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-1284 parentage as Citrus reticulata ‘Ninkat’ × 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.

Primary study of rootstock fruit, seed, and seedling nursery traits. US-1284-specific results are from Table 1 (Ninkat × Gotha Road; release year 2014), Table 3 (rootstock fruit/seed traits), Tables 4 and 7 (seedling assessment). Fruit came from four-year-old grafted seed trees at A.H. Whitmore Foundation Farm, Leesburg, Florida; nursery seedlings were grown at the USDA U.S. Horticultural Research Laboratory, Fort Pierce, Florida. These results concern rootstock fruit and nursery progeny, not a grafted scion.

Summary from transcript: At 13:08–13:19, the grower identifies US-1284 in a makeshift bottle greenhouse and reports dieback to ground level at 2°F, with another dieback at 5°F. Event dates, exposure duration, plant age, graft status, and exact site are not stated; this is an attributed specimen report, not a cultivar hardiness limit. The unlabeled graft tentatively discussed at 12:29–12:55 is explicitly uncertain and excluded.

Summary from transcript: At 2:17–2:40, the grower identifies US-1284 as the rootstock of a Satsuma. The speaker reports that the potted plant developed rot, then a basal cutting was rooted and shown about two years later; it had died to ground level at an unspecified point and resprouted. The interval between dieback and resprouting is unstated; no temperature or event conditions are given. This may describe the same specimen as source #4, not an independent plant. The caption phrase about the Satsuma being “not grafted on a lemon” is garbled and excluded.

Official primary 3-page USDA-ARS release followed by a 4-page table addendum (headed Kim D. Bowman and Greg McCollum; footer marked Bowman 2014). The cover signature/date line is blank, so no exact publication date is asserted. Page 1 identifies the 1995 Ninkat × Gotha Road #6 cross at A.H. Whitmore Foundation Farm, Kim D. Bowman’s making and field-testing roles, collaborators including Greg McCollum’s fruit-quality evaluation role, and designation BS95-V6-24/US-1284. Describes grafted Hamlin field trials and scion fruit quality; not rootstock own-fruit traits.
