‘Rosetta’ pink bean ( Phaseolus vulgaris L.) (Reg. No. CV‐301, PI 665011), developed by Michigan State University AgBioResearch, was released in 2012 as an upright, short vine, midseason, disease‐resistant bean cultivar. Rosetta was developed with the pedigree breeding method to the F 4 generation followed by pure line selection for disease, agronomic, and quality traits. In 4 yr of field trials, Rosetta yielded 2800 kg ha −1 , flowered in 43 d, and matured in 95 d. Plants averaged 54 cm in height, with a lodging resistance score of 1.8 and seed size of 36 g 100 seed −1 . Rosetta has resistance to lodging, and its high pod placement within the plant structure makes 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 aggravated by narrow‐row production systems. Rosetta does not exhibit the stem breakage problem inherent with the ‘Sedona’ pink cultivar. Rosetta has a bright pink seed that retains its color in storage and meets industry standards for packaging and canning quality in the pink bean seed class.
