Lilium is a perennial bulbous flower of Lily family Liliaceae, with high ornamental and economic value. However, Lily is vulnerable to virus infection, which seriously affects the yield and quality of Lily, and poses a great threat to the production, sales, especially export of Lily, and has caused huge economic losses to the related industries. Therefore, the research on lily virus removal methods and virus detection technology has important practical significance to improve the ornamental value and economic value of lily. In this study, the filaments of four susceptible lily varieties,' Valdisole' (A),'Adoration'(LA),' Ice Cube'(OT) and ‘Zantriana’ (O), were used as explants. The filaments of lily were divided into three parts, namely, top, middle, and base. In this paper, the virus detection of tissue culture seedlings induced by lily filaments was carried out by using DAS-ELISA and RT-PCR, and the removal effects of Cucumber mosaic virus,(CMV) and lily symptomless virus (LSV), two common viruses in lily, were explored, and the two detection technologies were compared. The results showed that the success rate of tissue culture seedlings induced by filament base was the highest, and CMV virus could be basically removed. RT-PCR detection is more sensitive than DAS-ELISA detection, but RT-PCR detection requires higher test conditions and technology. Therefore, appropriate virus detection methods can be selected according to actual conditions and severity.
