Abstract: Three methods of cluster analysis based on phenotype characters,heterosis,and RAPD's molecular markers,were compared in terms of methodology of heterosis grouping with 15 inbred lines used dominantly in commercial hybrid maize production in China.The analysis of phenotype cluster influenced by environment remarkably did not fit with the pedigree of the 15 entries.The heterosis cluster fitted better with the pedigree.RAPD's cluster fitted best with the pedigree for this method is based on plenty of molecular markers without functional phenotypic and multiple effects and epistasis,which are not influenced by growing and development stages and environment.RAPD's cluster is a reliable approach to distinguish the heterosis groups for inbred lines.

Key words: Inbred line of maize, Phenotype chatacter, Heterosis, RAPD, Cluster
