Natural infection of the native pasture legume, Glycine latifolia, by alfalfa mosaic virus in Queensland

Abstract

The native pasture legume, Glycine latifolia, growing in experimental plots in south-east Queensland sometimes showed a yellow mosaic symptom, which was associated with a sap-transmissible virus identified as alfalfa mosaic virus. Inoculation with the virus reproduced the yellow mosaic disease in three lines of G. latifolia, but two other lines showed resistance in both inoculation tests and the field.
