Interpretive Summary: Pinto beans are the largest per-capita class of dry beans in the US and production acreage continues to grow. Producers need cultivars that show resistance to common diseases and that yield seeds with good storage and processing qualities. We used selective breeding methods to develop ‘Charro’ pinto bean as a new cultivar with improved disease, agronomic, and quality traits. Charro combines high yield potential with upright plant architecture, the latter contributing to avoidance of white mold disease. Charro also exhibits resistance to bean common mosaic necrosis virus. This pinto bean cultivar will provide producers with a new planting option for this highly valued type of dry bean.

Technical Abstract: ‘Charro’ pinto bean (Phaseolus vulgaris L.) (Reg. no. CV-341, PI 695318), developed by Michigan State University AgBioResearch, was released in 2020 as a high-yielding, upright, full-season cultivar with excellent canning quality. Charro was developed using the pedigree breeding method to the F4 generation followed by pure line selection for disease, agronomic, and quality traits. In 4 yr of field trials, Charro yielded 3,230 kg ha-1 at 17 locations in mid-Michigan, flowered in 46 d, and matured in 97 d on average. Plants averaged 52 cm in height, with a lodging resistance score of 1.6 and seed weight of 41.2 g per 100 seed. Charro combines high yield potential and erect architecture with full-season maturity in a pinto seed type. Charro 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, a disease that is intensified under narrow-row production systems. Charro exhibits the top necrosis reaction to strain NL 3 of Bean common mosaic necrosis virus. Charro produces seed that meets industry standards for export and packaging, and canning quality was rated excellent for the pinto bean seed class.
