摘要

In August 2002, wheat plants in glasshouses at the CSIRO Plant Industry Black Mountain laboratories, Canberra, showed symptoms typical of Wheat streak mosaic virus (WSMV) (Murray et al, 1998), In early 2003, similar symptoms were observed on a summer field experiment at the Ginninderra experimental station, Canberra. The symptoms were characterized by a streaking or mottling of the leaves, leading to chlorosis and in some cases very severe stunting of the plant, In many cases the plants were sterile or produced shriveled seed. Affected plants sometimes showed a curling of the leaf; a symptom caused by the wheat curl mite (Aceria tosichella), the vector of WSMV (B Halliday, 2003, CSIRO Entomology, ACT 2601, Australia, personal communication).
