Interpretive Summary: Small red bean production is concentrated in Michigan and Washington state. Cayenne is a new small red bean cultivar developed specifically for production in these two states. It possesses resistance to BCMV potyvirus, which plagues production in WA, resistance to bean rust, which is a problematic fungal disease in MI, and partial resistance to white mold, that benefits production in both regions. Cayenne yields more than the industry standard while maintaining the canning quality and agronomic traits (moderate maturiy, upright architecture) of the check. This cultivar will benefit growers in MI and WA by providing a higher yielding cultivar with improved disease resistance.
Technical Abstract: ‘Cayenne’ small red bean (Phaseolus vulgaris L.), developed by Michigan State University AgBioResearch, was released in 2017 as an upright, full-season cultivar that possesses excellent canning quality, tolerance to common bacterial blight [CBB; caused by Xanthomonas axonopodis pv. phaseoli (Smith) Dye], and white mold [caused by Sclerotinia sclerotiorum (Lib.) de Bary]. Cayenne was developed using pedigree breeding method to the F4 generation followed by pure line selection for disease, agronomic and quality traits. In 5-yr of field trials, Cayenne yielded 3350 kg ha-1, flowered in 45 d and matured in 97 d on average. Plants averaged 52 cm in height, with lodging resistance score of 1.8 and seed weight of 36.1g 100 seed-1. Cayenne combines high yield potential with resistance to lodging, high pod placement, and plant structure that makes 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 by narrow row production systems. Cayenne is partially resistant to local isolates of CBB, is resistant to strain NL 3 of Bean common mosaic necrosis virus (BCMNV) but is susceptible to race 73 of anthracnose and to race 22:2 of bean rust. Cayenne produces seed that meets industry standards for packaging and was rated highest in overall canned bean quality in the small red bean seed class.
