Research Interests: My program focuses on improving sweet corn by breeding and the discovery of genetic information that will be useful for sweet corn improvement. I direct a sweet corn breeding program that generates commercially useful inbreds and hybrids. In the breeding program we make extensive use of tropical and other non-sweet germplasm. Our genetic research centers on three areas 1. The relationship between the development of the maize plant and pest resistance. 2. Endosperm mutants and their effects on quality, germination, and cold tolerance. 3. Phylogenetics and evolution of sweet corn. A fourth area of research involves participatory breeding and on farm research for organic crop production.
