Genome resource reviewed against the CGD assembly record and existing variety identity. The reference derives from a haploid Clemenules clementine; this cultivar match does not identify a particular living tree in the app.

Cultivar-characterization experiment. Its Nules findings concern healthy trees on Carrizo citrange at El Guerdane, Souss Valley, Morocco, with fruit means from 2004–05 and 2005–06; do not transfer these trial measurements to an unverified clone or growing site.

Commercial variety profile. Reports large, somewhat flattened fruit, juicy high-quality pulp and easy peeling; describes the fruit as practically seedless while noting cross-pollination can produce seeds. Gives fruit size, weight, juice and harvest ranges, crop timing and productivity claims, and reports origin as a mutation of Clementina Fina at Nules, Castellón. No sample, growing site or measurement method is supplied; numeric values are source-reported profile values.

Plant listing for Clementine de Nules / Clemenules. Fruit, tree and cultivation description is attributed to Cistus Nursery, a nursery contributor rather than a page author: qualitative sweet, juicy and seedless fruit; vigorous tree and cultivation guidance. Listing fields include mature size, USDA zones 9b–11 and sun exposure. These are nursery/listing guidance, not measured thresholds; no climate, rootstock or sample provenance is supplied. Sweetness wording is subjective and unscored.

Summary from transcript: Partial native closed-caption samples in English at approximately 0:57 and 1:21–1:51. At 0:57, jesen84 says the small piece has quite a few seeds; at 1:21 he calls the seed amount a deal-breaker, then considers nursery mislabeling or cross-pollination as possible explanations and says he is unsure. Captions are partial and do not establish the tasted fruit’s cultivar identity.

hoosierquilt reply dated July 30, 2015, in the “Ponkan Tangerine” topic. The captured topic passage says: “My Clemenules are super sweet and I don’t have any sort of bitter aftertaste at all.” Personal report about the grower's fruit; the exact fruit sample, site, tree, rootstock, harvest date, and tasting method are not supplied. The accompanying archive includes this July 30 reply in the visible discussion context at the cited topic URL.

Primary experimental study. Clemenules evidence: Plant Material; Evaluation of in planta Pollen Grain Germination; Table 1; Discussion: Pollen Performance Differed Across Ploidy Levels. Original diploid trees and a separate colchicine-derived doubled-diploid line at IVIA, Moncada, Valencia, Spain. Germination on Fortune stigmas is a pollen assay, not a zygotic-seedling or cross-success rate. Source capture: docs/research/breeding-keywords-2026-10-10/lora-2022.html.

Primary study. Materials and Methods explicitly name Clemenules among five non-apomictic clementine genotypes. The study's 2x × 4x hybridization results include Clemenules; its abstract reports that plants from the same undeveloped seed arose through cleavage of the original zygotic embryo. It also finds that plants recovered through in vitro nucellus culture matched the zygotic embryo genotype. These are special hybridization and culture findings, not a denominator-based rate for ordinary open-pollinated seeds; they support the categorical non-apomictic classification, not a measured percentage.
