Sherman

Sherman is an early sweet-orange-like citrus selection from José Chaparro’s UF/IFAS Gainesville breeding program. Published accounts describe October ripening, deciduous and thorny trees, and seedy fruit. Reported juice readings are approximately 12 °Brix with a ratio of 14.5–14.8. Its parentage is not established by the reviewed sources.^⁠[1]⁠[2]

Sherman is described as cold hardy and canker susceptible, but no measured cold-exposure temperature is available in these sources. Researchers reported incompatibility with US-942: affected grafts developed swelling above the union, a necrotic ring, chlorosis, stunting and premature scion death. DPI indexing did not detect viruses in the tested scions.^⁠[1]⁠[3]

An August 2021 program account describes trials at the Indian River Research and Education Center and Gainesville Teaching Grove being evaluated to facilitate release. A November 2021 report calls Sherman recently released; a January 2022 account describes it as released and cleaned. The exact release date remains unverified.^{⁠[2]⁠[3]⁠[1]}

Possible identity — unconfirmed: UFGNV0187 is a plausible original code for Sherman. CRDF’s March 2021 profile, submitted by Chaparro, closely matches its early maturity, deciduous habit, thorniness, seeds, canker susceptibility and US-942 incompatibility. It reports 11.6 °Brix averaged over six seasons and a ratio of 14.71. No reviewed source explicitly equates the names. UFGNV0187’s additional US-897 incompatibility and other measurements must therefore not be treated as verified Sherman traits.^{⁠[1]⁠[3]⁠[4]⁠[5]}

A 2022 report mentions Sherman being displayed in October, but does not identify the specific display event.^⁠[1]⁠[6]
