USPP34493P2, application 17/300,785. Patent reports an open-pollinated Citrus inodora clone ‘80-527A’ seedling as seed parent and Citrus australasica var. sanguinea ‘DPI 50-36’ as pollen parent; the seedling’s pollen parent is unknown. Fruit and tree measurements are specific to the described six-year-old Carrizo-budded Lake Alfred specimen. Experimental tetraploid findings are separate.

UF/IFAS field-day slides report SunLime fruit weight 26.14–34.66 g, length 2.8–3 inches and 0–6 seeds (slide 13). Slide 12 describes a medium bush, seven-year Lake Alfred tree about 8 ft, sporadic year-round flowering with February–March main bloom and limited yield data (about 150 fruit for a six-year tree). Slides 29–32 show a comparative 2022 freeze-response study and say preliminary data suggest SunLime better cold tolerance than RedLime; no cultivar-specific hardiness threshold is stated. Cover prints October 2024 23; day is not normalized.

158:31 (2024). Abstract describes oryzalin-induced autotetraploids of UF SunLime, confirmed by flow cytometry, and cold-stress physiological responses. This experimental induced-tetraploid material is separate from the baseline diploid cultivar; opened article page exposes abstract but not full tables or methods.

Visible slide 11 reports SunLime weight 26.14–34.66 g, length 2.8–3 inches and 0–6 seeds; slide 12 reports a medium scraggly bush, seven-year Lake Alfred tree about 8 ft, limited yield data and about 150 fruit from a six-year tree. Rootstock, sample count and measurement protocol are absent; preserve as a distinct 2023 snapshot.

Secondary report of Manjul Dutt’s March 23, 2022 symposium statements: UF SunLime and RedLime were released in 2021 and reportedly grow in Central/South Florida on standard citrus rootstocks; report gives an estimated 7–10 statewide acres. It attributes very small amounts of HLB in SunLime testing; no assay, cohort, count or threshold details, so this is not evidence of immunity.

Report on Manjul Dutt’s December 20, 2023 CREC presentation: SunLime described as a medium bush, about 8 ft at seven years and about 150 fruit at six years. No rootstock or sample details are stated. The program goal of developing disease-resistant varieties is not evidence of cultivar resistance.

Official cultivar page reports a medium scraggly bush, six-year plants about 7 ft, sporadic year-round bloom with February–March main bloom; fruit 20–34 g, length 2.7–3.1 inches (occasionally at least 4 inches), 0–7 seeds and about 150 fruit at six years (limited data). Also reports no observed graft incompatibility and easy propagation on standard citrus rootstocks. Page shows last modified 2026-08-24 but no publication date. HLB/Ct and scab statements retain attribution and lack assay/cohort details; do not infer full ancestry.

Article describes SunLime as a hybrid, 2.7–3.1 inches, averaging 30.4 g, up to five seeds, HLB-tolerant and scab-susceptible; it does not state the pedigree. Reported nine-in-ten red-color preference is an informal color survey, not sensory measurement.

Report of April 24 UF/IFAS field day and Ballen’s market feedback: 134 industry participants and consumer survey of 573 festival surveys rated SunLime color/flavor/acidity/appearance favorably. Ratings are marketing preference, not specimen chemistry or controlled taste tests; reported consumer likelihood counts do not sum to 573, so retain figures without recalculation.

Summary from transcript: At 11:32–12:29 presenter reports SunLime fruit weight 26.14–34.66 g, length 2.8–3 inches and 0–6 seeds; at 14:40–15:01 estimates about 150 fruit from a six-year-old tree. At 24:04–24:39 gives preliminary multi-site HLB test statements, but auto-captions render Ct as city and assay/sample details are absent; retain only as attributed initial data, never definitive tolerance/resistance. Transcript has recognition errors and does not establish parentage.
