Hamlin sweet-orange yield on rootstocks in two Florida trials; performance depended on site, disease and management. Values describe grafted scion trees, not rootstock fruit traits.

The index lists US-1282 parentage as Citrus reticulata ‘Cleopatra’ × Poncirus trifoliata ‘Gotha Road’ and its USDA release date as 2014. The table does not report selection, field performance, release contributors, or other historical events.

Individual scorecard image for US-1282 Citrandarin. The printed preference ratings are sweetness 6.5/10, sourness 2/10 and bitterness 6/10; 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.

Study of own-rootstock fruit, seed and nursery progeny from four-year-old grafted US-1282 seed trees at the USDA A.H. Whitmore Foundation Farm, Leesburg, Florida; fruit collected January 2019. Tables report fruit and seed measurements and one planted seed lot. SSR results concern 24 seedlings visually selected as closest to true-to-type, not a random sample or a rate for the whole seed lot. The article was also reprinted in Proc. Fla. State Hort. Soc. 132 (2019); this DOI identifies the HortScience publication of the same study.

In forum post #8, kumin describes an individual US-1282 plant in soil in a tunnel with minimal heat activated below 20°F and says US-1282 had not fruited as of the post date. This is a first-hand report about one protected plant; the temperature is a heating trigger, not a recorded exposure or outdoor hardiness threshold.

Summary from transcript: presenter identifies one US-1282 fruit supplied by Mel in Pennsylvania, among the first fruit from that plant; records 22 g and 13 °Brix and gives subjective sensory ratings. The ratings and Brix correspond to the existing US-1282 scorecard/TFF reporting; treat these as likely overlapping reports rather than independent samples. Presenter’s spoken “Nat” mandarin parentage claim conflicts with the cited breeding record and is unverified. English auto-generated captions.

Official 6-page USDA-ARS release document; reviewed copy has no legible publication/signature date. Page 1 identifies the 1995 Cleopatra mandarin × Gotha Road #6 trifoliate-orange cross at A.H. Whitmore Foundation Farm; selection code BS95-V5-78; Kim D. Bowman’s field-testing role and Greg McCollum’s fruit-quality evaluation role. Pages 1–2 describe Hamlin scion field trials, including seven St. Lucie flatwoods trees per rootstock and 2013 yield of 63 kg/tree on US-1282 versus 19 on Swingle. These are grafted scion results; the document interprets performance under HLB as relative tolerance after infection, not resistance. The associated already-cited 2015 article provides the September 2014 release date.

Post #572315 compares US-1282 with Bishop and US-1279 fruit, described as somewhat immature and affected by excessive shade. It calls US-1282 the smallest of the three and reports that its tree was productive of small fruit; no count or dimensions are supplied. The author also describes its seedlings as wholly zygotic, an unverified progeny assessment rather than genetic testing. Relative flavor preference is not an intensity score.

Kumin reports cold damage to US-1282 in a high tunnel and suggests late-season flushing as a major contributor. The post gives no temperature or exposure duration and does not establish a general outdoor hardiness threshold.

Kumin compared US-1282 fruit by ripeness and seed presence, reporting that riper seeded fruit tasted better than seedless and immature fruit. The post does not give a sample count or standardized taste score; the comparison is the grower’s report.
