The breeding method comprises a directional production method and a generation seed reproduction method. According to the directional production method, production areas are divided by taking Dizhou as a unit, seeds provided by different production areas are specific or exclusive, and the specific seed supply mode is the directional production method; according to the generation seed reproduction method, after seeds of a breeder are propagated, single plants are continuously selected in a propagation field, seeds are reserved once every three years to form a generation, and the mode is the generation seed reproduction method. Compared with a good seed reproduction method in the prior art, the method disclosed by the invention has the advantages that the variety character and continuous good adaptability of the flue-cured tobacco can be remarkably maintained. 本发明涉及一种保持烤烟种子种性的繁育方法，所述的繁育方法包括定向生产法、世代繁种法；所述定向生产法
