With the massive variability in effects, I’ve always been curious about how cannabis strain lineages relate between the strains I prefer. So I built the lineage chart I couldn’t find elsewhere.
WeedTree is a work in progress, compiled from many international sources, which often disagree. I have also made practical simplifications around cultivars, phenotypes, clones, variants, renaming, and disputed pedigrees so the information can be represented as a navigable family tree. The chart is therefore likely to contain errors and remains far from complete.
Ancestor contribution percentages are calculated from the relationships recorded in the chart. Where explicit parent weightings are provided, those weightings are used; otherwise recorded parents are treated as equal contributors. They are useful for exploring lineage, but they should not be interpreted as measured genetic composition. They cannot account for selective breeding, gene expression, phenotype selection, backcrossing, or inaccuracies in the underlying pedigree information.
