| Summary: | In California, first-generation table grape vineyards were planted on their own roots.
But in recent years growers have been replanting onto acreage previously in grapes
more often. Grafted plants are being sought to overcome nematodes and other site-related
problems. We investigated the etiology of the decline and death of ‘Redglobe’ table
grape scions propagated on different rootstocks, using a series of greenhouse and
field experiments, and reverse transcriptase-polymerase chain reaction (RT-PCR) assays.
We determined that a specific graft-transmissible agent was closely associated with
declining young grapevines. The ‘Redglobe’ closterovirus that we identified was given
the trivial name Grapevine rootstock stem lesion associated virus (GRSLaV). |
