Identification of Rose Viruses Associated with Rose Mosaic Disease in Jordan

A survey to identify rose viruses associated with mosaic disease in Jordan was conducted during December 2004 to the end of December 2005. A total of 676 rose samples were collected from different locations in Jordan (Amman, Bakaa, Jordan Valley Jarash and Mafraq). Serological tests (DAS-ELISA) indicated that rose mosaic disease in Jordan is associated with Prunus Necrotic Ring Spot Virus ( PNRSV, Genus Ilarvirus, Family Bromoviridae and Apple mosaic virus (ApMV, Genus Ilarvirus, Family Bromoviridae either as a single or mixed infection. PNRSV was the most common virus with an overall incidence of 77.4% on landscape roses, nurseries and roses planted under plastic houses for commercial use in the surveyed regions , followed by ApMV (19.8%). In addition, the results showed that the best time to detect rose mosaic viruses is spring season where the symptoms are very obvious. The survey revealed the random distribution of rose propagating materials in the country without any limitation. This is the first report of rose viruses in Jordan
