A new pink bean cultivar with improved agronomic performance: Registration of ‘ND Rosalind’

Abstract

‘ND Rosalind’ (Reg. no. CV-364, PI 705585) is a new pink bean (Phaseolus vulgaris L.) cultivar developed by the Dry Edible Bean Breeding Program at North Dakota State University and released by the North Dakota Agricultural Experiment Station. ND Rosalind was developed using a modified pedigree breeding method to the F_4:5 generation followed by pure line selection for disease, agronomic, and quality traits. Between 2017 and 2023, ND Rosalind was tested across more than 11 environments in North Dakota, where seed yield was significantly higher than other pink bean cultivars such as ‘Magnolia’, ‘Rosetta’, and ‘Sedona’ (23%, 12%, and 16% respectively). ND Rosalind is resistant to both the Bean common mosaic virus and Bean common mosaic necrotic virus and has intermediate resistance to common bacterial blight. ND Rosalind has desirable upright architecture (Type IIa). Under North Dakota conditions, ND Rosalind shows an average plant height of 56 cm, has a 100-seed weight of 30.9 g, and matures in ∼101 days. ND Rosalind has a bright seed color and an acceptable canning quality. Other traits of agronomic and economic importance are within acceptable commercial ranges.
