It makes sense too, the nanners show up about 2 weeks before harvest and many times, they're difficult to see, so it's understandable that unless the original growers are sophisticated, they won't select against these traits. Full blown uncontrollable hermis are less common, probably because they're easy to ID during preflowering and can therefore be easily cull before they become a problem.
Despite temperatures going down to about 4C at night and being exposed to heavy rain for many days in a row, the manipuris are still showing no signs of botrytis! In contrast, Kumaoni showed a little bit of botrytis under the same conditions and was subsequently chopped a little bit early. We'll see how the manipuris handle more cold. At this rate, the earliest flowering plant is predicted to finish mid December, if it can make it that long!
it's worth emphasising that this trait is likely being expressed as a response to unfamiliar environmental factors, conditions, and methods of cultivation
also, re. late intersex pollen:
notably, all of the strains you mention are cultivated as fully seeded (hashish plants) or partially seeded (Manipuri, Malawi) crops
certainly the fully seeded crops are unlikely to form viable seeds from pollen shed 2 weeks before harvest...
I have been in many Himalayan fields and can only recall seeing a male flower on a fully flowering female plant once (in mid-West Nepal)
I suspect that a combinaton of factors such as climate, nutrients, pests, soil, and daylight changes can all be factors that act as unfamiliar environmental stressors
I recently had an email from a guy who grew most of these strains you mention outdoors in soil with no problems...
he then grew the same strains in pots, moving the plants indoor and outdoors during winter, and then found that several hermied on him
one thing I am sure of: in their native environment these strains do not show this trait nearly as often as they do when cultivated in unfamiliar conditions
