However, the research on resistance to rust in <i>E. arundinaceus</i> clones and their offspring (F1 and backcross with modern sugarcane varieties) is limited. In this study, a total of 201 leaf samples from <i>Saccharum</i> spp. hybrids with rust symptoms were collected and screened for disease occurrence.
