520 _aBased on dialle I and design II analyses, besides application of molecular markers (RFLP, SSR and RAPD), most of the predominant inbred lines used in Chinese maize breeding program can be clustered into three heterotic groups or six sub-groups. The first group is of domestic germplasm named as Dom, and consists of Sipingtou and Luda Red Cob sub-groups. The second group is of Reid germplasm and consists of BSSS and PA sub-groups. The third group is of Lancaster (Lan) or non-Reid germplasm. The predominant heterotic patterns can be summarized as Dom x Lan or Dom x Reid. Luda Red Cob x Lan is the predominant pattern in spring maize area in north China. Sipingtou x Lan is early maturing, and is mainly used in the northeast provinces and north part of summer maize area. Sipingtou x PA is usually used in the summer maize area. Heterotic pattern used in the southern provinces has not been established. Maize breeders in China tend to produce combinations between local germplasm and exotics. All the patterns currently can be summarized as Local x Exotics, and the patterns are usually of dent x flint type.
