The survey concerning detection of viral disease LChD (Little Cherry Disease) started in VSUO Holovousy in 2007. The Little Cherry Disease is caused by viruses from the genus Closterovirus (Closteroviridae family). The positive control (LChD-infected plants) was obtained from Germany and transformed into the viral germplasm collection in VSUO Holovousy. Symptomatic trees were selected and tested by RT-PCR method. Different parts of plants were sampled from suspected trees to observe the dynamics of virus detection during the growing season. According to obtained results, young leaves from sprouted buds, blossoms and leaves sampled in autumn represented the optimal plant material for LChD detection. Prunus avium cultivar Canindex is considered to be the best woody indicator for LChD detection.
