Population Changes of Pseudomonas glycinea on Germinating Soybean Seeds. J. A. Laurence, Research Assistant, Department of Plant Pathology, University of Minnesota, St. Paul 55108; B. W.

Significantly larger populations of two races of Pseudomonas glycinea developed on germinating seeds of a susceptible cultivar, but not on a resistant soybean cultivar, thus demonstrating pre-emergence host-pathogen specificity. Host emergence was reduced in some race-cultivar combinations in the greenhouse, but not in the field.
