Interpretive Summary:

Technical Abstract: Bush Blue Lake (BBL) snap beans are grown in the Willamette Valley of Oregon for canning and freezing. While they have desirable processing and production traits compared to other snap beans, plant architecture, seed production traits, and white mold resistance need improvement. Previous breeding work at OSU demonstrated that it is very difficult to recombine Oregon BBL materials with other snap beans. Using molecular markers Myers and Davis (2002) showed that Oregon BBL snap beans are of the Mesoamerican center of origin where as most other North American snap beans are of the Andean center of origin, which could explain the lack of useful recombinants between these types. A molecular marker linkage map should allow us to monitor the introgression of new traits while maintaining the BBL traits in future germplasm and cultivar development.
