Avoidant/resistant rather than tolerant olive rootstocks are more effective in controlling Verticillium wilt.

ABSTRACT: The identification of rootstocks of low susceptibility to Verticillium dahliae can become a valuable procedure to achieve effective control of Verticillium wilt in the olive grove. This not only involves the identification of suitable genotypes, but also the study of the interaction between the rootstock and the grafted scion. Thus, a rootstock that prevents or minimizes V. dahliae proliferation (avoidance/resistance strategy) can have very different effects on a susceptible scion compared to a rootstock that shows few or no symptoms despite being infected (tolerance strategy). Both resistance and tolerance mechanisms have been recently identified in wild olive genotypes with low susceptibility to V. dahliae. When used as rootstocks of the highly susceptible variety 'P
