An F 1 diallel cross of eight inbred maize ( Zea mays L.) lines (four resistant and four susceptible) and parents were inoculated with Fusarium moniliforme Sheldon to determine maternal influence and gene action conditioning resistance. Reaction to this fungus was influenced by the maternal parent in hybrid combinations. Additive gene action and maternal effects were more important than dominant gene action in the inheritance of resistance to seedling blight caused by F. moniliforme . Female influence could be caused by either maternal tissue in the seed or cytoplasmic factors in the embyro.
