This page is specifically for UCR accession CRC 3830 / PI 539554 / VI 362, distinct from CRC 3811 / PI 539550. Its Source section records budwood received from USDCS, Indio, California, via CCPP, in 1975; its Parentage/origins section says parents unknown. A 1988 EMN note says CRC 3830 appears identical to CRC 3811; this is a reported comparison, not proof that the accession records are interchangeable. The page also reproduces a 1967 historical description and lists December–February ripening at Riverside.

HS1500, DOI 10.32473/EDIS-HS1500-2025. The PDF states first published November 2025; exact day not given. Retrieved the page and full eight-page PDF, with every page inspected. The Moro cultivar description on p. 4 is explicitly attributed to Hodgson, The Citrus Industry (1967); it is a historical cultivar description, not a new sample or accession-specific measurement. Broad pigment, climate, cold and rootstock discussion on pp. 2–3 and 6 is scoped to blood oranges generally or to cited studies; it is not a measured Moro hardiness or compatibility record.

Thread opened March 4, 2017; relevant Moro replies include mrsg47 (#2), hoosierquilt / Patty S. (#3 and #5), and Lids (#19; Feb. 8, 2024, first reported crop), followed by a reply from mrsg47 (#20). Reports include subjective and differing comparisons of Moro sweetness/tartness, color and flavor; they are informal grower impressions, not calibrated sensory measurements. A reported first harvest is not accompanied by location, rootstock, sample count, maturity method or measured traits.

Summary from transcript: Video duration 3:28. The English auto-generated caption export spans 0:06–3:21, omitting the first six seconds and final seven seconds; no publication date was verified. Captions visibly mistranscribe names and words. This source is cited for the presenter’s subjective Moro fruit comparison at 2:47–3:00 and rough size comparison with Raspberry Tangor at 2:09–2:32. No dimensions, weights, or numeric fruit measurements are given. The video introduces Raspberry fruit and compares a Moro sample, but sample count is not established. Relative sweet/tart language does not establish a Moro intensity category. The presenter also calls Moro one parent of Raspberry Tangor; this citation’s Moro evidence is limited to Moro fruit comparison.

Summary from transcript: 15:58 video; English auto-generated captions cover 0:00–15:56; page displays “3 years ago” without an exact publication date. The presenter compares four store-bought fruits. The Moro fruit is smaller than the Sanguinelli sample, with size said to vary (1:10–1:22); it has dark red exterior pigmentation (2:14–2:23). In this comparison the Moro has mostly berry flavor with little typical orange flavor (8:01–8:13), and is ranked first for distinctiveness among these particular fruits (12:24–13:25). The speaker says this Moro is lower in sweetness than the others (13:58–14:18), without assigning an intensity score. This is a fruit-specific comparison; the speaker notes fruit variation with growing conditions (8:33–8:55) and cautions these are particular fruits (12:04–12:21).

Summary from transcript: 5:12 video; English auto-generated captions span 0:00–5:12; page displays “4 years ago” without an exact publication date. The presenter describes fruit from their Moro tree, picked that day (0:27–0:48). Fruit is medium-sized (1:03–1:13), with rind blush darkening as it matures (0:41–0:59); the cut fruit’s internal color is uneven, with lighter orange toward the top and darker color toward the bottom (1:25–2:26). The sampled piece has visible juice and few seeds in the cut fruit (1:25–2:32), requires some effort to peel but is not described as very difficult (2:34–3:07). The presenter describes mild sweetness and raspberry-like berry notes (3:24–4:08), and says the juice is not overly sweet with berry notes (4:21–5:00). Subjective single-grower tasting, not a calibrated cultivar-wide measurement.

Summary from transcript: 9:30 video; English auto-generated captions cover 0:00–9:30; the page displays “6 years ago” without an exact publication date. The narration opens “Tuesday, March 10”; later it names the 2019 and 2020 winters, but the publication date is unverified. The presenter’s grafted Moro from McKenzie Farms has been grown in a container on the southeastern North Carolina coast (zone 8a); acquired summer 2018 and had experienced two winters by the narration (0:53–1:09). He says he carries it to the garage when the forecast is 32°F or lower because his location can be 5–6°F colder than forecast, and usually keeps it by a house area that avoids frost (1:23–1:40; 2:24–2:36). He reports defoliation during two warm indoor stays (1:43–2:19). For one first harvest fruit, the speaker estimated 10–12 oz before weighing; the spoken scale reading is 10.85 oz (4:56–5:16). He describes streaked red/purple interior color (5:52–6:24), sweet and very tart fruit, less sweet and more acidic than store Moro (6:36–7:02), and pronounced raspberry-like flavor notes in parts of the fruit (7:22–8:30). These are an individual container-tree and fruit report, not a universal hardiness threshold or calibrated sensory measurement.

Summary from transcript: 2:57 video; English auto-generated captions cover 0:00–2:55; page displays “4 years ago” without an exact publication date. The presenter’s small grafted container-grown Moro tree from McKenzie Farms is in its third full season (0:17–0:35). He reports a harvest of 11 lb / 5 kg at once, after picking about a dozen more fruit periodically during the preceding winter months (1:37–1:55). This tree’s fruit had dark coloring, which the speaker associates with chilly nights in the 40s (2:00–2:14). He calls this tree’s crop virtually seedless and describes hints of raspberry (2:14–2:18). These are reports about this individual container tree and its crop, not a cultivar-wide yield or cold threshold.

Summary from transcript: 38:28 video; English auto-generated captions cover 0:01–38:28; page displays “4 years ago” without an exact publication date. In the presenter’s Southern California collection, the Moro is on standard rootstock; the presenter says standard-rootstock trees can reach 25 ft tall and wide (0:01–0:15). The year described was a heavy-bearing year, with smaller-than-usual fruit (1:28–2:21). The presenter harvests fruit and brings it into a greenhouse for comparison (1:28–1:55). In this fruit assessment, he describes easy separation of the segments and very juicy flesh (10:31–11:05), with tartness and enough sweetness to avoid a puckering response (11:07–11:25). He says a seed may occasionally be found in Moro (13:37–14:03). The comments describe this grower’s collection and tasting; they are not a calibrated cultivar-wide sensory measure or yield.

Summary from transcript: 2:57 video; English auto-generated captions cover 0:00–2:56; page displays “4 years ago” without an exact publication date. The presenter describes a three-year-old Moro in a container against the south wall of the house (0:49–1:18). He reports several nights with air temperatures of 25–28°F and says the tree was “doing just fine”; he had not brought it indoors that winter, but would do so for a forecast below 25°F (1:08–1:30). Duration and exact site minimum are not given; this is a report about one protected container specimen, not an unprotected cultivar threshold. The shown fruit is called virtually seed-free (2:06–2:14). The presenter describes it as very sweet with an acid bite and raspberry-like flavor (2:19–2:33), without a distinct sourness intensity rating.

Summary from transcript: In the Moro segment (2:37–5:17), the home grower says a greenhouse reached 30°F and the tree still fruited. Site, rootstock, exposure date and duration, and injury assessment are unstated; this is one protected-tree report, not a cold threshold.
