Incidence, disease index, percentage of infected kernels and DON content in the kernels were measured for each variety or line following artificial inoculation of Fusarium spp. pathogens. Reactions of wheat to Fusarium infection varied among genotypes and different types of resistance. The incidence of infection for each variety or line highly correlated to the severity of colonization after infection. DON content was more correlated to the percentage of kernels infected than to the overall incidence or severity. The selected control varieties were all susceptible to FHB, while seven breeding lines demonstrated good resistant performance. New FHB resistant winter wheat varieties appealing to the actual needs are expected from them. 关键词：赤霉病抗性小麦种质资源筛选对照品种镰刀菌属严重程度冬小麦品种抗性种质
