Program Overview
The primary emphasis of the vegetable breeding program at Geneva focus on the breeding and genetics of crucifer and common bean crops, in particular, cabbage, snap beans and dry beans. The goals focus on the introgression of host plant resistance to economically important pests and on tolerance to environmental stresses. These foci include breeding for resistance to black rot in cabbages, white mold tolerance in common beans, cucumber mosaic virus resistance in snap beans and heat tolerance in broccoli and common beans. There is also significant effort focused on the enhancement of crucifer and common bean germplasm in order to transfer unique traits, yield improvement and quality into commercial cultivars. This research is supported with several laboratory protocols enabling molecular breeding and selection for traits of interest. The laboratory techniques utilized in support of the breeding research include: the development of molecular markers (RAPDs, SCARs, SSRs, RT-PCR and PCR-RFLP), embryo rescue/tissue culture, and the molecular characterization of germplasm and commercial cultivars. The program supports the needs of commercial growers, the seed industry, sustainable agriculture, integrated pest management, maintenance of biodiversity and molecular research focused on crop improvement.
