    Revisiting a citrus rootstock trial planted in 1997 at the Loxton Research Centre has revealed issues which were not apparent in the early life of the trees. In particular there is strong evidence of incompatibility of Navelina orange scion on three rootstocks.Tree deaths within the patch since 2006 suggest incompatibility of Navelina 7.5 with C35 citrange, and F80-5 and F80-7 citrumelo (same parentage as Swingle citrumelo) rootstocks. All 24 scion/rootstock combinations performed adequately as young trees (up to 10 years), but since then 20 of the 27 trees of Navelina 7.5 on these three rootstocks (randomly replicated throughout the trial) have died, with no deaths in any other scion/rootstock combination.It is recommended that Navelina 7.5, and closely related varieties Navelina 315, M7 and FJ Navel should not be budded to C35 citrange, or on F80-5 or F80-7 citrumelo.
