Hermaphroditism in Marijuana (Cannabis sativa L.) Inflorescences – Impact on Floral Morphology, Seed Formation, Progeny Sex Ratios, and Genetic Variation
Cannabis sativa L. (hemp, marijuana) produces male and female inflorescences on different plants (dioecious) and therefore the plants are obligatory out-crossers. In commercial production, marijuana plants are all genetically female; male plants are destroyed ...www.ncbi.nlm.nih.gov
read it and you will have your answer about Hermies
Its a Lab test done here in Canada with the affirmation that Hermaphrodite Cannabis pollen will produce an outstanding of Female seeds, with a rate as high as 95%
yes. i am aware of that study. they used commercial seed, and essentially proved that hermies make hermies. they counted hermies as female and have been criticized on that.
edit : also they worked with autos, and femmed seed. you work with regs if you want it stable.
hermies do occur in the wild, but it's something on the order of 2 - 5%. commercial growers running regs see about the same. the few commercial growers who have posted on this concur. the fellow with the legacy farm had observed that.
edit more : the one thing they did do correct was collect pollen and not use selfed seed. using hermie pollen on a stable reg female will result in a much higher proportion of female outcomes. it's the selfed seed that is the issue.
we ran a 200 plant med grow for 10 yrs. we ran regs, had a breeding program, and femmed seed with sts a couple times. during that 10 yrs we had a total of 8 plants voluntarily hermie.
