Pages 49–50 report Robinson (Orlando No. 426-7-4) as one of 327 seedlings from Clementine (female) × Orlando tangelo. The paper provides historical Florida observations of this individual selection; it is not a molecular parentage study.

Secondary cultivar record. The Robinson description is attributed to Hodgson (1967); its Origin passage presents self-incompatibility/cross-pollination as an expectation inferred from the parents, not a direct Robinson trial. The 2010 Chiefland paragraph concerns clone SPB-800-3 and should remain clone-specific. Preserve separate taxonomy/origin attributions rather than treating this record as genomic proof.

UF/IFAS extension fact sheet. Reports the Clementine × Orlando cross in 1942 and 1959 release. Describes seed content as highly variable with cross-pollination; no-pollinizer trees as very light-cropping, with small, few-seeded fruit; nearby pollenizers can raise set, fruit size and seed count. Includes an October–December harvest window and splitting/drying/cultivation warnings. Extension guidance, not a controlled trial; preserve source-specific conditions.

Full article, methods and tables retrieved. Dörtyol, Hatay, 2002–2007; Robinson scion on sour orange, Carrizo and Troyer, with Valencia pollinizers maintained nearby. Annual late-November harvest; 20 fruit per tree sampled for quality. Six-year results report no rootstock effect on Robinson fruit weight/diameter and similar averaged quality measures, while seed count differed; cumulative yield was highest on Carrizo and lowest on Troyer in this trial. Analytical TSS/acidity are not sensory taste scores or fruit pH. Keep Nova results separate. Supplied #11 and #12 are alternate records of this same article, not separate studies.

Full article retrieved from an alternate journal mirror after the supplied ALÖKI PDF returned 403; DOI and document identity match the supplied PDF. Study used 22-year-old Robinson trees in 2014, single/double girdling at anthesis versus control, 10 trees per treatment, and December harvest. Double girdling ranked highest for yield and marketable fruit size; internal-quality differences were not significant. Treatment-specific orchard results, not a cultivar-wide fruit description. The methods contain an apparent “grapefruits” typo for sampled Robinson fruit; do not repeat it as specimen identity.

AGRIS metadata and abstract retrieved; publisher full text not retrieved. Dörtyol-Hatay leaf-nutrition study across scions/rootstocks. Abstract reports Robinson/Carrizo N 2.02%, Robinson/Carrizo K 1.10%, and Robinson/Troyer Ca 3.48%. Do not assign pooled P/Mg ranges to Robinson; these are leaf nutrients, not fruit quality or taste. Abstract gives no per-treatment sample counts.

Full article retrieved from supplied DergiPark PDF #9. Dörtyol, Turkey, 2010–2011; grafted Robinson/Fremont on sour orange. Hand-pollination treatments used three trees and about 100 flowers per treatment; fruit-quality sampling was 20 fruit per cross-combination. Robinson maturity fruit set was 23.08% with Valencia Late pollen versus 3.50% open-pollinated (Table 1, p. 109). Table 2 reports Robinson weight highest with Rhode Red Valencia (137.49 g) and seed count highest with Valencia Late (27.81); distinguish these study results from cultivar-wide expectations. Supplied #6 is a ResearchGate duplicate/mismatched publication ID for this paper, not an independent study.

Article metadata and abstract retrieved. Dörtyol, Turkey, 2010–2011; leaf carbohydrate measurements on Fremont, Nova and Robinson across three rootstocks. Robinson total leaf carbohydrate reached its seasonal low in July; overall seasonal pattern declined through summer and rose in autumn. This concerns leaves, not fruit sugars, TSS, or eating quality; retain Nova/Fremont results separately.

Peer-reviewed study of Fortune, Robinson and Osceola scions on sour-orange rootstock at Ramsar. Fruit was collected in the last week of January 2014; Table 4 reports juice chemistry and Table 2/3 report cold-pressed peel-oil constituents. Preserve the sample, table and unit context; peel-oil composition is not juice chemistry, sensory taste, disease response or hardiness evidence.
