This disease is caused by the quantity of Sporisorium reilianum in soil and infected soil ,and the infected degree lies on varietis＇ resistance and environmental effect of the seedling period. The resistance to this disease belongs to Quantity Heredity. According to this point, widening germplasm is the primary method in selecting resistant varieties.
