Abstract

One hundred and ninety-two sugarcane clones were evaluated for resistance to rust (Puccinia melanocephala) H. Syd. and P. Syd.) and to smut (Ustilago scitaminea Syd.), between March 1985 and March 1988. Fiftynine clones (31%) were resistant to both rust and smut in plant cane, and in the first and second ratoon crops. Incidence of smut increased after ratooning. Some 81 to 96% were resistant to rust. Rust resistance remained unchanged in plant cane and ratoon crops.
