Gene for resistance to plant disease

A more efficient breeding against Cercospora leaf spot disease， or the development of new resistant lines， is enabled via the provision of the Cercospora resistance-mediating gene according to the invention; in particular， a dominant resistance effect in the target plant is evoked by the property of the identified gene alone. The Cercospora resistance-mediating gene， and embodiments of the present invention that are described in the preceding， offer additional applications， e.g.， the use of the resistant gene allele in cis-genetic or trans-genetic approaches， with the goal of developing new resistant cultivars.
