Research
research overview
- The research focuses on breeding for resistance to economically important disease and environmental stress constraints of vegetable crops. These goals include the selection of snap beans with resistance to aphid-transmitted viruses, common bean rust, white mold and heat stress, Brassica vegetables with resistance to black rot and heat stress and novel tomato traits. The research includes the adaptation of crops to the Great Lakes Region and tropical/sub-tropical environments, including Sub-Saharan Africa. The research involves multi-state, multi-disciplinary and international collaborations with supporting laboratory techniques including molecular breeding and diagnostics, cellular techniques including flow cytometry, tissue culture and embryo rescue, and a large focus on controlled environment screening.

Teaching
teaching overview
- To develop courses to maximize creative thinking and exposure to different approaches in plant breeding. To give emphasis on real world utilization of breeding and to provide comprehensive, up-to-date reading material encompassing traditional and modern breeding approaches. The teaching component will also include efforts in a team taught class offered to upper level undergraduates and graduate students during the Fall semester (PL BR 403). The class will be modified to incorporate concepts and considerations unique to breeding horticultural crops – filling a much needed hole in the classes offer graduate students in Horticulture. This class will be cross-listed to Horticulture in 2002 as with the class PL BR 618.
