✦ Synopsis
The resistance of seven tulip cultivars to tulip breaking virus (TBV) was studied after mechanical inoculation by determining the number of infected plants and the level of virus in these plants over a period of one and a half years. Three cultivars ('Apeldoorn', 'Kees Nelis' and 'Lustige Witwe') appeared to be susceptible. Four cultivars ('Cantata', 'Juan', 'Madame Lefeber' and 'Princeps') showed a high degree of resistance. The number of infected plants of the latter cultivars was low and virus could not always be detected in the plants at the different sampling dates. Virus could not be detected in these plants after storage. These results indicate that the virus may disappear from or was not detectable in these plants. The levels of infection found are discussed with respect of its significance in studies of TBV in tulips.
