The results showed that 9 pathogen collections of Sporisorium reilianum were divided into 3 pathogenic types in which there were type A with high pathogenicity, type B with moderate pathogenicity and C with weak pathogenicity. Type A were originated in most important corn-grown areas including Changchun ,Jilin,Gongzuling and Changling where corn head smut usually occurs severely, type B were collected from Siping,Tonghua ,Songyuan,Yanbian, and type C were collected from Baicheng where corn head smut usually occurs very lightly.

致病类型A为强致病类型，来源于吉林、长春、公主岭和长岭，是玉米丝黑穗病发生最严重的地区；致病类型C为弱致病类型，分布于白城地区；致病类型B其致病性介于A、C类之间，主要分布于四平、通化、松原和延边地区。
