Discussion

Evidentiary scope

The article rests on the RSC listing for Kazakh Ruderalis, the Kwik Seeds listing of the same line, RSC's Crop Wild Relatives and CBD category pages and four RSC blog posts (October 2019, November 2023, January 2025 and August 2025). Kwik Seeds is the shop RSC calls its other site (RSC, Hemp & Multipurpose). The listings place the collection in the southern Qarataū, credit a "Russian Landrace Bureau in Jambyl" and date it to 2019; they name no site or collector. The seed on sale comes from a 2023 ex situ maintenance grow. The November 2023 post places the line in "the mountains of eastern Kazakhstan"; the listings and the October 2019 post name Jambyl and the Qarataū. The history of cannabis in Central Asia and the centre-of-origin claims are RSC's; they are not corroborated by another source, and the article attributes them. The conservation priority is Medium; the basis is below. Éloise 13:42, 17 September 2026 (+07)

Georeferencing

The listings name Jambyl, the northwestern Tien Shan and the southern Qarataū, and give a latitude of 44° N. OpenStreetMap maps the Karatau range only as a single point (node 5555922221, at 43.80, 68.67), which lies in Turkistan Region, not in Jambyl, so the range is not used. The coordinate is the label point of Jambyl Region (relation 215722, label node 974358688), rounded to two decimal places: 44.42, 72.13, in Moiynkum District. It marks the region the sourcing line names, not the collection site, which the listings place in the Qarataū further west. Éloise 13:42, 17 September 2026 (+07)

Editorial treatment

Accession ID. RSC-KAZ-JAM-0120190001 takes JAM from Jambyl Region. The month digits are 01.
Province. Jambyl Region, the English form OpenStreetMap uses, with the suffix used for Madagascar's regions (Diana Region).
Name. Kazakh Ruderalis Feral Reproduction 2019, following Humla Jungli Feral Reproduction 2021.
Classification. Feral, from RSC's "wild-type", Kwik Seeds' "feral or weedy rather than truly wild" and RSC's August 2025 "feral forms". Cultivation system type Feral describes the source stands. The lead does not call the accession a landrace, because RSC's November 2023 post says wild-type strains such as this one are not domesticates.
Reproduction. Accession type Reproduction and autochtonous No, because the seed comes from a 2023 ex situ maintenance grow. No sourcing type is entered.
Collector. Left blank. The listings credit a "Russian Landrace Bureau", which they do not identify further.
Photoperiod. Day-neutral, stated in both listings and in RSC's August 2025 post; it is not the corpus convention. RSC's listing reads "very early maturing to day-neutral".
Introgression. Unknown, because RSC says drug-type and fibre-type domesticates have been introduced extensively in Kazakhstan, and its 2023 post says the population has almost certainly exchanged genes with landraces.
Purpose. "n/a" is entered as primary purpose and processing method N/A.
Height. 2 to 5 m, from the versions of November 2019 to May 2025; the current listing says only that plants "can exceed 4 meters".
Vocabulary mapping. "Heavily branched" is entered as Extensive, "leaflets are predominantly narrow" as Narrow and "large colas" as flower structure Big.
Links. The Tien Shan links to the conventional title Tian Shan, and the Qarataū to Karatau Mountains. Uzbekistan, Kyrgyzstan, Tibet, the Qinghai Plateau and the Eurasian Steppe are left unlinked. Éloise 13:42, 17 September 2026 (+07)

Conservation priority

Medium. RSC describes a wild-type population of the Qarataū, a broad region of eastern Central Asia where it says cannabis is well adapted and where millennia of cultivation have affected any truly wild populations. Neither listing states rarity. RSC states no conservation priority of its own, so the rating is the wiki's, on the four values it uses for accessions: Critical, High, Medium and Low. Éloise 21:05, 17 September 2026 (+07)

Source discrepancies

Genetics line. RSC: "Wild-type Kazakh Cannabis". Kwik Seeds: "Ruderal Kazakh Cannabis".
Characteristics. RSC: "Very early maturing to day-neutral". Kwik Seeds: "Very early maturing, day-neutral", RSC's November 2019 wording.
Height. RSC has no height line; Kwik Seeds: "Variable". RSC gave "2 –5 meters" until May 2025.
Divergence from Humulus. RSC: "some 28 million years ago". Kwik Seeds: "some 30 million years ago".
Place. The listings and the October 2019 post: Jambyl and the southern Qarataū. The November 2023 post: "the mountains of eastern Kazakhstan".
Only on Kwik Seeds. The feral-or-weedy characterisation, the Crop Wild Relative paragraph naming Siberian Ruderalis and the "signs of domestication".
Only on RSC. The paragraphs on early domestication, archaeological evidence and the subspecies indica, and on classification.

