Dennis Halterman

Dr. Dennis Halterman, a Research Geneticist with the USDA-ARS in Madison, WI, leads research on improving potato disease resistance using wild potato germplasm. His work focuses on identifying useful resistance traits, determining their genetic basis, and understanding the molecular mechanisms behind them. The research develops disease screening methods, genetic resources, and molecular tools to incorporate novel resistance genes into cultivated potatoes. Outcomes include DNA markers linked to resistance, improved breeding strategies, and the development of both biotech and traditionally bred potato clones with enhanced resistance. This work reduces the need for chemical applications, increases agricultural sustainability, and provides valuable resources and knowledge for other researchers in plant disease resistance.
