PRODUCTION OF HYACINTH MOSAIC VIRUS-FREE HYACINTHS AND LILY SYMPTOMLESS VIRUS-FREE LILIES BY MERISTEM TIP CULTURE
In The Netherlands, lilies are infected with tulip breaking virus (TBV) lily symptomless virus (LSV), cucumber mosaic virus (CMV), arabis mosaic virus (AMV) (Asjes et al., 1972), or tobacco rattle virus (Derks, personal communication). LSV was isolated from every plant of several Mid-century hybrids and Lilium speciosum cultivars tested.
This paper reports experimental data on the methods of producing hyacinths free from HMV. The work was initiated by van Slogteren in 1955. Data are also presented on the propagation of LSV-free lily cultivars from work done mainly by Margreet H. Bunt since 1968.
