Screening of Tomato Cultivars for Resistance to Pulsarium Wilt in Eastern States of Nigeria

摘要

The causual organism of the out-break of wilt disease of tomato in the Imo and Rivers States of Nigeria was identified as Fusarium pallindoroseum (Berk and Rav) Booth and Sutton, and its pathogenicity was established. Experiments were designed to screen five tomato cultivars for resistance to F. pallidoroseum . Four methods were employed in the screening experiments. The results of all the methods used showed the cultivar IFe-l as the most susceptible (65 %) while the Chef Cultivar was the most resistant with less than 10 % of the test plants wilting.
