The sensory value of dry beans (Phaseolus vulgaris L.) is one of the traits that most influence consumer’s choices. It is often argued that the process of genetic improvement might reduce the sensory value of dry beans through negative genetic correlations among traits or through the remnants of the donor genome that are interspersed with the recipient genome through backcrossing. However, ther...

Pseudomonas syringae pv. phaseolicola (Burkholder) Young et al. (Psp) causes halo blight, which is a serious bacterial disease of common bean (Phaseolus vulgaris L.). Several resistance (R) genes have been discovered in host differential cultivar ZAA 12. Our objectives were to further characterize and enable marker-assisted selection (MAS) of the Pse-2 gene in ZAA 12 purported to have broad eff...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

Ochwo-Ssemakula, M., Sengooba, T., Hakiza, J. J., Adipala, E., Edema, R., Redinbaugh, M. G., Aritua, V., and Winter, S. 2012. Characterization and distribution of a Potyvirus associated with passion fruit woodiness disease in Uganda. Plant Dis. 96:659-665. This article describes the incidence and etiology of a viral disease of passion fruit in Uganda. Symptoms, including those characteristic of...

A periodic comparison of cultivars is essential to assess selection gains, determine deficiencies, define objectives, and set breeding priorities. Our objective was to assess the progress, or lack thereof, achieved in improving yield, plant type, maturity, and resistance to major bacterial, fungal, and viral diseases of dry bean of the western USA from 1918 to 1998. Twentyfive great northern, p...
