Abstract: The Inheritance of resistance to Green Leaf Blight (GLB)caused by Pyihiuru sp, was studied, The results were as follows; "1'hc rc:,is!ance to GLB appeared to have the character of quantitative inheritance which was controlled mainly by additive gene effects, In different generations, the resistance of F 1 was similar to the mean level of its parents, But I' Z was more susceptable than F,.The reactions of their backcross progenies to GLB tended to be similar to those of their recurrent parents,Therefore, the screening of resistant sources and the determination of resistance combining ability should be emphasized in the breeding program of Maize GLB resistance,In order to select an ideal hybrid,both parents should be highly resistant.

Key words: Corn, Green Leaf Blight, s Pythium sp, Additive gene effects, Combining ability
