A multiplex RT-PCR (mRT-PCR) assay was developed for the detection of the recently reported viruses, Cherry virus A (CVA), Little cherry virus 1 (LChV-1), and Little cherry virus 2 (LChV-2), in cherry plants in Korea. Eight sets of primers were designed for each virus and their specificity was tested by using various combinations of mixed primer sets. From the designed primer sets, one combination was selected and further evaluated to estimate the optimum temperature and detection limits of the mRT-PCR. A newly developed mRT-PCR assay was also tested using 20 cherry samples collected in the field. This mRT-PCR assay may be a useful tool for field surveys of diseases and the rapid detection of these three viruses in cherry plants.
