Abstract: Abstract: 【Objective】The study screened the molecular marker linked to the tomato Fulvia fulva resistant gene.【Method】With a F2 population between a resistant and a susceptible parent (03036×03748), the linked marker was screened by BSA method and RAPD technology.【Result】Two special bands were found at 500bp or so using F2 plants. The marker was tightly linked to the tomato Fulvia fulva resistance gene, and the genetic distance was 8.7cM. Sequencing of the fragment indicated that the length was 619bp and 559bp respectively.【Conclusion】The study provided a molecular method to identify tomato Fulvia fulva resistance , and can be used in molecular marker assisted selection.
