Nine pairs of susceptible and resistant lines of soybeans ( Glycine max (L) Merr.) representing early, medium, and late maturity were compared for yield under heavy artificial infection with bacterial pustule caused by Xanthomonas phaseoli var. sojensis (Hedges) Starr and Burk. Comparisons were made for 1966 through 1968 at Worthington, Ind. All plots were inoculated three times and severe infection resulted on all susceptible lines. The susceptible lines yielded slightly but nonsignificantly higher than the resistant counterparts. Since infection was heavier than normally occurs in the midwest, the importance of bacterial pustule on yield in this area is questionable.
