The research and experimental plot for peach and nectarine at University of Kahramanmaras Sutcu Imam (KSU) has been established in the growing period of 1998-1999. The severity and distribution of five virus diseases of peach and nectarine trees were determined during the 2004-2005 growing season. A total of 262 samples were individually collected and tested by DAS-ELISA for Prunus necrotic ringspot virus (PNRSV), Prune dwarf virus (PDV), Plum pox virus (PPV), Apple chlorotic leafspot virus (ACLSV) and Apple mosaic virus (ApMV). A total of 22.9% of ELISA-tested samples (60 out of 262) were infected by one (22.5 %) or two (0.4%) viruses. PPV was the most widespread virus (11.45%), followed by PNRSV (7.25%) and ACLSV (3.82%). ApMV and PDV were not detected in the all tested samples. These results demonstrated that we are facing to the problem of not having healthy nursery stocks for fruit trees.
