Conteúdo:	Citrus is among the most important cultivated species in the world. However, the Northern region of Brazil, despite its available cultivation, still presents incipient production and faces numerous environmental factors that require further study to mitigate the impact of genotype-by-environment interactions. To address this issue, an experiment was set up in the municipality of Capitão Poço, Pará, using a completely randomized block design to evaluate six graft/rootstock combinations with AMMI and GGE Biplot analyses. The variable assessed was total fruit weight (FW), that is the total of fruits produced by the plant, measured in kg, in the 2018, 2019, 2020, and 2021a (first half of the year) and 2021b (second half of the year) harvests. Superior rootstocks were ‘Santa Cruz’ Rangpur lime (C. x limonia Osbeck) (T1) and ‘San Diego’ citrandarin (TSK x TRENG-314) (T10). Although T1 and T10 had low stability in certain years, for ideotype aspect T1 was superior in relation to the other rootstocks and, despite the search for more promising materials, which here were the least stable, it must be accepted that there are risks, as there is no way to predict production in later years. Future research should identify which environmental factors favor fruit productivity and which generate instability in the Capitão Poço region.
