Abstract

Promising clones in the third selection phase of the sugarcane genetic breeding program in Paraná State, Brazil, were evaluated for the severity of sugarcane rust (Puccinia melanocephala) incidence under natural infection. The evaluation was carried out in a sugarcane plant and a sugarcane ratoon cycles, from 1998 to 2000. The assessment of severity identified fifteen clones with rust resistance reaction in the sugarcane plant cycle. Of the 41 evaluated clones, 18.2% presented slightly resistant to susceptible reaction. The highest rust incidence was observed in the early phases of sugarcane crop development, from three to six months. Among the clones with resistance reaction to rust, five were derived from the same female parent (RB855589). This fact demonstrates the good potential of this genotype for crosses looking at clones with rust-resistance reaction.

KEY-WORDS: Saccharum spp.; Puccinia melanocephala; resistance; selection.
