Every entry here is traced back through breeder records, catalog history, and partner-verified lineage — not guesswork. Where attribution is disputed, we say so instead of papering over it.
Context for everything else on this site — where hemp's genetic diversity came from, and why so much of it has already been lost.
Hemp was domesticated in Central Asia and spread along early trade routes into China, India, and eventually Africa and Europe. Regional growing conditions over thousands of years produced distinct landraces — genetically stable populations adapted to their specific climate and use, whether fiber, seed oil, or grain.
Hemp was a staple fiber crop in colonial America, grown widely for rope, canvas, and textiles. Seed stock moved with settlers and traders, mixing landraces and creating regional strains whose exact genetic makeup was rarely recorded.
The Marihuana Tax Act of 1937, and federal scheduling that followed, effectively ended commercial hemp cultivation in the U.S. Seed banks, breeding programs, and generations of institutional growing knowledge went dormant or disappeared entirely. This is the biggest single gap in the historical record we're working to document.
The 2014 Farm Bill authorized pilot hemp research programs, and the 2018 Farm Bill federally legalized hemp cultivation (defined as cannabis with 0.3% or less delta-9 THC by dry weight). Breeders and farms began rebuilding seed stock — some from surviving landrace lines, some from crosses developed during prohibition.
A patchwork of small breeders, archivists, and collector-focused seed banks are now the primary keepers of hemp genetic diversity — mostly working independently, with no shared registry. That's the gap 143 Genetics is built to fill.
Our founding partner's full catalog traces back to two backbone crosses. This is the first fully-mapped lineage in the 143 Genetics archive.
An in-house purple line developed by Chef Budz Genetix and reversed onto 26 catalog releases. Functions as one of two founding hubs the rest of the catalog crosses back into.
A landrace-descended cross — Acapulco Gold × Colombian Gold, dating to the 1970s — used as breeding stock for 11 gold-toned, citrus-leaning releases in the catalog.

Full node-by-node lineage graph lives on our partner's own archive. We'll be building a unified, cross-partner lineage map here as more breeders join the registry.
A lot of "genetics" content online is marketing dressed up as science. Here's our actual methodology.
Lineage claims start with the breeder or farm's own catalog history, cross records, and reversal logs — the same records they use internally.
When parentage is contested or unconfirmed, we say so directly instead of presenting it as settled fact. A disputed line is still useful history — it just needs a label.
We're not going to invent pseudo-scientific terminology to sound more credible. If we can't cite it plainly, we don't publish it as fact.
If you're a breeder or farm with documented (or even partially documented) hemp genetics, we want to help archive it before that history is lost.
