Calla lily (Zantedeschia spp.), belonging to Araceae, is a popular ornamental crop in Taiwan and many other countries. Several diseases caused by viral pathogens are important in calla lilies. The calla lily research program at TARI sought to develop reagents enabling the detection of viral pathogens in calla lily tissues and to apply these reagents in its propagation program in order to produce virus-free calla lily seedlings. The research efforts resulted in the development of nine reagents for practical application in commercial calla lily production.
Symptoms of five potyvirus diseases of calla lily.
