Evidentiary scope

The article rests on the RSC listing for Iranian, the Kwik Seeds listing of the same line and two RSC blog posts ("New Hindu Kush and Iranian landrace accessions", October 2019; "Iranian and Syrian Landraces Back In Stock", July 2022). Kwik Seeds is the shop RSC calls its other site (RSC, Hemp & Multipurpose). The listings place the collection in the Khorasan region of northeastern Iran in 2019 and name no province, village or farmer. RSC credits the sourcing to Kushman, a collector its 2019 post describes without further identification. The seed now on sale is an open-pollinated reproduction of that collection. The account of Qutb ad-Din Haydar and the Haydaris is RSC's and has not been checked against other sources; the article attributes it. The conservation priority is Medium; the basis is below.

Georeferencing

The listings give only "the Khorasan region of northeastern Iran" and a latitude of 35° N. Khorasan is not a single province: OpenStreetMap maps Razavi Khorasan, North Khorasan and South Khorasan provinces. So that the accession appears on the map, the coordinate is inferred as the middle of the three provinces' combined extent along 35° N in OpenStreetMap (relations 537657, 225444 and 537658, full polygons; 56.45° E to 61.11° E), rounded to two decimal places: 35.00, 58.78. OpenStreetMap places that point in Mahvelat County, Razavi Khorasan Province. It is an inference from the listings, not a collection site, so the province field stays blank and the region code is UNK. Éloise 13:42, 17 September 2026 (+07)

Editorial treatment

Accession ID. RSC-IRN-UNK-0120190001: UNK because the listings name a region, not a province; the year is that of the collection. The month digits are 01 because no month is given.
Name. Iranian Reproduction 2019, because the seed on sale is a reproduction of the 2019 collection, as on Highland Thai Reproduction 2008.
Reproduction. "An open-pollinated reproduction of the 2019 accession" is entered as accession type Reproduction, pollination type Open pollination and autochtonous No. No sourcing type is entered, because the listing does not say how many generations have been grown.
Collector. Left blank. The listing credits Kushman, and the convention enters Angus only for RSC's own sourcing lines.
Purposes. "Charas (sieved resin), bhang" is entered as purpose Recreation and processing method Dry-sift, as on the Hispar and Hopar accessions.
Photoperiod. Semi-autoflowering. Kwik Seeds files all three Iranian lines under Auto & Semi-Auto, a category for autoflowering and semi-autoflowering strains, and RSC's August 2025 post "Auto and Semi-Auto Traits in Landrace and Feral Cannabis" names only 'Selected Siberian' and 'Kazakh' as the pure auto varieties in its collection. Neither listing's text states the photoperiod.
Introgression. Unknown, because RSC's July 2022 post says it cannot be entirely sure the line is pristine. The other RSC accessions use Minimal.
Harvest. Mid-September to October, RSC's current range, which contains Kwik Seeds' late September to October.
Seed viability. Not entered. RSC now reports testing below 80 per cent; Kwik Seeds, and RSC from August 2020 to October 2025, reported close to 100 per cent (see below).
Links. Khorasan is linked as a region; its page type is Éloïse's call. Qutb ad-Din Haydar is linked as a person without the diacritic, which the displayed name keeps. Turkmenistan and the Near East are left unlinked. Éloise 13:42, 17 September 2026 (+07)

Conservation priority

Medium. RSC says "seeds are direct from local farmers" in Khorasan, which its post of 28 July 2022 calls a very ancient centre of cannabis culture. 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

Sourcing. RSC: "Kushman – Khorasan, Iran (2019)". Kwik Seeds: "The Real Seed Company, Khorasan, Iran, 2019 Harvest", RSC's own line from August 2020 to December 2022 (below).
Genetics line. RSC: "Iranian Cannabis Landrace". Kwik Seeds: "Iranian Domesticate (“Landrace”)", RSC's line from April 2021 to March 2023.
Purpose. RSC adds bhang. Kwik Seeds gives charas only, as RSC did until December 2022.
Harvest. RSC: "mid-September to October". Kwik Seeds: "late-September to October", RSC's wording until September 2025.
Viability. RSC: "reduced price because of testing below 80% viability". Kwik Seeds: "close to 100% germination".
Description. Kwik Seeds calls the line "a very high-yielding landrace with immense flower production", RSC's 2019 wording, and keeps "Most famously" before the Haydar sentence, as RSC did until October 2023. Only RSC compares Iranian landraces with those of the Hindu Kush and Near East.

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 23 versions of the RSC listing, from October 2019 to April 2026, and all were read. All give the 2019 collection in Khorasan.

Seed on sale. From August 2020 to May 2022 the listing called the seed "a new accession from the 2019 harvest"; from August 2022 it calls it "an open-pollinated reproduction of the 2019 accession". Both describe the same collection, so the article uses both.
Sourcing. "Personally collected at source in Khorasan, Iran" in October and November 2019; "The Real Seed Company, Khorasan, Iran, 2019 Harvest" from August 2020 to December 2022; "Kushman, Khorasan, Iran, 2019 Harvest" from March 2023 to March 2025; the current line from July 2025. The article cites the version of 22 October 2019.
Classification. "C. sativa subsp. indica var. afghanica x C. sativa subsp. indica var. indica" from August 2020 to May 2024, with "Cannabis" written out from October 2023. The article cites the versions of 5 August 2020 and 25 May 2024.
Height and aroma. "[forthcoming]" until October 2021; the current values from May 2022.
Viability. "Close to 100% germination" from August 2020 to October 2025; "testing below 80% viability" from January 2026.
Dropped text. The 2019 versions carried two images of 16th-century Turkish qalandars, with the statement that qalandars "are believed to have been responsible for bringing sacramental chronic cannabis use from Central Asia and eastern Iran to the Middle East, North Africa, Asia Minor, and the Balkans in the 13th century". It is RSC's historical claim, not a detail of the collection, and is not used. 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. The listing gives them no captions. RSC's July 2022 blog post uses the infobox photograph as its own image and says it shows "the Iranian outdoors in North America", so its caption gives that place with the post's date. The other four have no caption from RSC, so their captions say only what each image shows. RSC masked part of the background in one field photograph. The August 2022 version of the listing (Wayback Machine) shows three of the five, including the infobox photograph; the October 2019 version showed a different photograph.

Collection and reproduction split

This page is the 2019 collection in Khorasan. The seed RSC sells under the same listing is an open-pollinated reproduction of it and is now a separate accession, 2019 RSC Iranian Reproduction, under the rule that the plain ID stays with the collection and a reproduction takes a -R1 suffix.

The listing dates the change itself. Versions from 5 August 2020 to 20 May 2022 read "This is a new accession from the 2019 harvest"; from 18 August 2022 they read "This is an open-pollinated reproduction of the 2019 accession". Both describe the same collection, so the material this page describes was on sale until at least May 2022.

What stayed here: the geography, the history, the sourcing line and the botanical description, which the listing gives for the landrace, and the photographs, which RSC's July 2022 post places outdoors in North America without naming a lot. What moved: the reproduction, its viability figures and RSC's statement that it cannot be entirely sure the line is pristine. Accession type is now General population, sourcing Point of Origin, autochtonous Yes; pollination type is blank, because open pollination describes the reproduction and not the field the seed was collected from.
