Technical Abstract: 'Othello' pinto bean (Phaseolus vulgaris L.) (PI 578268) was developed by the USDA-ARS in cooperation with Washington State University and jointly released in September 1986 by the USDA-ARS, Washington State University, the University of Idaho, and Oregon State University. Othello is an F7 selection from the parentage 'NW-410' Pinto/2/'Victor' Pink/'Aurora' (NW- 410='Pinto UI-114'/'Sutter Pink'; Victor='Red Mexican UI-35'/1/PI 203958/2 UI-35/3/Sutter Pink/4/Aurora). Othello, under the designation GH-215, was tested extensively in the Pacific Northwest and, from 1984 to 1986, in the interregional Cooperative Dry Bean Nursery at many locations in the USA and Canada. Othello has equalled or exceeded the best other pinto cultivars in seed yield, size, and quality. Its cooking and food quality character- istics are similar to those of other popular pinto cultivars. Othello has a unique combination of very early maturity (70 to 90 days) and effective field resistance to fusarium root rot. It is also resistant to curly top virus and has i bc22 gene resistance to bean common mosaic virus (BCMV). In greenhouse tests, Othello developed mild mosaic when inoculated with NL- 4 (Mexican) strain of BCMV and only local necrotic lesions with other recently identified exotic strains NL-5 and TN-1. Othello plants are typically vigorous, short, and fairly upright. Production of breeder seed and distribution of foundation seed are under the direction of the Washington State University Seedhouse, Pullman, WA 99164. In Idaho, production and distribution of foundation seed are under the direction of the Idaho Crop Improvement Assoc., Inc., 1641 S. Curtis Rd., Boise, ID. Publ. in Crop Sci. 35:943. 1995.
