Spo...The colony features of different isolates in gray leaf spot (GLS) pathogen are different on maize leaf-extract solid and liquid media. But colonies of many isolates are black, having white hyphas. Spore balls of liquid cultural are black with fluff. Growth rate of different isolates on the same medium or same isolate on two different mediums has marked difference. The fact shows that differentiation or polymorphism of GLS pathogen has marked effect in hypha growth rate. The white isolate (20-46) of GLS pathogen was obtained in natural condition for the first time. The colony feature and growth rate of white isolate is markedly different from that of other isolates. The discovery of white isolate proved that GLS pathogen has latent energy of genetic variation.Read More
