Abstract:【Objective】 Under the natural disease conditions in the solar greenhouse, 180 tomato germplasm resources are identified for disease resistance in order to screen multi-resistance materials and lay a foundation for the breeding of multi-resistance tomato in Ningxia. 【Methods】 The disease types were determined according to the disease symptoms, and the disease incidence and disease index were used to determine the disease resistance grade of 180 tomato germplasm resources to the late blight, leaf mold and early blight by 5-point sampling method. Finally, the fuzzy membership function method was used to evaluate comprehensively the disease resistance of germplasm materials. 【Results】 All the 179 tomato materials had late blight, leaf mold and early blight, and only 1 material had developed late blight and leaf mold, but not early blight. The incidence of late blight was the most serious, followed by leaf mold, the incidence of early blight was the lightest. There were 5, 25 and 50 materials with above “resistance” grade to the late blight, leaf mold and early blight, respectively, which accounted for 2.78%, 13.89% and 27.22% of the tested materials. 16 materials were screened out, all of which reached the “middle resistance” grade to each of the three diseases. Materials 63049 and 63054 ranked the top 2 in the comprehensive resistance, and the average value of membership function was 0.98 and 0.93 respectively. 【Conclusion】 These two materials,63049 and 63054, are all above the disease resistance grade and have excellent comprehensive resistance. They can be used as multi-resistant tomato germplasm resources.
Keywords:tomato  germplasm resources  leaf disease  disease resistance  evaluation
