Abstract: Heterosis and inheritance of commodity characters were studied by heterosis analysis and Hayman. The results indicated that bald length and kernels per row in super sweet corn were easily affected by parents which the additive effect made main rule. Inheritance of sugar content and pericarp thickness conformed to the “additive-dominant” model and the characters were controlled by more than 3 pairs of genes, which the heritability in a narrow sense were respectively 53.0% and 29.6%.Sugar content was controlled by additive effect having more importance than dominant effect and pericarp thickness was controlled by dominant effect having more importance than additive effect . there existed super dominant effect.

Key words: Super sweet corn, Heterosis, inheritance, sugar content, pericarp thickness
