Infection degrees of tested cultivars were remarkably influenced by the soil temperature, and increased with rising temperature. Temperature over than 25°C was necessary for effective screening of resistant cultivars.
In general, infection degree of middle resistant cultivars to race 2 increased quickly under the optimum soil temperature and high inoculum concentration, and the resistant level was evaluated to be near susceptible.
