Technical Abstract: 'Chinook 2000' light red kidney bean (Phaseolus vulgaris L.) was derived from a single plant selection made within 'Chinook' light red kidney bean cultivar. 'Chinook 2000' was developed cooperatively by the Michigan Agricultural Experiment Station and USDA/ARS. 'Chinook 2000' was released in 1998 and is a full-season, disease resistant light red kidney bean cultivar with excellent canning quality and adapted to Michigan and the Great Lakes Region of the U.S. 'Chinook 2000' was yield tested (18 locations) from 1994 to 1997; averaged 2,540 kg ha**-1 and outyielded 'Chinook' by 5% over 16 locations. 'Chinook 2000' averages 54 cm in height and exhibits an upright Type I determinant growth habit, resists lodging, has white flowers, and blooms 40 days after planting. 'Chinook 2000' matures 99 days after planting and is 3 days earlier maturing than 'Chinook'. 'Chinook 2000' has a large light red kidney bean seed averaging 58 g 100 seed**-1. 'Chinook 2000's seed is similar in size, shape, and color to 'Chinook'. 'Chinook 2000' has excellent canning quality and scored 3.4 on a 1 to 5-point hedonic scale where 1 and 5 represent the minimum and maximum of trait expression, respectively. 'Chinook 2000' has the dominant hypersensitive I gene resistance to bean common mosaic virus (BCMV) and possesses the Co-1 and Co-2 genes which provides resistance to all known North American races of Colletotrichum lindemuthianum (Sacc. & Magn.) Briosi & Cav., the pathogen causing anthracnose disease. Chinook 2000' is immune to indigenous races of rust [Uromyces appendiculatus (Pers: Pers.) Unger] prevalent in Michigan but is susceptible to Michigan isolates causing Fusarium root rot, halo blight, and common bacterial blight diseases.
