World of CitrusUS-1284 Citrandarin
US-1284 Citrandarin originated from a 1995 cross of Ninkat mandarin and Gotha Road #6 trifoliate orange made by Dr. Kim D. Bowman at the A.H. Whitmore Foundation Farm. During field testing, the selection was identified as BS95-V6-24.
Made the 1995 Ninkat mandarin × Gotha Road #6 trifoliate orange cross that produced US-1284 Citrandarin.
The USDA Agricultural Research Service released US-1284 Citrandarin to nurserymen and growers for commercial use in Florida to address the need for rootstocks with improved HLB tolerance. The official release identifies Kim D. Bowman as field-testing lead and Greg McCollum as collaborator in fruit-quality evaluation. In the St. Lucie flatwoods trial, Hamlin on US-1284 yielded 63 kg/tree in 2013 after Las infection and improved nutrition; the Water Conserv II ridge trial showed no consistent yield advantage over Swingle across reported years, with a significant difference only in 2009. These are site-specific grafted-scion results, not fruit traits of US-1284.
Released US-1284 Citrandarin for commercial use in September 2014.
Planned and conducted selection, evaluation, and field testing of US-1284 Citrandarin before its release.
