Summary from transcript: the speaker names Miyagawa at 4:30 among earlier-maturing Satsuma clones and says it ripens three or four weeks earlier than standard Owari in the described south-coastal B.C. context. Preserve this as a source-reported comparison; its own sample, rootstock, tree age, protection, and measurement method are not supplied.

Primary paper, pp. 17–18. Miyagawa-Wase is the parental line in Nishiura's comparison with the nucellar selections later named Miho-Wase and Okitsu-Wase. The paper reports their more vigorous growth, earlier and more uniform coloring, flatter fruit, and higher soluble solids than Miyagawa; it reports Miho lowest and Okitsu highest in citric acid. Pollen mentioned in the 1940 experiment does not establish genetic parentage.

UGA Circular 1352 compares 12 early-maturing satsumas with Owari across southern Georgia. Each cultivar was sampled at 1–5 sites; five fruit per variety and site were juiced at late September and mid-October in 2022 and 2023, with the same sites both years. Values are multi-year means. Rootstocks included Poncirus trifoliata, ‘Rubidoux,’ and trifoliate hybrids, but cultivar-specific assignments are not stated. TSS/Brix and titratable acidity are chemical measurements, not pH or sensory scores. The publication does not identify a matching CRC accession.

The CCPP availability table on printed p. 4 lists this cultivar in its “Seedless Varieties” column. The table defines “seedless” as allowing only an occasional seed, regardless of planting location. This is a collection availability classification, not a counted sample, accession-specific trial, or observation of the catalog's plant.

The abstract reports a Miyagawa Wase Satsuma mandarin genome assembly analyzed by trio binning with parental genomes labeled Kishu (C. kinokuni) and Kunenbo (C. nobilis). It provides no accession identifiers for those parental genomes and does not establish a match to this catalog's Miyagawa propagation material. This citation records the study-specific sample and labels; it does not alter the catalog's recorded relationships.

Citrus ID Edition 2 entry (October 2011); no individual author is displayed. It lists the synonyms “Miyagawa Wase” and “Miyagoma (sec. Cottin 2002)” and gives general key-based and historical cultivar descriptions. Its origin account is explicitly attributed to Hodgson (1967), including the reported Fukuoka Zairai limb sport and 1923 naming/introduction; this is not independent confirmation or an accession record. The entry does not identify UCR CRC 4074 or establish that catalog propagation material matches the described plant.

ResearchGate publication page for the article (the supplied Figure 1 URL resolves here); DOI 10.22059/ijhs.2018.261277.1470, Iranian Journal of Horticultural Science 50(3), Autumn 2019, pp. 683–695. The visible article byline lists Negin Akhlaghi Amiri. Its abstract describes an eight-year (2010–2017) randomized complete-block study in East Mazandaran of early-maturing Miyagawa Satsuma on six named rootstocks, with four replications and four trees per replication; it does not explicitly report a total sample count. Figure 1 is captioned as a July 2015 field image at GhaemShahr horticultural research station. The source does not identify a matching CRC accession or prove the catalog plant shares the study scion/rootstock.

The archived post by ahhhhere is displayed as “3y ago”; no exact publication date is shown. The title labels the tree as Miyagawa satsuma. The poster says they have had it about eight months, that some fruit are “pretty big” and nearly ripe, and hopes the fruit ripen before a prospective −2 °C freeze. In a reply, the poster places themselves near the Laois/Kilkenny border and says the satsuma came from a friend; the poster also mentions keeping plants under 2 ft in a small plastic greenhouse but does not specify whether this satsuma was outdoors or protected. Time in possession is not tree age; the freeze is not a recorded exposure. Accession, rootstock, fruit measurement, harvest and tasting are not reported.

The page heading identifies Citrus unshiu ‘miyagawa’. Its profile describes a medium-sized, weeping tree with white flowers; fruit is described as fairly large for a mandarin, seedless and very juicy, with flowering in March–April and harvest in November–December. The title advertises −12°, while the prose lists hardiness as −8/−10 °C. No author, publication date, specimen/accession, location, method, exposure duration or measured sample is provided; these are untested profile claims, not measured hardiness or a confirmed observation of UCR CRC 4074.

Summary from transcript: In this 2:30 video, the presenter shows a tree and fruit titled “Miyagawa satsuma,” though the auto-captions render the name as “Miga” or “Migua.” The presenter calls it a good producer and relatively small for them, and describes the displayed fruit as easy to peel, relatively seedless with occasional seeds, juicy and sweet. Captions are English, auto-generated, and cover 0:01–2:27. The page shows “1 year ago,” not an exact publication date. No accession, rootstock, tree age, observation date/location, sample count, measured yield, Brix or pH is stated; “sweet” is an unscored plain-language impression.

Masao Nishiura, “Citrus Breeding and Bud Selection in Japan,” Proceedings of the Florida State Horticultural Society 77 (1964), pp. 79–83. On printed p. 80, under “Development of New Satsuma Varieties through Limb Sports,” Nishiura reports that Miyagawa-Wase appeared as a limb sport from Zairai in 1915 and was introduced by Tanaka in 1923. This supports the cataloged year for the Miyagawa origin event; it does not establish a sexual parentage cross.
