Root Rot Resistant Snap Bean Cultivars

Root rot caused by soil borne fungi limits the production of garden (snap) beans. Currently, a crop rotation of three to five years is the most effective management strategy used to control this disease. There is a need in the marketplace for commercial cultivars with good root rot resistance. This technology provides root rot resistant snap bean cultivars. The inventors crossed and backcrossed a root rot resistant Mexican landrace with commercial cultivars to develop lines that combine root rot resistance with improved pod and plant quality traits.

BENEFITS:

Combines root rot resistance with plant and pod quality

Allows for shorter, more flexible crop rotations

Commercial applications include canning, freezing, and fresh market

Calcium-Rich Snap Bean Genotype

Increased calcium intake is recommended for pregnant women, senior citizens, and adolescents. UW-Madison researchers have now developed a snap bean cultivar with high calcium content in the pods. Snap bean pods from this line contain approximately 20 percent more calcium than other common snap bean cultivars.

BENEFITS:

Provides a snap bean with increased calcium content

Calcium should be more bioavailable than that found in supplements

Provides relatively inexpensive source of calcium

Plant displays similar agronomic traits to other fresh market snap bean cultivars

Snap beans are popular with adolescents

May help lower the rate of osteoporosis

Attractive to organic farmers and home gardeners due to superior nutritional content
