Lodging resistance in crops is a complex quantitative trait， and precise phenotyping is pivotal for mining lodging resistance genes and elucidating their underlying genetic mechanisms. However， accurate field-based evaluation of lodging resistance in rice germplasm resources has long been a major technical challenge for crop breeders. To address this issue， our research group has developed a standardized technical regulations building on prior relevant research. This protocol encompasses the entire workflow of field-based lodging resistance evaluation， specifying operational norms and basic requirements for all key stages： General experimental requirements， land preparation， planting practices， water management， fertilization， disease， pest and weed control， and lodging resistance assessment at the mature stage. It is intended to serve as a robust technical reference for the systematic evaluation of lodging resistance in rice germplasm resources. This protocol is applicable to the field-based evaluation of lodging resistance in mature rice germplasm resources across all rice-growing regions in China.
