Everything in the cannabis game is a polyhybrid, which is a fucking meaningless distinction anyway, when talking about subspecies, aka “varieties” in the botany taxonomy scene.
indica and
sativa are varieties of
Cannabis sativa. None of which has anything to do with “stability”
New concepts are reviewed in Cannabis systematics, including phylogenetics and nomenclature. The family Cannabaceae now includes Cannabis, Humulus, and eight genera formerly in the Celtidaceae. Grouping Cannabis, Humulus, and Celtis actually goes back ...

Cannabis plants naturally and regularly throw opposite sex flower structures, often as a response to stress. Some cultivars more than others, but it has nothing to do with “hybrids” or “polyhybrids” or “indica” or “sativa” - we growers use those words incorrectly almost without exception.
Please read the paper I linked and look at the map. Most phylogenetic systematists consider it a single species that has subspecies only as a result of cultural traditions based in misunderstandings. I am deeply skeptical of anyone claiming to have true land race strains, those landraces that currently exist were almost doubtlessly selectively bred and outcrossed by humans up to a couple thousand years ago. It is true, and mentioned in the paper that cannabis reverts to a ‘feral’ state after about fifty generations, but that doesn’t mean it’s genotype is pure landrace.
Making decisions based on a bad pseudoscience and having strong opinions about what’s desirable as a result of that misunderstanding is a dangerous road that leads to more uneducated pontification about the evils of polyhybrids or feminized seeds or whatever the fuck.
If we are going to continue to use the terms Indica and Sativa it should be a reference to chemotype, sativa has CBD dominant over THC and indica has THC dominant over CBD. Then the only ‘hybrids’ could be considered the 1:1 ratio THC:CBD expression. That’s how scientists first meant those words, though even that is not true. Hundreds of years ago they had collected some ’sativas’ that had the THC dominant (drug effect they called it) expression and vice versa for indica.
My view, supported by the latest and best scientific research and opinions that I can find, is that Cannabis is a single species, Cannabis sativa, with subspecies appellations
indica and
sativa capriciously applied to indicate morphological differences. I know someone will probably mention
C. ruderalis in their response, which is addressed in the paper, and is probably best classified as
Cannabis sativa subsp. ruderalis.
Educate yourself, and free your mind. Buy stuff from reputable breeders and carry on. If you are throwing a lot of herms from different sources then it is probably your grow environment or practices and not the genetics.
