VIRUS DISEASE OF LILIES IN KOREA

K. Lee, H. Choi, G. Choi, J. Kim
Incidence of virus diseases on lilies in plastic houses at Kwangju and Jeju areas was 95,4% in average for Lilium longiflorum Thunb., 'Georgia' and 74.4% for the foreign cultivars. The major virus disease symptoms were white streak, mosaic and malformation on L. longiflorum Thunb., Georgia' and 'Hinomoto', L. speciosum Thunb., 'Stargazer', L. elegans Thunb., 'Enchantment' and 'Connecticut King'. Vein chlorosis was only observed on L. speciosum Thunb., 'Stargazer'.

Virus particles of filamentous, flexuous rod and rigid rod with 200–800 nm in length were found in 35 out of 50 samples by electron microscopy, but they were not isolated purely. There was no relationship between the virus symptoms and kinds of viruses.

Four different viruses, broad bean wilt virus (BBWV), cucumber mosaic virus (CMV), tomato ringspot virus (TomRSV) and lily mild mosaic virus (LMMV), were reported in Korea. BBWV and CMV were reported from lily showing complex symptoms of dwarfing, malformation and colour breaking. TomRSV was isolated from lily showing yellow stripe. LMMV was isolated recently from imported lily, L. elegans Thunb., 'Hinomoto', showing yellow streak, Morphological characteristic of LMMV was isometric particles of 27 nm diameter. Molecular weight for the coat protein of LMMV was 2.6 x 104 in 12% SDS-PAGE. The virus could infect 20 plants out of 23 tested plants by mechanical inoculation including Vigna unguiculata. The virus was not transmitted by aphids, Myzus persicae 'Sulz'. In ELISA for LMMV and TomRSV on 185 lily samples collected from Jeju, Kwangju and Seosan areas, the infection rates of lily with LMMV, TomRSV and both viruses were 26.3%, 50.2% and 23 2%. respectively.
