'''Ban Nan Toeng General Population 2025''' is a general population domesticate landrace accession documented in [[Thailand]] by [[User:Eloise Zomia|Eloise]] and [[User:Izazomia|Isabella]]. Seeds were sourced from the Nan Toeng Village Community in [[Ban Nan Toeng]], within the [[Phu Phan Mountains]] of [[Sakhon Nakhon Province]]. This accession represents the broad Lao-Isan landrace population cultivated using traditional [[open-pollination]] methods.

== Geography ==
== Geography ==


This accession originates from the [[Phu Phan Mountains]] in [[Sakhon Nakhon Province]], in [[Isan]], [[Thailand]]. [[Ban Nan Toeng]] lies on the edge of the [[Kut Bak plateau]] at 200 meters elevation. The region experiences a monsoonal growing cycle with dry-season harvests.
[[Ban Nan Toeng]] is situated on the edge of the [[Kut Bak plateau]] within the [[Phu Phan Mountains]] of [[Sakhon Nakhon Province]], in the [[Isan]] region of northeastern [[Thailand]]. The village sits at approximately 200 meters elevation in a warm, dry upland climate that has historically supported cannabis cultivation for generations. The Phu Phan Mountains were a significant source of material for the historic [[Thai Stick]] trade during the 20th century.


== Collection Details ==
== Collection Details ==


Seeds were collected in 2024 from the standing general population grown by the Nan Toeng Village Community. Collection reflects the full genetic spectrum present in the field, maintained through direct seeding and traditional [[open-pollination]] practices.
This accession represents the unselected general population of the Ban Nan Toeng landrace, collected in November 2024 by [[User:Eloise Zomia|Éloïse]] and [[User:Izazomia|Isabella]] from the Nan Toeng Village Community during expedition ISAN02. Seeds were sourced directly from locally grown plants, reflecting the full phenotypic diversity of the population.


Population size in the region is estimated at approximately 10,000 plants during peak season.
== Cultivation Details ==
 
Cannabis is cultivated outdoors using direct seeding on upland village plots. Planting takes place between July and September, with harvest occurring between January and March. Plants typically reach between 2 and 3 meters in height. Seed stock is maintained entirely on-farm by the local community.


== Botanical Characteristics ==
== Botanical Characteristics ==


Plants display classic Lao-Isan narrow-leaf morphology with tall, elegant structure and long internodal spacing. Heights range between 2–3 meters. Flowering occurs under short-day conditions.
The Ban Nan Toeng general population displays classic narrow-leafed Lao-Isan morphology, with tall, elegant Christmas tree growth, long internodal spacing, and 9-leaflet narrow leaves. Two primary phenotypic expressions are present within the population. The Tiger Tail (Hang Suea) phenotype is characterised by robust structure, thicker colas, strong lateral branching, and a dense trichome coating, with an earthy, spiced terpene profile. The Squirrel Tail (Hang Krarok) phenotype is more delicate and elongated, producing cascading foxtail-like colas and lighter flowers, with a sweeter, more tropical aroma profile dominated by mango and floral notes.


Two primary phenotypic expressions are present within the population:
== Aroma ==


Tiger Tail (Hang Suea): Dense, robust structure with strong lateral branching and heavy resin production.
The overall terpene spectrum of the population ranges from earthy spice, herbal musk, and woody undertones through to bright sweet fruit, mango, and tropical floral notes.


Squirrel Tail (Hang Krarok): Elongated, Foxtailed expressions with lighter, more Airy flower development.
== Effects ==


Flower Structure across the broader population ranges from Loose to Foxtailed depending on phenotype.
Effects are clean, clear-headed, and stimulating, with an uplifting and euphoric quality. The high is long-lasting and notably paranoia-free, consistent with classic Mekong sativa expression.


The terpene spectrum spans earthy spice, herbal musk, woody undertones, and bright sweet tropical fruit notes including mango. Effects are described as clean, stimulating, long-lasting, and culturally valued for both recreational and medicinal use.
== Conservation Status ==
 
== Cultivation Details ==


Regional Planting: July - September
The Ban Nan Toeng landrace faces ongoing genetic pressure from the widespread culling of male plants, driven by a shift toward seedless flower production. This practice has created a genetic bottleneck, with hermaphroditic plants becoming an increasingly dominant pollen source. Conservation efforts are underway, with plans to cultivate large male populations in controlled remote settings to restore genetic diversity and produce stabilised seed stock for local farmers.

Plants are grown outdoors through direct seeding, with seeds produced via traditional [[open-pollination]].
 
== Conservation Status ==
 
The population remains active and viable; however, increased male culling and a shift toward seedless flower production are creating genetic bottlenecks. A conservation breeding initiative is planned to reintroduce a larger male population and stabilize seed stock for long-term resilience.

Ban Nan Toeng General Population 2025 is an open-pollinated domesticate landrace cannabis accession representing the full genetic breadth of the Ban Nan Toeng population, cultivated in the Phu Phan Mountains of Sakhon Nakhon Province, northeastern Thailand. The accession was documented by Éloïse and Isabella during expedition ISAN02 in November 2024.

Geography

Ban Nan Toeng is situated on the edge of the Kut Bak plateau within the Phu Phan Mountains of Sakhon Nakhon Province, in the Isan region of northeastern Thailand. The village sits at approximately 200 meters elevation in a warm, dry upland climate that has historically supported cannabis cultivation for generations. The Phu Phan Mountains were a significant source of material for the historic Thai Stick trade during the 20th century.

Collection Details

This accession represents the unselected general population of the Ban Nan Toeng landrace, collected in November 2024 by Éloïse and Isabella from the Nan Toeng Village Community during expedition ISAN02. Seeds were sourced directly from locally grown plants, reflecting the full phenotypic diversity of the population.

Cultivation Details

Cannabis is cultivated outdoors using direct seeding on upland village plots. Planting takes place between July and September, with harvest occurring between January and March. Plants typically reach between 2 and 3 meters in height. Seed stock is maintained entirely on-farm by the local community.

Botanical Characteristics

The Ban Nan Toeng general population displays classic narrow-leafed Lao-Isan morphology, with tall, elegant Christmas tree growth, long internodal spacing, and 9-leaflet narrow leaves. Two primary phenotypic expressions are present within the population. The Tiger Tail (Hang Suea) phenotype is characterised by robust structure, thicker colas, strong lateral branching, and a dense trichome coating, with an earthy, spiced terpene profile. The Squirrel Tail (Hang Krarok) phenotype is more delicate and elongated, producing cascading foxtail-like colas and lighter flowers, with a sweeter, more tropical aroma profile dominated by mango and floral notes.

Aroma

The overall terpene spectrum of the population ranges from earthy spice, herbal musk, and woody undertones through to bright sweet fruit, mango, and tropical floral notes.

Effects

Effects are clean, clear-headed, and stimulating, with an uplifting and euphoric quality. The high is long-lasting and notably paranoia-free, consistent with classic Mekong sativa expression.

Conservation Status

The Ban Nan Toeng landrace faces ongoing genetic pressure from the widespread culling of male plants, driven by a shift toward seedless flower production. This practice has created a genetic bottleneck, with hermaphroditic plants becoming an increasingly dominant pollen source. Conservation efforts are underway, with plans to cultivate large male populations in controlled remote settings to restore genetic diversity and produce stabilised seed stock for local farmers.
