Broadening the Genetic Base and Introgression of Resistance to Multiple Diseases in Pinto Bean Grant uri icon

Overview

abstract

  • Of approximately a dozen different market classes of dry bean (Phaseolus vulgaris L.) grown in the U.S. and North America, the pinto bean is by far the most important, occupying more than half of the acreage. Pinto bean cultivars are highly susceptible to diseases such as Beet curly top virus, Bean common mosaic virus, Bean common mosaic necrosis virus, common bacterial blight, rust, and white mold. High level of cultivar resistance to these diseases would minimize yield losses, reduce pesticide use and production cost, and facilitate integrated disease management and production of pathogen-free seed. We aim to (1) assess the reaction of different pinto bean cultivars grown in the U.S. to each of the above six diseases, (2) identify resistant germplasm of diverse genetic origins, and (3) introgress and pyramid resistance to the six diseases into broadly adapted pinto bean breeding lines and cultivars.
