Genome resource reviewed against the CGD assembly record and existing variety identity. This USDA Mexican-lime assembly provides a reference for Citrus × aurantiifolia, also called Key or West Indian lime. The app’s record is not established as the particular material sequenced in PRJNA1137419.

This article is a rootstock trial. The Mexican lime scion was accession SRA 140 (diploid), grafted onto diploid or tetraploid Swingle 4475. The paper treats this trial accession; it does not establish that it is identical to the catalog’s broader Key/Mexican lime entry.

UF/IFAS home-landscape guidance for Key Lime, not an accession-specific account. The associated PDF says originally published February 1991, revised December 2010 and November 2016, reviewed December 2019. It states that Spanish and Portuguese explorers brought the lime to the Americas in the early sixteenth century, conflicting with the existing overview’s late-fifteenth-century wording. It describes ordinary trees as small and thorny, while separately describing spineless selections as more upright/compact, darker-leaved and low-producing; that generic statement does not establish traits of CRC 2683. Its fruit, cold, and propagation figures are general species guidance rather than measurements of a catalog accession.

General species-level plant guide that identifies Key Lime and Mexican Lime as common names; it does not describe Thornless Key Lime or establish a bud-sport relationship. It describes the plant as a vigorous shrub or small tree with green-to-yellow ripe, juicy, aromatic fruit; structured fields characterize fruit as spherical and seedy and list thorns/spines. The listed dimensions, zones, origin, and cultivation guidance are species-level entries, not measurements of a particular accession or thornless selection. No author or publication date was visible on the reviewed page.

Summary from transcript: English auto-generated captions, 0:00–13:11 of 13:25. A home grower shares Key Lime cultivation advice based on their own tree; they do not identify its rootstock or planting date. At 5:33–7:15, the speaker describes Key Lime as cold-sensitive and recommends moving a potted tree into shelter/garage when forecasts approach 40°F. This is the speaker’s advice, not a documented damage event or measured cold-hardiness threshold. No Thornless selection or direct tasting is discussed.

Summary from transcript: English auto-generated captions, 0:01–5:02 of 5:03. The grower identifies a Mexican Key Lime in a 40-gallon container, estimated at about 5 feet wide and 6 feet 4 inches high, in its third year (0:25–1:01). They say they water it twice daily and can pick its small fruit any time of year. The speaker calls the aroma and taste exquisite (1:44–1:53), which is non-calibrated praise and does not support a taste-intensity score. The speaker says young Mexican Key Limes may lose leaves in winter but gives no temperature or documented damage event. No Thornless selection is described.

Summary from transcript: English auto-generated captions, 0:00–9:50 of 9:55. The speaker identifies a South Florida garden in USDA zones 10A/10B and says they have grown citrus for about eight years and maintain over 100 plants. They describe insect-exclusion cup/box systems used for about three years to manage greening/pests (2:49–3:19). This is the grower’s pest-management practice, not evidence of cold protection, disease resistance, or a measured Key Lime outcome. No direct fruit sample or cold-injury threshold is reported; no Thornless selection is mentioned.

Summary from transcript: English auto-generated captions, 0:03–9:18 of 9:20. At 4:59–6:11, the presenter tastes a Key Lime sample from a mixed haul including fruit from several locations; the exact source of this sample and its maturity are not established. The presenter describes Key Lime as smaller than Persian/Tahitian lime and says it is “said to be” more intense and more seeded, marking those comparisons as hearsay. They describe thin skin and call the tasted fruit “sour,” “really really sort of sharp and acidic.” This is one sample observation; no sweetness or bitterness intensity is given, and no Thornless selection is identified.

Summary from transcript: English auto-generated captions, 0:02–4:50 of 4:54. The speaker identifies the shown tree as the thorn variety of Mexican Lime and says a thornless variety is available (0:15–0:29), but does not show or describe a separate thornless specimen. For the thorned tree, the speaker estimates fruit at roughly 1.5–2 inches and describes roundish, thin-skinned, juicy, aromatic fruit (0:30–0:50), with yellow ripening fruit in a Southern California garden in early December (1:06–1:35). They report this thorned tree had been in ground about five years and producing for four years (4:23–4:38). No taste-intensity score or cold event is reported; do not transfer its observations to Thornless Key Lime.

Summary from transcript: English auto-generated captions, 0:00–0:22 of 0:27. The speaker identifies Mexican Lime as also called Key Lime and bartender’s lime. They describe fruit as fragrant and very tasty with slight tartness (0:15–0:22); no sweetness or bitterness intensity is stated. No tree, sample date/location, maturity, or measured fruit context is supplied, and no Thornless selection is identified.

Description-based evidence only; no usable captions or transcript were available. The channel description says the video revisits a neighbor’s Mexican lime cutting that was first grown in a container and, seven years later, was in the ground and beginning to flower and fruit. The description provides no exact measurements, fruit observations, or timestamped details. The video page shows a relative upload age only, so no publication date is assigned.

Summary from transcript: Charles Malki, identified as a biologist and plant expert, cuts a Mexican lime at 8:30–9:10 and notes a couple of small seeds. This is an observation of the shown fruit, not a sample-wide seed count or measured fruit description. English auto-generated captions cover 0:00–17:09 of 17:17.

Summary from transcript: The presenter identifies one thorned and one thornless Key lime in a four-fruit comparison. He reports seeds in both Key lime samples at 9:36. At 13:37–13:50, he says the thornless fruit seemed a little more bitter than the thorned one but allows that it may have been greener; this is a subjective comparison of two individual fruits, not a bitterness score or cultivar-wide difference. Spoken setting/date only; no verified upload date. English auto-generated captions cover 0:07–15:22 of 15:29.

Table 1 lists Mexican lime (Citrus aurantifolia) as diploid, IVIA-164. Figure 3D–E and the Results describe pollen-nuclei populations denoted 1V/1G and 2V/2G; the Discussion confirms unreduced pollen in this diploid Mexican lime genotype. The reported 2V/2G population supports the unreduced-pollen finding; a 4G population is not established as a proven unreduced pollen class. This study does not establish whole-plant tetraploidy, pollen fertility, or cross-success rates.
