Abstract: Two sets of specific primers were designed according to LSV and LM oV CP gene sequence,and the conditions for PCR were optimized. The multiplex PCR method which can simultaneously detect the two lily viruses was developed. It was showed that all samples which infected LSV and LMoV could be amplified by multiplex PCR, yielding two specific bands of LSV (876 bp) and LMoV (662 bp). The two viruses were detected from dilutions of 104 by multiplex RT-PCR and RT-PCR, respectively. Sequence analysis on the amplified products show that the nucleotide sequences homology of LSV was 87.8% -99.3% compared with
sequences of other isolates, and LMoV was 90.1%-99.5%.
