Citation
Joint FAO/IAEA Division. Mutation Breeding Newsletter 31 — supplied Hoya table excerpt. March 1988. pp. 24–25 (supplied original PDF p.2).
The reported Hoya entries
The supplied excerpt from Mutation Breeding Newsletter 31 lists Compacta, Compacta Regalis, Mauna Loa and Rubra in a table of cultivars and reported mutation treatments. The Hoya entries give 1980(?) and X- or gamma rays, 50 Gy, with rooted cuttings(?). The printed question marks are part of the evidence.
The Compacta Regalis row describes white-edged curved leaves. The excerpt contains the cover and a two-page table spread, not the full issue, its introduction or a primary laboratory record.
Interpretation limits
This is a historical register-style report. It does not establish that irradiation originally created the named cultivars, identify a treated accession or resolve the chronology against the earlier patents. The 2025 Cobia nursery interview gives a different account of irradiation and natural sports. Neither account is treated as a controlled experiment or proof of a genetic mechanism. The table image is retained privately and is not reproduced here.
Evidence scope and limits
Original and separate extraction filed; historical source statements and explicit uncertainties retained.
