Lodging resistance is an important trait in sugarcane breeding. Accurate evaluation of the lodging resistance of germplasm resources is of great significance for breeding lodging-resistant varieties. This study investigated the effects of agronomic traits and stalk fiber components on lodging resistance using 16 sugarcane germplasm materials. The key traits affecting lodging resistance were identified by grey correlation analysis, and the comprehensive evaluation was carried out by using membership function method and cluster analysis method to screen excellent lodging resistance germplasm and its key traits, so as to provide germplasm resources and theoretical reference for sugarcane lodging resistance breeding. The results showed that the sugarcane germplasm materials with the strongest lodging resistance were Yunzhe 17501, Guiliu 05136 and Yuetang 93159. Among them, stem diameter, effective stem number, plant height and cellulose content were the key factors affecting the lodging resistance of sugarcane.
