THE MOST FREQUENT VIRUSES AMONG VARIOUS PLUM CULTIVARS IN YUGOSLAVIA |
| Author: | M. Rankovic |
| Abstract:
A large number of trees from several plum regions were tested for the presence of plum viruses, with the exception of sharka virus which has been previously established by other authors. The results obtained showed that, after sharka, the most common viruses are necrotic ringspot (NRSV) and chlorotic leaf spot (CLSV). Usually, these two viruses have been found together in mixed infections. Slightly less widespread is line pattern virus, which by its examined properties is very similar to danish line pattern virus (DLPV). The mentioned viruses were found only in plum cultivars of foreign origin. All tested local varieties were found to be free of these viruses, but sporadically some of them were infected by prune dwarf virus (PDV). | |
