This article reports agronomic characteristics of the landraces. The twenty maize landraces were analysed by the method of Grey systematic theory. It was showed that the plant height mainly affected spike width, the ear height mainly affected the ear length. If plant height and ear height were low, the grain weight per plant was low. The number of leaves not only had remarkable effect on the ear length,ear width and grain weight per plant, but also had effect the use of landraces. Good inbred line and hybrids could be selected from corn landraces with short growth duration .Eight varieties of Baitoushuang,High-oil corn,Luoyan No.85,Baihe,Erxia,Pingzong No.2,Goldqueen,Bendihuang had good comprehensive agronomic characters which could be used in breeding programs.
