The paper provides information on the virus and virus-like diseases detected in grapevine growing in the Murray Valley, specifically leafroll, grapevine yellow speckle, fleck, fanleaf virus, and enation.
Most infected grapevines have more than one disease, the common combination is leafroll and yellow speckle.
Enation occurs in Sultana clones which are free of FLV, but infected with leafroll and GYS.
Indexing results indicate that different strains of leafroll exist.
Characterisation of these strains could be of value because some strains may not be economically important.
Indexing results support the hypothesis that many cultivars imported from the old world before rootstocks were used for phylloxera were relatively free of virus diseases, the main exceptions being Sultana, Currant, and Waltham Cross.
Subsequent spread was due mainly to indiscriminate propagation from grapevines infected before importation or by grafting on infected rootstock or other cultivars.
