    Abstract

    Three blocks of Chardonnay in one vineyard in the Buckland Valley of Victoria, Australia, were surveyed over 4 years for grapevine yellows disease (GYd). Buckland Valley grapevine yellows phytoplasma (BVGYp) was the only phytoplasma detected by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis in GYd affected grapevines. GYd affected many grapevines and was characterized by remission of disease, some recurrence and occurrences in previously unaffected grapevines. A regional survey of the Buckland Valley indicated that both GYd and BVGYp occurred in the same restricted grape growing area. Within this area, BVGYp was detected in two vineyards that had been established using planting material from different sources. One could therefore speculate that BVGYp was present in these grapevines as a result of aerial transmission and was not present in the original planting material.
