Summary from transcript: Only one older Morton plant survived a prior harsh season while smaller grafts did not; its fruit was described as large, seedless, and an orange–grapefruit mix (57:19–58:08).

Near-full auto-generated transcript reviewed with the matching scorecard archive. This citation supports only the presenter’s stated, unscored comparisons; it does not identify a current tree, prove a pedigree, or establish measured hardiness.

Three-page English archive topic “Ichangquat.” IlyaC (France, about 40 km south of Paris) reported on 11 October 2011 that Citrange Morton fruit remained green while his Ichangquat fruit was beginning to yellow (page 3, post #48034). This is a visual, local color comparison, not a validated measure of internal maturity.

Individual scorecard image for Morton Citrange. The printed preference ratings are sweetness 7/10, sourness 3.5/10 and bitterness 8/10; the linked fruit reference preserves these original ratings alongside catalog numeric scores. Sweetness is stored as printed; sourness and bitterness use 10 minus the printed score. Any Brix or pH printed on the card is a separate reading, not derived from ratings. Sample method and harvest date are not stated unless noted in the reference.

Collection/acquisition report only. Gregn’s post #86 lists Morton Citrange among a new imported batch; its timestamp is 7 August 2007, while the post calls the list an “October update,” so preserve that chronology ambiguity. Post #90 (29 October 2007) lists Morton without an asterisk, which the author uses for in-ground plants. The stated −5 to −12 °C range applies to “most” of the collection’s hardy varieties, not specifically Morton; the unnamed winter casualty is not identified as Morton. No Morton fruiting or cold-outcome report is given.

The page quotes an older Morton fruit description attributed to a book (p. 278) and recounts an early cross between sweet orange and trifoliate orange producing named citrange seedlings. Its 1896–1899 date is the blogger’s inference from cited pollination and first-fruiting information, not a contemporary dated cross record. The page separately states an unlocated, unattributed 5°F hardiness figure; it is not a verified cultivar limit. The quoted fruit account lacks accession, site, sample count, harvest date, and tasting method.

Summary from transcript: 31:46 video; English auto-generated captions cover 0:01–31:42; no exact publication date verified. The presenters say the sampled Morton was the last fruit on Stan McKenzie’s tree, compared with one Rusk fruit; both were picked in early November in the Carolinas and may have been slightly early (0:13–0:24; 2:04–2:49). The Morton fruit weighed 247 g, had no seeds or nearly none, and was described as sour with strong orange flavor, little bitterness and some sweetness (3:20–3:54; 6:46–8:55; 10:43–15:45). The speaker reports a refractometer reading of 11.5 °Brix and a pH test-strip reading around 3 for this fruit (16:45–17:24); these are reports for this sample, not variety constants. Tentative parentage and estimated citrange cold claims are excluded from catalog conclusions.

Summary from transcript: 5:11 video; English auto-generated captions cover 0:00–5:09; no exact publication date verified. The grower reports ripening his first mature Morton fruit in a heated greenhouse; the speaker says Morton is a Zone 8 plant (1:08–1:38). He describes one fruit with some green flesh and possible immaturity (1:58–3:04), reports a carrot-like rind scent and very acidic/tart juice (1:40–1:55; 3:38–4:04), and says juice after dilution/sweetening had a Tang-like taste (4:04–4:39). This is one possibly underripe fruit, with no Brix, pH or weight. He reports hand-pollinating a flower with Meyer lemon and wonders whether seeds may produce an off-type; this is not verified parentage.

User-provided excerpt attributed to Josue’s four-taster group report, with fruit obtained from Stan McKenzie the prior week in South Carolina zone 8a. This entry records only the Morton portion: it was described as having low bitterness and noticeable Poncirus flavor. The underlying thread has not been independently retrieved; exact accession, fruit count, maturity, and method are not stated. Four tasters is the number of tasters, not a stated fruit sample count.

Hall et al. evaluated citrus-relative seedling populations for Asian citrus psyllid (ACP) colonization. Table 4 reports CRC 1463 ‘Morton’ in a March 2014 free-choice test; Table 1’s CRC 2748 Morton entry is a different accession. These data concern experimental ACP oviposition, not orchard-level HLB control.

The Archive.org item identifies this as a 1909 reissue of Webber’s 1905 account, reprinted with slight changes. Its “Name and Origin” section says Morton No. 771 was one of 40 seedlings from a Trifoliate orange pollinated with sweet orange by Walter T. Swingle at G. H. Norton’s grove in Eustis, Florida; 11 showed intermediate foliage indicating hybrids. This is the historical account in the reprint, not accession-specific molecular parentage.

Webber's 1907 Colman description explicitly compares Colman fruit and pulp color with Morton. This is a historical relational comparison, not a Morton-specific color measurement or accession-specific sample report.

Printed p. 7 places Morton among eleven named citranges from a single Poncirus trifoliata fruit pollinated with Ruby sweet-orange pollen in the 1897 crossing series. The passage was checked through the archived full-text transcription because the official PDF was inaccessible; official article metadata confirms authors and citation year.
