- Abstract:
- The tomato variety ‘Huang 1501’ was used as material,the pathogenicity of 4 strains of Alternaria solani,appropriate inoculum concentration of conidia and inoculation identification of tomato germplasm were studied at seedling stage by spraying inoculation in order to provide basis for disease resistance breeding of tomato early blight.The results showed that GY7 and GY9 were the pathogens of tomato early blight,and the suitable inoculation concentration was 1×106 spores·mL-1.Conidia vary in shape,from the rod to the long oval.Every conidia possessed 0-3 vertical diaphragm (s) and 0-7 diaphragms.The size of conidia were ranged by (60-150)μm×(15-30)μm and the beak width of conidia were about 5 μm.Inoculation identification showed that there were 9 resistant germplasm,3 moderately resistant germplasms and 3 moderately susceptible germplasms.
