Susceptibility of chrysanthemums to tomato spotted wilt virus

In Canada, 36 cultivars of florist's chrysanthemum (Dendranthema grandiflora) were compared in regard to their susceptibility to tomato spotted wilt virus (potential EPPO A2 organism).
The virus was more widely distributed in tissues of susceptible cultivars than in resistant ones. The virus also was detected more easily in leaves and stems showing symptoms. All cultivars, regardless of their degree of resistance to tomato spotted wilt virus, were infected latently. The latent infections were detected most easily in roots.
