Landrace and heirloom-heritage cannabis strains

Landrace cannabis refers to the regional populations that adapted over centuries to specific climates and latitudes before modern breeding consolidated genetics into the indica, sativa, and hybrid categories used today. The list below scores library entries whose documented parent strains include known landrace lines — Afghani, Thai, Colombian, Mexican, Indian, Hawaiian, Hindu Kush, Durban Poison, Brazilian, and Pakistani heritage — with a smaller bonus for strains whose recorded family explicitly tags pure indica or landrace classification. Landrace genetics are documented as carrying narrower THC ceilings than modern hybrids but broader terpene complexity, higher pest and pathogen resistance, and the original phenotype expressions from which the entire modern catalogue was bred. None of these are guaranteed pure landrace — most are landrace-leaning hybrids preserving heritage genetics in a more growable package. The ranking is descriptive, drawn from the lineage and family data recorded in each entry's catalogue.
