value occurred on 'African' rough lemon. The juice fruits quality was within the acceptable standards for orange varieties. The 'Cleopatra' mandarin and the 'African' rough lemon are promising as rootstocks for 'Folha Murcha' orange, under the conditions of the evaluated site.
