Abstract: Trees were rated for their resistance to the foliar pathogens Melampsora medusae and Marssonina brunnea and the foliar and canker pathogen Septoria musiva. Many clones were found to be too susceptible to one or more diseases to be safely planted in the north central United States. The P. X euramericana clones were the most resistant to Septoria.
