Summary from transcript: The speaker identifies one W. Murcott tree in their garden. They report the site reaches about 25°F in USDA zone 9a with no winter dieback observed on this tree; this is an individual location report, not a controlled hardiness threshold. The speaker recalls variable prior crops and a heavy current fruit set. They say the tree was planted in 2017 and call the current season its sixth year, then estimate it at about seven years old; these recollections do not establish an exact age or planting year. The grower estimates the tree at about 6.5 feet tall. In a tasting of fruit from that tree, they describe it as easy to peel, very juicy, and “pretty sweet”; some fruit are described as about orange-sized, with a flat base and oblong top. The video gives no measured fruit weight, Brix, or standardized taste score. Captions 0:10–0:46, 0:50–1:52, and 1:52–2:25; exact upload date unverified.

The release identifies W. Murcott as Afourer and reports late maturity, good color, production, appearance and taste; it says the cultivar is mostly seedless when sufficiently isolated from pollen-producing citrus. It describes a randomized Lindcove planting established in the mid-1990s: in December 2007, most sampled trees had thin canopies and branch dieback, with either very low or very high yields across C-35, Carrizo and trifoliate rootstocks. The author says the cause was not known for sure and reports strong alternate bearing. These are bounded observations and advice from one California planting, not a cultivar-wide failure claim.

The article reports an Ege University W. Murcott orchard study in Aydın Province, Türkiye, during 2024–25. It summarizes two 27 mg/L preharvest silicon sprays around color break, a 3-minute 2 mM salicylic-acid dip or untreated control, and storage at 41°F/90% RH for 12 weeks. Reported outcomes include average fruit weight of 100.53 g for silicon-treated trees versus 89.55 g untreated and maturity index 8.08 for combined Si+SA versus 9.19 untreated after storage. Fruit count and full sample size were not available in the article; results are treatment- and storage-specific.

Original article, Acta Horticulturae 1065 (2015), 543–548; full text retrieved from the author-content page, while the supplied ResearchGate figure URL points to Figure 2. The study irradiated W. Murcott budwood, grafted material to rootstocks, and evaluated seed content in field-grown plants in Pomaire, Chile. It reports 2,183 W. Murcott plants and 319 candidate selections in the 2011 screening; Figure 2 contrasts a low-seeded derived selection with a test plant. These are individual plant measurements, not cultivar-wide values. The authors say mutation stability was still being evaluated. Do not transfer selection-specific seed counts to the base cultivar.

Dissertation, UC Riverside, June 2018. Its abstract describes Tango as a low-seeded mutant derived by gamma-irradiating W. Murcott budwood and compares leaf DNA from the two. It reports three SNPs and seven indels heterozygous in Tango and homozygous in W. Murcott, as well as Tango-specific chromosome rearrangements. This supports treating Tango as a distinct mutation-derived selection; it does not establish W. Murcott's pollen parent or ancestry proportions.

The publisher page provides the article's abstract but not full methods or sample counts. It describes W. Murcott scions on Bitters, Carpenter and Furr trifoliate hybrids and local sour orange under Adana, Türkiye conditions. The abstract reports rootstock effects on leaf chlorophyll and fluorescence; local sour orange had higher net photosynthesis, while fruit from Furr showed slight weight and diameter increases. Rootstock-associated citric acid values ranged from 0.68% on Bitters to 0.78% on local sour orange. These are abstract-level rootstock comparisons, not baseline W. Murcott measurements.
