US-1282 Citrandarin

US-1282 is a USDA citrandarin from a 1995 Cleopatra mandarin × Gotha Road #6 trifoliate orange cross at A.H. Whitmore Foundation Farm. It was released in September 2014 as a citrus rootstock.^⁠[2]⁠[8]

Hamlin orange trees on US-1282 outyielded Swingle in a Florida flatwoods trial affected by HLB. These results concern grafted Hamlin trees at one site and reflect tolerance after infection rather than resistance to infection.^⁠[2]⁠[8]

A 2020 nursery study found no true-to-type seedlings in its US-1282 sample of 107 planted seeds, including a separate check of 24 visually selected seedlings with DNA markers. The authors recommended cuttings or micropropagation for maintaining this rootstock; the result comes from one open-pollinated seed collection.^⁠[5]

The Mulberries tested one of the first fruits from a Pennsylvania US-1282 plant, reporting a weight of 22 g, 13 °Brix, and dry, sour flesh. The video, scorecard, and forum tasting may describe the same fruit and should be read as overlapping reports rather than independent samples.^{⁠[7]⁠[4]⁠[1]}
