Professional Responsibilities and Activities

Breeding of dry bean varieties to select plants that are resistant to rust, white mold, common bacteria blight, and root rots; that have desirable qualities related to water efficiency and minimum tillage systems; and that have a more upright architecture, allowing direct harvesting.
