Technical Abstract: 'Newport' navy bean (Phaseolus vulgaris L.) was developed and released by the Michigan Agricultural Experiment Station and the USDA-ARS in 1995 as a determinant, mid-season cultivar with multiple disease resistance and favorable processing quality. 'Newport' was developed to incorporate erect plant stature and additional resistance to anthracnose disease into the Type I navy bean growth habit. 'Newport' is resistant to all known North American isolates of the organism that causes anthracnose disease. 'Newport' carries the single dominant hypersensitive I gene resistance to Bean Common Mosaic Virus (BCMV) but is susceptible to the temperature insensitive strains of BCMV which induce top necrosis and the black root reaction. 'Newport' is homozygous for the Ur-3 rust resistance gene which conditions resistance to all indigenous rust races prevalent in Michigan. 'Newport' yielded an average 2,450 kg. ha**1 over 33 locations from 1990- 1994. 'Newport' has large ovoid seed which averages 22 g per 100 seed and ranges from 19-23 g. The seed is similar in size and color to the industry standard, 'Seafarer' but brighter in color than the commercial 'Mayflower'. In canning trials 'Newport' performed favorably in subjective and instrument based evaluations. A trained panel of judges rated 'Newport' 3.0 for overall canning quality on a 5-point hedonic scale where 1 and 5 represent the minimum and maximum expression of the trait, respectively. 'Newport' was no different for cooked color, and the hydration and washed drained weight ratios than other commercial navy bean cultivars. Texture was estimated with a Allo-Kramer Shear Press and 'Newport' averaged 45 kg. 100g**-1 which is within the 40-70 kg. 100g**-1 range denoting a satisfactory texture score for processed navy beans.
