Absolutely! Afghani-dom strains tend to be magnets for it, which makes sense. How much PM is there/are they observed/experienced/exposed to in the mountains of Afghanistan? Vietnam? Cambodia? Thailand? India highlands vs the south part of the subcontinent?Do you think it is the lineage from parts of the globe that are damper. For example, Thai genetics might lend a resistance to powdery mildew. Super Skunk is very PM resistant, and I think the smelly volatile oils may play a part. For that strain perhaps the Columbian lineage plays a role in PM resistance, or maybe not...
Lol funny cause i hade a black rose hybrid that would be the only one to show pm out of 12. im making a case here lol.I've gotten it before and sannies seeds jackberry resisted it but yet my black rose loved pm. They was side by side in the room.
The best way to breed any resistances is to take a pheno run, take marked clones of everything, and do not ventilate properly... make stale aged air... add humidity... now watch the pheno run for an individual that lasts the longest without getting PM and use that plant for your next F-gen... rinse and repeat... by using only the plants that either do not get PM, or that last the longest without damage out of a seed group when these stale moist conditions are applied, you are effectively breeding for PM resistance. Replace stale moist air with introducing spider mites... find which plant is clear when others are all webbed up... the cleanest one is the most resistant... add any other pathogen or pest you can imagine and the last plant to die should have its clone used in the next generation.
And yeah... I said to purposefully cause your own infestations...
now you see why most breeders do not breed for resistances much, if at all.
The pure narrow leaved drug strains I've personally collected from Thailand and Cambodia were definitely not powdery mildew resistant. I would actually say they are susceptible. The same sorts of PM infect mangos and cashews in the equatorial areas. If anything the high temperatures and intense sunlight help keep the fungus at bay. Once the plants are away from that environment they seem to lack any inherent defenses to it.Absolutely! Afghani-dom strains tend to be magnets for it, which makes sense.

I don't know that the terpenes play a role, but it would make some sense. I think it's as much to do with the plant's immune response system as anything else, though.
Interesting. Susceptible to the point of killing the plant? I can't say I've grown any pure Satties to this point, just smoked 'em. But, I'd love to give 'em a try.The pure narrow leaved drug strains I've personally collected from Thailand and Cambodia were definitely not powdery mildew resistant.

PM can thrive in high temp low RH. Downy mildew is the stagnant wet hot air shit in my experience.Interesting. Susceptible to the point of killing the plant? I can't say I've grown any pure Satties to this point, just smoked 'em. But, I'd love to give 'em a try.
PM was bad for the bull thistle this year. Such low RH and high temps I wouldn't have thought, but there it was.
Durban poison. Colombian.An aside... As far as extracting terpenes, you can use steam distillation. https://en.wikipedia.org/wiki/Cannabis_flower_essential_oil
Hmm, perhaps Limonene helps, it says it can help medically. http://www.leafly.com/knowledge-center/cannabis-101/terpenes-the-flavors-of-cannabis-aromatherapy
Now selective breeding of which land race strains might yield valuable terpenes for this purpose is what I wonder.
