Evaluation of Olive Varieties Resistance for Sustainable Management of Verticillium Wilt

Verticillium wilt resulting from infection by dahliae is one of the most devastating soilborne fungi olive tree (Olea europaea L.) worldwide. The pathogen infects a wide variety plants and can survive in soil for many years, chemicals cannot control it. Therefore, sustainable disease management strategies are suggested, with exploitation host resistance as predominant measure practice. In addition, risk assessment commonly used plant genotypes prominent issue. this respect, nine commercially grown Greek varieties (‘Amfissis’, ‘Atsiholou’, ‘Chalkidikis’, ‘Koroneiki’, ‘Kothreiki’, ‘Koutsourelia’, ‘Mastoidis’, ‘Megaritiki’, ‘Tragolia’) international interest (‘Picual’) were comparatively evaluated their to V. dahliae. roots young immersed concentrated conidial suspension order perform an artificial inoculation. We reactions 140-day period based on external symptoms (disease severity, incidence, mortality) calculated relative areas under progress curves (relative AUDPC). process qPCR was evaluate DNA vascular tissues growth parameters (height fresh weight). A cumulative stress response consider overall effect cultivars. varied significantly, ‘Tragolia’, ‘Atsiholou’ being resistant. Interestingly, tested showed significantly low level, suggesting increased industry due
