Abstract

Abstract: 'ND Pegasus' great northern bean (PVP‐201900176, Reg. no. CV‐328, PI 690448) is a new cultivar developed by the dry bean breeding program at North Dakota State University and released by the North Dakota Agricultural Experiment Station. Great northern bean is a market class of significant economic importance in the United States. In North Dakota especially, biotic and abiotic stresses are the main factors for seed yield reductions. Between 2013 and 2018, ND Pegasus, along with great northern cultivars commonly grown in the region, was tested across more than 35 environments in North Dakota and other states. Seed yield of ND Pegasus was significantly higher by 560, 414, and 571 kg ha ‐1 compared with 'Matterhorn', 'Aries', and 'Powderhorn', respectively. However, seed yield of ND Pegasus and 'Taurus' were similar. ND Pegasus has an excellent upright architecture that improves the efficiency of direct harvest. Based on greenhouse and DNA marker data, ND Pegasus is resistant to Bean common mosaic virus and has improved resistance to white mold. ND Pegasus has excellent seed quality (color, shape, and size) and is larger than most commercial cultivars commonly grown in the region. ND Pegasus has acceptable canning quality based on some pilot testing. The average plant height of ND Pegasus is 71 cm, and 100‐seed weight 36.8 g. It matures in approximately 103 d. Other agronomic traits of economic importance are within commercial acceptable ranges.
