A set of maize inbreds or cuhivars were screened as Sporisorium reilianum pathogen differential hosts with genetic background which current eultivars shared in China, such as inbreds B73, Ye478, Mo17, Qi319, Huangzaosi, Dan340 were identified as major ones.Sporisorium reilianum had been identified into 6 physiological dif ferential pathotype by 6 differential hosts.The result was mentioned above provided a sound basis for breeding and identifying resistant euhivars, scientifically planting resistant cultivars in growing areas as well as monitoring of pathogen differentiation.
