Lineage Basics

Why reported lineage can vary between seed banks

The same strain name doesn't always mean the same plant. Here's why.

3 min read2026-05-2916 views

If you've bought seeds long enough, you've noticed the same strain name can show up at different seed banks with different listed lineage. It's not always dishonesty. Cannabis genetics history is messy — undocumented crosses, lost notes, multiple cuts circulating under one name, breeder turnover — all contribute to the same name representing different actual genetics across the market.

The five main reasons lineage diverges

1
Multiple cuts circulating under one name
GG#4 (Original Glue) has multiple cuts. Wedding Cake has several different mothers. Each cut has different real lineage despite sharing the name.
2
Lost documentation
Many strains were created in eras when no formal record-keeping existed. Best-guess lineage is reconstructed years later.
3
Breeder marketing renaming
Seed banks sometimes rebrand existing crosses with new names. The 'original' parents are obscured.
4
Open pollination ambiguity
In landrace and preservation breeding, multiple males may pollinate the seed batch. Reported parentage is approximate.
5
Honest disagreement
Two credible breeders genuinely disagree on parentage. Without DNA testing (which is rare and limited), there's no perfect arbiter.

How CannaForge handles this

We don't pick a winner. When parentage is contested, the strain page shows both (or all) credible readings, labeled as disputed. Hiding the disagreement would erase real information — the disagreement itself is data.

Real examples of name-level divergence

Wedding Cake — multiple cuts (TK cut, Jungle Boys cut, etc.) with different reported lineage but shared name.
OG Kush — at least three major cut lineages (Tahoe, SFV, Ghost) all called "OG Kush".
Gelato — many named numbered phenos (Gelato #33, #45) plus multiple S1 lines.
GMO (Garlic Cookies) — well-documented now, but had years of inconsistent attribution.
GG#4 — multiple cuts and S1 lines, mostly traceable to the original.

How seed banks compound the problem

Marketing rewrites: Banks rewrite breeder copy and lose nuance.
Multi-source listings: A bank stocks multiple breeders' takes on the same name.
Translated catalogs: International seed banks translate breeder notes and sometimes change meanings.
Reseller noise: Strain names get attached to packs by resellers who didn't make the cross.

What you can do as a collector

1
Source directly from the breeder when possible
Closer to the source = clearer lineage.
2
Read the breeder's own description
Not the seed bank's marketing copy.
3
Check CannaForge's lineage state
Verified, reported, or disputed — each tells you something.
4
Save your pack photos and breeder notes
Your own records become future verification.
5
Don't assume name = identity
If you're paying a premium, you're paying for the documented version.

Common mistakes

Assuming a famous name guarantees famous genetics.
Treating reseller listings as authoritative.
Discarding 'disputed' strains — they may be the same plant your favorite breeder is also working with.
Buying based on marketing copy that obscures real parentage.

Should I avoid disputed lineage strains?+

No — they're often the most interesting genetics. Just know what you're buying.

Will DNA testing ever resolve this?+

It can help, but cannabis DNA is poorly mapped compared to commercial crops, and testing is expensive. For now, breeder records + community attribution are the working method.

What if I find a new lineage discrepancy?+

Submit a correction on the strain page. CannaForge tracks reports and re-checks with breeders.
