Southern corn rust (Puccinia polysora Underw.) has caused losses in late-planted maize (Zea mays L.) in the southern United States in 1972, 1973, and 1974. Two susceptible × resistant crosses to this rust were made, and the parents, F1 F2, and BC1 populations were studied in the greenhouse for their response to this rust. A single dominant gene for resistance to corn rust was found in a recovered inbred line (B1138TRpp). The original source of resistance (B1138T) comes from South Africa and has resistance to Bipolaris turcicum (Pass.)Shoemaker.
