Abstract
A simple test for determining the resistance of tomato lines toFusarium andVerticillium wilt diseases was developed. Roots of tomato seedlings at their first true leaf stage were dipped in a heavy suspension of the pathogen for 24 h. The seedlings were then transferred to small beakers containing various concentrations of Hoagland solution. The first and most severe disease symptoms appeared on susceptible cultivars grown in 25% Hoagland nutrient solution. Final results of resistance tests were obtained 10, 8 and 16 days after inoculation withFusarium race 1, race 2, andVerticillium, respectively. The test appears to be simple, results are obtained rapidly, and greenhouse space can be saved.
