In spite of the successful application of chemical compounds (Maneb, Zineb) the aim to control the disease is the breeding of resistant varieties. We propose to select (phenotypically) resistant isolated plants, a method which has proved to be rather successful in the breeding of tobacco resistant to Y-virus. Until now we have selected the air-curing types SC 13 and SC 14 and the flue-curing types SCV 23 and SCV 26 from spontaneous as well as X-ray mutations, and we tested them on a larger scale for their resistance to PTA. As far as material was available a survey is given of the resistant types and different grading schemes are described
