Genome resource reviewed against the CGD assembly record and existing variety identity. CGD identifies the sequenced material as Valencia. This is a cultivar-level match; the record does not establish that a particular accession or tree represented here was sequenced.

Full author-uploaded article text reviewed. The trial compares Valencia and an unnamed nucellar mid-season sweet-orange scion across rootstocks at Davenport, Florida. Its qualitative result describes Rusk as semi-dwarf for both scions, while noting possible environmental effects on droughty soil. No table measurements are imported here; these are scion/rootstock trial observations, not Valencia own-root traits.

Full text reviewed. The Florida factorial trial begun in 1980 compared Hamlin and Valencia scions on Rusk citrange or Milam lemon under different topping heights and spacings. The paper characterizes Rusk as moderately vigorous and reports smaller trees and improved yield, fruit quality, and economic return relative to Milam. These are grafted-tree outcomes; no table values or sensory scores are imported.

Evidence reviewed from the abstract on printed p. 449 only; the available PDF extraction contains the preceding sour-cherry paper and only this final Yelenosky page, not the full article or tables. It describes potted Valencia on Rusk rootstocks after controlled cold conditioning. No carbohydrate-table values are imported, and this is not an outdoor hardiness threshold for Valencia or Rusk.

The greenhouse study grafted Valencia sweet-orange scions onto selected open-pollinated S10 seedling rootstock lines under salt-stress and HLB treatments. Results concern those graft combinations, not Valencia's inherent stress tolerance.

Article includes historical citrus rootstock trials; variety evidence is restricted to the generic Valencia scion on Troyer in the 1945 Fillmore trial.

The Valencia profile distinguishes Spanish Valencia Temprana from the commercial Valencia orange. It reports Rivers importing the variety from the Azores and cataloguing it as Excelsior in 1865, and attributes “Valencia Late” to a California naming account. Hodgson says evidence does not support the common Spanish-origin assumption and considers Portugal probable. This is an attributed 1967 historical account, not genetic confirmation; the exact printed page was not verified.

Summary from transcript: English auto-generated captions, 0:00–6:22 of 6:23, reviewed. The presenter identifies the tree as Campbell Valencia and reports late-season harvest, fruit profile and juice observations from that garden tree. These observations are source-specific and do not identify a particular accession, rootstock or exact location; they do not describe Frost Valencia.

Summary from transcript: English auto-generated captions, 0:00–3:25 of 3:30, reviewed. The presenter reports on their Valencia orange tree: in March it still carries prior-season fruit, is described as at least 30 years old, and is said to have survived an unspecified frost. The presenter says the tree is in zone 9B, but gives no exact location, frost temperature/date or damage assessment. This is a single grower report, not evidence about Frost Valencia.

The consumer article gives a secondary account of Valencia's naming and general season/keeping claims. It describes Valencia oranges generally, not Frost Valencia, and supplies no defined sample, method or trial. Treat its historical narrative as an attributed account and do not interpret comparative sweetness or juice language as measured fruit evidence.

One-page discussion with posts by sunny, Oolie and Mark in Texas. Some messages ask questions or speculate; a reply gives general Valencia late-season/juice/seed claims and conditional cold-hardiness advice without a named tree, documented event or method. No post identifies Frost Valencia. Treat all claims as attributed forum statements, not measured cultivar trials.

Post 3 is a progress photo captioned “One month later,” read with the topic's February nursery-acquisition and March flowering context. The author labels the plant Valencia Orange but gives no rootstock, verified accession, fruit-quality result or textual phenotype measurement; this is not Frost Valencia evidence.

The thread reports one owner’s nearly ten-year-old tree whose fruit was described as sour; a later reply only hypothesizes that the Valencia graft may have failed and sour-orange rootstock become dominant. Neither the cultivar/accession identity nor that diagnosis is independently verified. No post identifies Frost Valencia.

Summary from transcript: Native English timestamped transcript, Valencia-named segment at 10:24–11:44 reviewed; transcript extraction is partial and caption provenance is not shown. The speaker calls the displayed Valencia fruit firm to pressure, describes Valencia as summer-ripening, and predicts that the displayed fruit will peak in ripeness in about a month. Sample date, count, rootstock and Frost-selection identity are unspecified; this is not Frost Valencia evidence.

Reports adjacent Valencia trees on rough lemon in the same Orie Lee Family Groves block at St. Cloud averaged approximately 6 lb solids per box over the four-season report, compared with OLL-8 on rough lemon at 7 lb. No Valencia-specific sample count, trial design, harvest dates, or season-to-calendar-year mapping is given.

Reports OLL-8 juice on rough lemon at 1.0 lb solids per box above standard Valencia on rough lemon over four consecutive seasons. This appears to be the same reported comparison summarized in the 2023 Citrus Industry article; treat as a repeated report, not an independent second sample.

Full article, Proc. Fla. State Hort. Soc. 99:33–35 (1986), reviewed. Table 1 reports a grafted Valencia sweet-orange scion trial at St. Cloud, Florida: planted in 1978; irrigated and nonirrigated treatments; split-plot design with four replications of two-tree units. Reported outcomes include tree yield, cumulative yield, soluble-solids percentage and pounds of solids per box, tree height, and yield efficiency. These are Valencia scion/rootstock trial results, not fruit measurements of Rangpur × Troyer.
