Abstract : |
African eggplant (Solanum macrocarpon L.) is commonly distributed in Cameroon as a vegetable crop for its edible leaves. A severe mosaic disease symptomized as systemic mosaic on leaves and fruits, leaf mottling and crinkling, fruit necrosis, plant stiffing and stunt were commonly observed. Forty-one virus isolates were obtained from field samples and two viruses were detected. Isolate Au27 caused similar symptoms as the natural infection on S. macrocarpon. The principal virus (Au27) was identified as eggplant mottle crinkle virus that reported from S. melongena, an eggplant species well distributed from other countries. Isolate Au24 was identified as the complex of Au27 and tobacco mosaic virus (TMV) according to biological, molecular, morphological and serological tests. 14.6% isolates were found belonging to Au24 and 85.4% to Au27. No additional symptom was caused by TMV infection when co-inoculated with Au27 onto S. macrocarpon, |
