The vegetative development, fruit yield and quality of 'Fairchild' mandarin [('Clementine' mandarin (C. clementina Hort. ex. Tan.) x 'Orlando' tangelo (C. paradisi Macf. x C. reticulata Blanco)] was evaluated on 'Rangpur' lime (C. limonia Osbeck), 'Swingle' citrumelo (P. trifoliata Raf. x C. paradisi Macf.), 'Cleopatra' mandarin (C. reshni Hort. ex Tan.) and 'Orlando' tangelo (C. reticulata Blanco x C. paradisi Macf.) rootstocks in an experiment installed in Bebedouro, SP, Brazil in 1997. 'Fairchild' trees budded on 'Swingle' citrumelo were smaller, had higher cumulative yield in 2005 and 2006 seasons, higher yield efficiency (kgm-3), showed lower alternate bearing index. Fruit quality was not affected by the rootstock. 'Swingle' citrumelo was considered an adequate rootstock for 'Fairchild' mandarin.