The listings do not explain the differences. The article uses both and attributes each. Éloise 13:42, 17 September 2026 (+07)

Archived versions

The Wayback Machine holds 19 versions of the RSC listing, from November 2019 to February 2026. All give the 2019 collection from Jambyl.

November 2019. Genetics "Pure Kazakh landrace, intermediate domestication"; "A pure Kazakh landrace collected in the northwestern Tien Shan range"; "This accession is best classified as ruderal i.e., ssp. indica var. kafiristanica". The article cites this version, of 18 November 2019.
Classification. "C. sativa subsp. sativa var. spontanea x C. sativa subsp. indica [?]" from August 2020 to April 2021, and without the question mark from September 2021 to January 2023. The article cites the versions of 5 August 2020 and 30 January 2023.
Height. "2 –5 meters" from November 2019 to May 2025. The article cites the version of 20 May 2025.
Seed on sale. "New 2023 seeds" from April 2024, "from an ex-situ maintenance grow" from February 2025.
Colas. "Denser than those of truly weedy ruderal Cannabis" in November 2019, "denser than those of wild-type Cannabis" from August 2020 to September 2021 and the current wording from November 2021.
The November 2019 and August 2020 versions showed a different image, filed as "Karatau". Éloise 13:42, 17 September 2026 (+07)

Photographs

The infobox image and the gallery are the five photographs on the RSC listing, uploaded under fair use at reduced resolution. RSC's August 2025 post uses a file byte-identical to the infobox photograph and says it shows "the Kazakh outdoors around 55° N", so its caption gives that latitude with the post's date. The other four have no caption from RSC, so their captions say only what each image shows. Kwik Seeds shows a byte-identical copy of one of them. Éloise 13:42, 17 September 2026 (+07)

Collection and reproduction split

This page is the 2023 ex situ maintenance grow that RSC now sells. The collection it was grown from was made in Jambyl in 2019 by the Russian Landrace Bureau and is now Kazakh Ruderalis General Population 2019, under the holder code RLB.

The listing dates the change. From the earliest archived version, of 18 November 2019, RSC sold seed of the 2019 collection; "New 2023 seeds" first appears on 17 April 2024 and "from an ex-situ maintenance grow" on 8 February 2025. So the material this page describes has been on sale since about 2024, and the collection's own seed was on sale before it.

No suffix was needed on this page's ID. A reproduction takes -R1 only where it would otherwise collide with its parent, and here the holder codes differ.

The coordinates moved to the collection, so the population holds one point on the map. sample_harvest_date is now 2023, the year of the grow; collection_date stays 2019, the year the population was sampled. Éloise 04:02, 18 September 2026 (+07)

Descriptive name

The descriptive name now leads with the year and the holder's acronym: 2019 RSC Kazakh Ruderalis Feral Reproduction, where it read Kazakh Ruderalis Feral Reproduction 2019. A reproduction's descriptive name carries the year first and names the reproducer, and this is applied to every reproduction in this corpus.

The acronym is the holder's, the same code the accession ID carries. It does not assert who conducted the grow-out: these listings name nobody, and the rule was given for a line whose reproducer the listing does not state either.

The page title is the accession ID and is unchanged, so no link breaks. Earlier entries on this page that quote the old name are left as they were written: they record what was decided then. Éloise 05:18, 18 September 2026 (+07)

USDA genebank accession

The U.S. National Plant Germplasm System holds this seed as G 33875 (GRIN-Global entry), received on 25 July 2024 in a donation from Angus. The infobox lists it as the same lot as this accession:

the donor narrative on the entry repeats the listing's own words, "New 2023 seeds from an ex-situ maintenance grow", and names Jambyl;
this page is that 2023 maintenance grow: the listing first offers "New 2023 seeds" in April 2024, three months before the donation of 25 July 2024;
the collection it was grown from is RLB-KAZ-JAM-0120190001, whose own seed RSC sold before 2024.

The entry's collector field is not used as evidence: GRIN enters Angus as collector on most accessions of his donations, including lines whose narratives name another collector or none. Éloise 06:29, 4 October 2026 (+07)
