The progress levels of symptoms is different.The aggressively has polymorphism. The pathogenicity of different isolates in same cultivar has polymorphism, or the host reaction type of same isolate in different cultivars has polymorphism.The host reaction type has differentiation. There are seven types of host reaction in cultivar and inbred after infected by GLS pathogen:Rectangular lesion without chlorotic halo, Rectangular lesion with chlorotic halo,Irregular lesion without chlorotic halo,Irregular lesion with chlorotic halo, Spot lesion with chlorotic halo,Rectangular and irregular lesionand Rectangular and spot lesion. The host reaction type is coalesced lesion when disease severely. Frequency of each reaction types is different.
