The Vero Beach Marsh trial Table 1 lists UFR-10 selection 7R1T68 with source-transcribed parentage Tahiti sweet orange x FDT. It does not state cross direction. The separate Indiantown whole-bed trial identifies FDT as Flying Dragon trifoliate orange (Table 1, p. 6; legend, p. 11); this resolves the code at the common-name level but does not specify the exact accession. Both source-reported components retain unknown roles.

Revision: Resolve the Vero Beach table abbreviation FDT using the separate UF/IFAS source's explicit expansion, linking to the canonical Flying Dragon cultivar while retaining the original trial citation and unknown cross roles; do not infer a specific accession or UFR-10 performance from the second trial.
