1 Herbaceous host index is done by sap inoculation onto: Chenopodium amaranticolor, C. quinoa, Cucumis
sativus and Nicotiana clevelandii.
2 Leaf graft index is done by wedge graft onto Fragaria vesca x F. virginiana clone UC 4; F. vesca x F.
chiloensis x F. virginiana clone UC5; and F. virginiana clone UC 10 or UC 11. (Converse, 1987).
3 PCR = polymerase chain reaction.
