Hangbaiju (Chrysanthemum morifolium) is popular among consumers because of its anti-inflammatory, antioxidant and liver-protecting effects, and it has both medicinal and ornamental value. With the expansion of planting scale, pests and diseases have become the main obstacles affecting yield and quality. Although chemical pesticides are still the main means of prevention and control, there are problems such as increased resistance and environmental pollution. In order to promote green planting, this study screened out a number of resistant chrysanthemum varieties, and combined field natural infection experimental analysis, artificial inoculation experiments and molecular marker analysis to clarify the role of resistance genes, like CmWD40 and CmWRKY8-1 in the defense mechanism. The results showed that, these varieties can effectively reduce the incidence of pests and diseases while maintaining yield and quality, and adapt to the green prevention and control system. This study provides strong germplasm support and theoretical basis for the sustainable cultivation of Hangbaiju, and helps its promotion and application in ecological agriculture and organic certification paths.
