Retrieved UF/IFAS extension page. It calls Minneola fairly cold hardy but ranks it just below sister cultivar Orlando; no temperature, site, or freeze-duration measurement is given.

Full indexed article text reviewed. In the Results/Discussion root-distribution passage, the authors state that Rusk (with trifoliate selections) had most feeder roots near the surface in Orlando tangelo plots; the paper also discusses root depth in relation to scion-tree height. Field context is Astatula fine sand, Florida. This citation supports rootstock/scion context, not Rusk own-root traits; no table measurements are imported.

The review groups Orlando among tangelos produced from Dancy mandarin × Duncan grapefruit breeding. This is a review-level hybrid relationship; it supplies no new Orlando field-trial or fruit measurements.

USDA Circular 181, printed p. 6 (scan 12; plate 2 scan 13), describes the Lake tangelo, CPB 52018-G-26. Hodgson’s 1967 account later confirms that the variety originally named Lake was renamed Orlando. Preserve the 1931 Lake account as historical evidence; trial and maturity reports are not current universal performance claims.

In reply #6 of the Valencia discussion, Mark in Texas shifts to Orlando Tangelo, calling it very much like an orange and reporting that the tree was loaded and its fruit excellent. This is a single grower’s qualitative report; the post gives no crop count, fruit sample count, or growing location.

Page footer identifies Citrus ID Edition 2, October 2011; this is edition metadata, not a verified page publication date, and no page author is shown. This page repeats historical parentage and Lake-to-Orlando naming material attributed to Hodgson (1967), but its distinct Chiefland Budwood Facility (2010) note is explicitly for clone F-57-5. Keep its described closed-pollinated UF campus seedling, plant/fruit, early maturity, cold-hardiness and pollinator statements clone-specific; no evidence links F-57-5 to UCR CRC 3874, no sample denominator/protocol/rootstock, and no temperature measurement. Generic morphology options and taste wording have no intensity scale.

Current page metadata lists Published 2003-03-03 and Updated 2018-04-04; the page says first published September 1993, with no exact first-publication day. Only metadata and abstract were recoverable. Abstract attributes a 1911 Dancy tangerine × Duncan grapefruit cross to W. T. Swingle (USDA), initially named Lake tangelo and later renamed Orlando; cross direction and rename year are unstated. The full article/PDF was inaccessible in finite attempts; do not use bibliography items as retrieved evidence or infer a name-change date.

Summary from transcript: English auto-generated captions run 0:00–3:10 of a 3:12 video, with a 15-second gap from 2:48 to 3:03; the page showed only “5 years ago,” so exact publication date is unknown. First-person report concerns one fruit from the creator’s tree, said harvested the prior day; site, exact date, tree age and rootstock are unknown. Transcript reports repeated 11.7% refractometer readings; video description separately reports a later 12.2% Brix recheck after zeroing the device, on the same fruit. These are repeat/revised readings for one sample, not independent fruit samples or a measure of sugar concentration. Do not treat as a controlled trial.

W. P. Bitters · Journal of Citrus Pathology (digital special topic) · 2021 (digital edition; manuscript circa 1986)
At printed p. 82 (PDF p. 88), Bitters summarizes Moreira et al. (1965), who placed Orlando Tangelo among the “low” rootstock drought-resistance group. The source describes nucellar Bara and Valencia Late orange, Dancy tangerine, and Eureka lemon scions budded on 77 tristeza-tolerant rootstocks under nonirrigated conditions in Brazil. It does not identify the accession or clone of any listed rootstock, provide a variety-specific sample count, or report a measured threshold.

The study reports seven-year effects of ten rootstocks on Orlando tangelo trees in arid southwestern Arizona; Savage is one listed rootstock. The article describes fruit on Orlando trees on Savage as having the highest TSS and total acidity, with small fruit and low per-tree production. These are Orlando scion outcomes on Savage rootstock, not fruit or chemistry measurements of Savage itself.
