L. de  aRootstock-related improved performance of 'Pera' sweet orange under rainfed conditions of Northeast Brazil.h[electronic resource]  c2020  aCitrus orchards in the coastal tablelands of Northeast Brazil are almost exclusively composed of?Pera CNPMF D-6?sweet orange, henceforth?Pera?, grafted on?Rangpur?lime. Therefore, assessing new rootstocks for?Pera?inthis region is pivotal for diversification purposes, potentially leading to increased competitiveness, yield andfruit quality. In this study, vegetative growth, productive performance, pest attack and fruit quality of?Pera?,grafted onfive rootstocks, were assessed over 10 years in Northeast Brazil. The trifoliate hybrid HTR-051conferred the highest yield efficiency to?Pera?, while?Red Rough?lemon and LVK x LCR - 010 induced precocity,with yields exceeding 9400 kg ha?1in thefirst harvest, as well as the highest cumulative yields.?Red Rough?lemon, LVK x LCR - 010 and HTR-051 were notable for imparting high weight and total soluble solids to?Pera?fruit. Regarding pests, the highest densities of citrus rust mitePhyllocoptruta oleivorawere found on the fruit of?Pera?grafted on LVK x LCR - 010, despite low densities of this arthropod over the sampling period. Altogether,our results highlight?Red Rough?lemon and LVK x LCR?010 as superior rootstocks for excelling in productiveperformance and fruit quality. In addition, HTR-051 manifests as an excellent option for high-density orchardsbecause it induces dwarfism and high production efficienc  aLaranja Pêra  aPorta Enxerto  aCrescimento vegetativo  aTolerância à seca1 aTEODORO, A.
