Identification of Causal Agents of Rust of <i>Saccharum</i> spp. and Assessment of Resistance to Brown Rust in <i>Erianthus arundinaceus</i> Clones and Their Offspring.

ABSTRACT: Sugarcane rust diseases are caused by Puccinia melanocephala (brown rust) and Puccinia kuehnii (orange rust), and significantly threaten the sustainable and stable development of the global sugarcane industry. Erianthus arundinaceus within the Saccharum complex is a potential germplasm resource for sugarcane breeding and is characterized by its tolerance of infertile land, drought, and diseases. However, the research on resistance to rust in E. arundinaceus clones and their offspring (F1 and backcross with modern sugarcane varieties) is limited. In this study, a total of 201 leaf samples from Saccharum spp. hybrids with rust symptoms were collected and screened for disease occurrence. PCR detection revealed that 17.9% and 34.8% of the samples were
