Marcial A. 'Talo' Pastor-Corrales

Research Plant Pathologist

Dr. Pastor-Corrales conducts research on host-resistance of beans using traditional and molecular biology based approaches to resolve the production losses in common beans caused by diseases. This research will provide information needed to understand the diversity of certain bean pathogens and to characterize and use disease resistance genes. This research is expected to result in the production and release of dry and snap beans with commercial value and resistance to several diseases.
