Interpretive Summary: Eldorado is a high yielding pinto bean released in 2012. It has potential to be adopted by bean growers in Michigan and in the Western U.S. because of its favorable combination of traits. Eldorado combines exceptional yield potential and upright plant architecture with full-season maturity in the pinto seed type. Its upright growth and resistance to lodging make it suitable for direct harvest under narrow-row production systems. Over 5 years of studies, Eldorado also showed 12-42% lower incidence of white mold than other pinto bean cultivars. Eldorado possesses resistance to rust, virus, and anthracnose. Eldorado has a large, mottled, dry-bean seed with acceptable dry and canned seed quality.
Technical Abstract: ‘Eldorado’ (Reg. No. CV-302, PI 665012) pinto bean (Phaseolus vulgaris L.), which was developed by Michigan State University AgBioResearch, was released in 2012 as an upright, full-season,disease-resistant cultivar. Eldorado, tested as MSU breeding line P07863, was developed using the single-seed-descent breeding method to the F4 generation followed by pedigree selection for disease, agronomic, and quality traits. In 5 yr of fi eld trials, Eldorado yielded 3364 kg ha-1, fl owered in 42 d, and matured in 98 d. Plants averaged 53 cm in height, with a lodging-resistance score of 1.9 and a seed size of 43 g 100 seed-1. Eldorado combines exceptional yield potential and erect architecture with full-season maturity in the pinto seed type. Eldorado has resistance to lodging and high pod placement within the plant structure, making it suitable for direct harvest under narrow-row production systems. The upright architecture also contributes to avoidance of white mold [caused by Sclerotinia sclerotiorum (Lib.) de Bary], a disease intensifi ed by narrow-row production systems. In irrigated trials designed to promote the development of white mold disease, Eldorado had 30% incidence over 5 yr compared with other pinto cultivars that had from 42 to 72% white mold incidence. Eldorado possesses resistance to specifi c races of rust, virus, and anthracnose. Eldorado has a large, mottled, dry-bean seed that meets industry standards for packaging and canning quality in the pinto bean seed class.
