The invention discloses a different-place seedling south numerous added-generation breeding method for tobaccos, which comprises the following steps of: after the local bred seeds of the tobaccos are mature, locally sowing the seeds in a seed maturing area, preferably in late July or late September; raising seedlings at a different place for 55 to 65 days in a mode of float seedling; then transplanting the tobacco seedlings to a Hainan breeding area in a mode of air transportation and the like; and after the tobaccos are harvested, taking back the tobacco seeds to a local test area to perform sowing. The method can avoid the influence of severe weathers such as typhoon and the like on breeding at the early stage of the traditional tobacco south numerous added-generation seedlings, meanwhile optimize the local tobacco production and staffing conditions of breeders, and shorten long-term on-business time of the breeders.
