Objective:
Evaluate the affects of grapevine leafroll-associated viruses and Rupestris stem pitting associated virus on yield parameters and quality attributes of grapevines.

Approach:
Two rootstock-scion-virus interactions trial blocks will be established. The proposed trial will evaluate interaction of viruses with grapevines on different phylloxera-resistant rootstocks. Virus status of each plant will be confirmed by a combination of ELISA and RT-PCR tests for the GLRaVs and the RSPaV. Documents SCA with Washington State University.
