Deogaon General Population #3 2025 is a domesticate landrace cannabis accession. This accession was documented by Isabella & Éloïse in June 2025. A total of 28 seeds were given to Éloïse by a local cannabis grower. The seeds come from a cultivated landrace cannabis population of 100+ plants grown near Deogaon. Deogaon is located in Alipurduar District, West Bengal, India, within the Khairbari-Deogaon landrace cannabis growing area of The Dooars growing region.

Chromosomal sex is set by X and Y chromosomes, while sex expression can be shifted by the environment.
}}Dioecy is the condition in which male and female flowers are borne on separate individuals, so that any one plant is either pollen-bearing (staminate) or seed-bearing (pistillate). Cannabis is normally dioecious: a crop raised from seed separates into male and female plants in roughly equal numbers. The two sexes differ in the structure of their flowers and, less sharply, in growth habit. Dioecy is the ancestral and prevailing condition in the family Cannabaceae, shared with the sister genus Humulus, the hops; a minority of cultivated hemp lines are instead monoecious, carrying both kinds of flower on one plant.
The separation of the sexes shapes how cannabis is grown and how its populations are structured. Because cannabinoids accumulate mainly in the resin of the unfertilised female inflorescence, drug-type and cannabinoid crops are grown as female-only stands. Excluding pollen is central to their cultivation, since a pollinated inflorescence sets seed in place of resin. … read more →

Cannabis eradications
We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge, preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.
