Interpretive Summary: Grape and wine production have become important sectors in Oregon agriculture during the last 25 years. Initially, the winegrape varieties planted were not grafted on rootstocks. Phylloxera, a small soilborne insect that distroys grape roots, was found in Oregon vineyards in 1990. Phylloxera resistant rootstocks provide the only economical means to control this pest. In Oregon, nearly all new vineyards are planted with winegrape varieties that are grafted on phylloxera resistant rootstocks. Rootstocks can confer other traits that are useful to growers, such as drought tolerance, nematode resistance, control of vigor and ripening time, and adaptation to soil conditions and nutrients. This paper discusses the attributes of eighteen rootstocks and their suitabilities for the wide variety of conditions found in the winegrape regions of Oregon. Growers can use this information to help them in selecting rootstocks that are best suited for their vineyard site and management inputs.
