An inbred radish line having resistance to white rust (Albugo candida), designated NIZ-AC2, is disclosed. The invention relates to the seeds of inbred radish line NIZ-AC2, to the plants and plant parts of inbred radish line NIZ-AC2 and to methods for producing a radish plant, either inbred or hybrid, by crossing the inbred line NIZ-AC2 with itself or another radish line. The invention further relates to methods for producing a radish plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other inbred radish lines derived from the inbred NIZ-AC2.
