The vegetable improvement program at Geneva focuses on the breeding and genetics of vegetable crops. The goals include the introgression of host plant resistance to economically important pests, tolerance to environmental stresses and the selection of niche-market crops and traits. The program supports the needs of commercial growers and processors, consumers, the seed industry, sustainable agriculture, international agriculture, integrated pest management, maintenance of biodiversity and new markets.

Research Focus

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.
