Registration of ‘Yellowstone’ yellow bean

Abstract

Abstract‘Yellowstone’ yellow bean (Phaseolus vulgaris L.) (Reg. no. CV‐340, PI 695270), developed by Michigan State University AgBioResearch, was released in 2020 as a determinate, virus‐resistant cultivar with highly desirable vibrant dry seed coat color. Yellowstone was developed using the pedigree breeding method to the F3 generation followed by pure line selection for disease, agronomic, and quality traits. In 4 yr of field trials, Yellowstone yielded 2,902 kg ha−1, flowered in 41 d, and matured in 94 d on average. Plants averaged 47 cm in height, with a lodging resistance score of 1.8 and seed weight of 46 g per 100 seed. Yellowstone is well adapted to growing conditions in Michigan and produces seed with an intense yellow seed coat color under local conditions. Yellowstone is resistant to lodging, which also contributes to the avoidance of white mold. Yellowstone exhibits the top necrosis reaction to strain NL 3 of Bean common mosaic necrosis virus conditioned by the I gene. Yellowstone produces seed that exceeds industry standards for export and packaging, and canning quality was rated acceptable for the yellow bean seed class.
