Resistance in Maize to Corn Rust, Controlled by a Single Dominant Gene1
- M. C. Futrell,
- A. L. Hooker and
- Scott E. Gene2
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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
