UFR-14

UFR-14 is a citrus rootstock identified as FG 1733 in the UF/IFAS St. Helena survey at Dundee, Florida. The report calls it a putative pummelo/mandarin hybrid and lists it with Valquarius sweet orange in the 2008 planting.^⁠[1]

The report's interpretive summary identifies UFR-14 as promising for yield and soluble solids in grafted sweet-orange trees, while noting difficulty establishing it through tissue culture. These are observations from the St. Helena survey; the report does not give an individual release date.^⁠[1]
