Resistance to foliar blight of pepper (Capsicum annuum) caused by P. capsici was found in several plant introduction (PI) lines by using a spore suspension as inoculum in a greenhouse test. PI 201232 and 201234 had the highest level of resistance. These lines had previously been reported resistant to the crown and root rot phase of the disease. For a study of inheritance of resistance, 2 resistant cultivars, ''Fyuco'' and ''P51'', were crossed with the susceptible ''California Wonder'' and with each other. In the F1, F2, and backcross populations, resistance appeared under the control of a single dominant gene with modifiers and was the same from both sources; however, the F3 progeny did not fit a single gene hypothesis. Lines selected for resistance to foliar blight in the greenhouse were usually resistant to crown and root rot in the field. Prolonged incubation periods or very high inoculum concentrations of P. capsici could occasionally overcome resistance and result in symptoms on some resistant plants.
