‘ND Pegasus’, a new great northern bean with upright plant architecture and high seed yield

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.Abbreviations: NDSU, North Dakota State University.

Registration of ‘Eiger’ great northern bean

“…et Magnus) Lams.‐Scrib]. Osorno et al, 2020 provided a recent summary of the origin, production, and breeding objectives used to improve great northern bean in the United States. As a market class, great northern bean is minor but of local importance in certain production areas (Vandemark et al, 2014).…”

“…Breeding efforts led to the development of upright type II cultivars such as ‘Matterhorn’ (Kelly et al, 1999) and ‘Powderhorn’ (Kelly et al, 2014). In addition, great northern breeding lines from MSU have been used by breeders in other states to develop cultivars such as ‘ND Pegasus’ (Osorno et al., 2020) and ‘Panhandle Pride’ (Urrea et al, 2019).…”
