Pathogenicities of the five BBWV isolates were differentiated by the reactions on the 29 host plants including Chenopodium amaranticolor. Three specific ultrastructures were observed in cells infected with BBWV The first ultrastructure was the tube made of $1\sim2$ layers of virus particles. The second one was the comb structure consists of round and angled structures. The last one was the membrane proliferation in the cytosol.
