Abstract: Thirty one maize inbred lines were classified into five major groups by RAPDs:Ludahonggu group(Ⅳ-1),Lan.Ⅱ group(Ⅳ-2A),Reid group(Ⅳ-2B),Lan.Ⅰ group(Ⅳ-3) and Improved Huangzao 4 group (Ⅳ-5 and Ⅳ-6),and four minor groups:P 138 (Ⅰ),Zheng 22(Ⅱ),Zong 31(Ⅲ),Zheng 32 and U 8112(Ⅳ-4).Comparison of the result based on RAPDs with that based on pedigree,combining ability and heterosis showed that the former is basically identical with the latter,while there is little difference for some inbred lines between the two results.And some aspects about the synthetical utilization of classification results in corn breeding were also discussed.

Key words: Maize germplasm, RAPDs, Classification
