Evaluación de líneas de tomate y su respuesta a la infección con geminivirus
Ten Lycopersicon esculentum accesions were screened for resistance to Tomato Yellow Mosaic Virus (ToYMV). Plants were inoculated with viruliferous whitefly (Bemisia tabaci), the natural vector of this geminivirus. The screened accesions were examinated for the detection signal of viral DNA and symptom development at 1-wk intervals. Only two accesions, 7113 and 9035, presented the highest level of resistance: none plants showed symptoms and dot-blot signal of viral DNA. The area under disease progress curve (AUDPC) determined the amount disease in the time. The other accesions development symptoms and DNA viral was detected.
