Performance of 'Jaffa' sweet orange on different rootstocks for orchards in the Brazilian Northeast

Abstract

Abstract: The objective of this work was to evaluate the effect of nine rootstocks on 'Jaffa' sweet orange (Citrus sinensis) for its vegetative, productive, and qualitative traits, and for its susceptibility to three pest mites (Eutetranychus banksi, Tetranychus mexicanus and Phyllocoptruta oleivora). The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo Santa Cruz' lime, 'San Diego' citrandarin, and the hybrids HTR-051 and LVK x LCR-010 conferred lower-cumulated yields to 'Jaffa'. The rootstocks did not influence the population levels of the evaluated mites. 'Sunki Tropical' mandarin, 'Cravo Santa Cruz' lime and 'Rugoso Vermelho' lemon stand up as excellent rootstock options for 'Jaffa' sweet orange in the Northeastern Brazil.
