Narrative

Type IIa growth habit, characterized by an erect plant with both a strong main stem and basal branches. This feature gives excellent lodging resistance. Yield average 2,708 kg-ha-1 over 18 test sites in Michigan from 1998-2002 and 3,942 kg-ha-1 at Othello, WA in 2002. Dry seed characteristics meet the requirements of commerce. Individual seed colored an attractive garnet with an intense red saturation and a noticeable black hilum ring. Seeds oval, 12.0 x 8.0 mm in length and width, respectively, plump at the surface tangental to the hilum and gently rounded at the apices. Seeds weigh 40.0 g 100 seeds-1. Flowers white, averages 470 mm in height at physiological maturity, blooms about 45 days after planting and matures between 87 to 100 days. Has the bc-1(2) gene for resistance to bean common mosaic virus and the Ur-3 gene for resistance to Race 53 of bean rust disease (Uromyces appendiulatus). Is the only small-red commercial cv. resistant to bean rust disease. Desirable canning quality based on the judgements of sensory panelists who rated the cv. on a seven-point hedonic scale where 7.0 is the most and 1.0 is the least desirable perceptions for a trait. Average score of 5.0 for visual appeal, which is a function of the amount of clumping of beans in the can, loss of bean integrity (splitting), canning broth characteristics of viscosity, color, and exuded starch, and cooked seed characteristics of color, size and shape for the market class. Cooked bean Shear resistance, which measures the deformation properties of a sample and estimates texture, was determined with an Allo-Kramer Shear Press. Value of Shear resistance is 63 N x 10-1, with the ideal range of Shear resistance values for small-red bean being 64-74 x 10-1 and the acceptable range of 54-83 N x 10-1. Hydration ratio 1.8 and 1.5 washed drained weight ratio, which are ideal values for thermally processed dry beans.
