Parentage not published by the breeder. No single parent pair is established for this catalog entry. Areto does not estimate parents it has no report of.
Academic research: Canna Tsu, a CBDA-dominant chemotype III cultivar, has been reported to have lowly expressed fragments similar to "inactive THCA" synthases. (2021; citation)
Academic research: A sesquiterpene synthase gene from Canna Tsu (CsTPS20CT) was characterized as a hedycaryol synthase. (2025; citation)

Peer-reviewed, open-access studies that examined samples sold or grown under this name. Findings describe those samples, not the breeder’s release, and may not match every product. Each quote is copied from the paper’s full text.
- Cannabinoids: Citing a prior study, the paper reports that CBD/CBDA were mostly below 1% in the listed varieties except Canna Tsu, which was higher.
“the CBD and CBDA concentrations in the above varieties were very low, mostly below 1% with the exception of Canna Tsu [34]”

“lowly expressed fragments from CBDA-dominant (chemotype III) cultivars such “Carmen” and “Canna Tsu” have been reported to be similar to those “inactive THCA” synthases”

Areto Research estimateNot published by the breeder. Areto Research estimated this from the strain’s name, reported parentage and commonly described traits; it is not a source, a lab result or a prediction for any product. Details marked “general guess” have low confidence. Each estimate is replaced as soon as a breeder publishes that detail.
Source access date not recorded. Fields without supporting records remain unknown. Potency and terpene composition vary by product batch; use that batch’s COA for tested values. View sources.
Indica, sativa and hybrid are retail shopping labels, not genetics. Parentage is breeder-reported and not DNA-verified. Use your product’s batch COA for tested potency. How Areto sources this page.

Cultivar facts come directly from the cited breeders. A breeder’s description is a reported claim, not independent genetic verification or a test of your product batch. Community members’ personal experiences are separate from these facts. Corrections: genetics@areto.tech.
