[Abstract]
Based on retrospective review on germplasm sources of maize breeding in China, i.e. local landraces, overseas inbred lines, overseas hybrids and populations, it was suggested that a major of temperate inbred in China could be divided into six groups, that was, Tangsipingtou, Lancaster, Lancaster-like, PA, PB and PC. The foundation parents used in maize breeding included Dan 340, Huangzaosi, Zi330, Mo17 and Ye478 etc. In this paper, directions and priorities of research on germplasm resources and foundation parents were also proposed.
