Abstract:	Leaf age at the time of inoculation was a critical factor determining the differential reaction of soybean cultivars to the leaf blight pathogen, Pseudomonas glycinea. Of 23 P. glycinea strains from Wisconsin, 22 were of race 4 and one of race 5. Of 14 P. glycinea strains obtained from the National Collection of Plant Pathogenic Bacteria, Harpenden, England, one strain was of race 1, nine strains were of race 4, and three strains were of a new physiologic race herein designated as race 9. Pathogenicity to soybean of one strain, NCPPB 1764, could not be confirmed.The reaction of several soybean cultivars to representatives of several physiologic races of P. glycinea differed from that originally reported in that a susceptible rather than a resistant response was obtained. This difference may have resulted from experimental conditions that differed slightly from those used by the original investigators
