STUDIES previously reported (7) utilized reciprocal translocations in genetic analyses of the resistance to the leaf blight caused by Helmintrosporium turcicum Pass., carried by inbred lines Mo2lA and NC34. Both of these lines have been highly resistant to this disease in numerous experiments (3, 4, 5, 6), and both lines also have been used as sources of resistance for transfer to susceptible inbred lines (6). As a result of this breeding work, recovered strains of several leaf-blight susceptible inbred lines have been developed which carry appreciable resistance to infection by H. turcicum. The present studies were undertaken to determine, if possible, the specific genes responsible for differences in the leaf-blight reaction of 3 disease-
