They most likely arise naturally by spontaneous mutation, and might in
some cases confer environmental benefit, though I suspect in most merely
don't disadvantage the plants.
As for trying to breed antho-free plants, I can only suggest sowing lots
of seeds and seeing what you get, or try stressing some plant tissue in
vitro - I see all manner of strange mutations on occasion (sadly seldom
viable,) including a particularly attractive albino (no chlorophyll but
antho-producing,) Darlingtonia last year. It faded away before I could
figure out how to graft it onto some normal tissue :(
Happy experimenting,
Peter
