One strain of each of the 2 races of Pseudomonas phaseolicola was tested for in vitro resistance to streptomycin. The race 1 strain showed a greater resistance to the antibiotic than the race 2 strain. Resistant mutants were isolated from each strain and used to infect plants of Phaseolus vulgaris cv. Higuerillo V 345. Variation was noted in both the range of symptoms produced and in the numbers of bacteria re‐isolated from the plants. Some mutants retained their resistance after passage through the plant while others reverted back to parental type.
