you would probably just breed out the ruderalis traits you might be better off breeding a iranian auto seeing how its 100% indica and veg's until its taken off of 24/0 you could breed it then grow out the seeds and take clones from the mothers that are left on 24/0 untill you find the one that act's like the iranian then hermi it and let it pollinate itself would probably be way easier then trying to isolate a ruderalis trait that has been bred into other strains
