The degree of susceptibility of 40 varieties of the soybean (Glycine max L.) to a bacterial-induced chlorosis is reported. Ten varieties showed no chlorosis when given selected inoculants in greenhouse tests; 7 others proved to be negligibly susceptible; 11 varieties showed a light or variable susceptibility; 6 were moderately susceptible; and 6 were highly susceptible. The results are discussed in relation to nodulation and symbiotic nitrogen fixation and yield.
