Publication number: 20250031639Abstract: A method for screening tobacco resistance against root-knot nematode based on intensive seedling production is provided. The method has two biological properties: inducing and stimulating the hatching of nematode eggs by host root exudates, and easily infecting the root cap elongation zone by hatched second-instar larvae. The second-instar larvae hatched by the root-knot nematode eggs are continuously inoculated. After that, under cultivating the infected tobacco seedlings in shallow water infiltrating and humidifying substrate, the created temperature, humidity and air permeability conditions are suitable for disease induction. After disease investigation, disease index is calculated, and the resistance of tested cultivars is evaluated according to the disease index. The method features simple operation, high selection efficiency, and high accuracy and reproducibility.Type: ApplicationFiled: December 28, 2023Publication date: January 30, 2025Applicant: Yunnan Academy Of Tobacco Agricultural SciencesInventors: Dunhuang FANG, Bingguang XIAO, Zhiyu FENG, Zhijun TONG, Dahai YANG, Yahui WANG, Xingfu WU, Jianmin ZENG, Xuejun CHEN
