1985 Fall Armyworm Symposium: Plant Resistance: Resistance in Corn (Zea Mays) to the Fall Armyworm Spodoptera Frugiperda: The Impact of Public Research on Commercial Seed Companies

J. L. Overman


The fall armyworm, Spodoptera frugiperda (J. E. Smith), is an economic pest of late-planted corn, Zea mays L., in the southern United States and it reduces the market potential for the currently available commercial hybrids. Commercial hybrid seed companies are responsible for developing and marketing the majority of the commercial corn hybrids. These companies are still dependent on public institutions to identify and release resistant germplasm, develop insect rearing methods and to design efficient breeding techniques for developing resistant elite lines. This paper discusses the major discoveries from the public sector and their impact on commercial seed research.
