Also, there’s another school of thought about male selection. At least I’ve had the thought-I don’t know if it’s an actual school. I select for health and vigor. I guess if I was seeking loudness or odors and need more reasons to cull, I’ll do stem rubs.[/quote]
Sorry, don’t want to derail this, but I’ve always been taught that while you do want healthy, vigorous males, you don’t want them to be…say…a sasquatch. The idea is that if the male is more dominant than the female your offspring will be more dominant towards the father. Since we really do most of our testing with the mother, and what we really want is females with traits similar to her, mostly, you want the female to be the bigger, stronger, more vigorous plant in the equation.
This is how Shanti teaches cannabis breeding, btw, since we’re already on that topic, and it was taught to me by Subcool.
It’s dioecious due to evolution, as it forces them to be an obligate outcrossing plant, another hint here is that the flowers of cannabis are wind pollinated, so they have made no evolutionary effort to attract insects as pollinators as a way to increase their genetic diversity as is common with mono plants.
Mono plants probably also have an evolutionary role in increasing the number of females for the next generation.
I’ve heard that but never experienced it, of the hundreds of Thai I’ve grown, there is no more hermi tendencies than any other varieties. Probably 2-3 per hundred. If some people have had the experience of lots of mono Thai varieties, then I would suspect its selection not the genetics.
This is my approach too, select the males that most resemble the female. Seems logical.
