'ND Redbarn' (PVP. no. 202300271; Reg. no. CV‐357, PI 703021) is a new dark red kidney bean (Phaseolus vulgaris L.) cultivar developed by the Dry Edible Bean Breeding Program at North Dakota State University and released in 2023 by the North Dakota Agricultural Experiment Station. Compared to other market classes, kidney beans usually command higher prices. However, kidney beans are less productive than other market classes. Minnesota is the largest dark red kidney bean producer in the United States, accounting for ∼90% of the total production in 2022. ND Redbarn was released based on its good adaptation to this region, higher seed yield, large seed size, and desirable seed shape characteristics. Between 2012 and 2021, ND Redbarn was tested across 16 environments in Minnesota, where seed yield was significantly higher than commercial checks 'Montcalm', 'Red Hawk', and 'Talon' (14%, 27%, and 9%, respectively) and comparable with 'Dynasty'. ND Redbarn is resistant to Bean common mosaic virus and has intermediate resistance to common bacterial blight. ND Redbarn exhibits higher field tolerance to the root rot fungal complex infection compared to Montcalm, Red Hawk, and Talon, and is similar to Dynasty. ND Redbarn has shown higher levels of tolerance to white mold than Montcalm and Red Hawk. Under Minnesota environments, ND Redbarn shows an average plant height of 51 cm, has a 100‐seed weight of 50.4 g, and matures in approximately 99 days. The canning quality for Redbarn is within acceptable commercial ranges. Core Ideas: Dark red kidney bean is the most predominant market class in Minnesota, which accounts for ∼90% of the total US production.Dark red kidney beans are known to be less productive than other bean market classes, but they respond extremely well to good agronomic management.Strict industry and consumer requirements in terms of visual seed quality for kidney beans hinders genetic progress for this market class.Improvements in dark red kidney bean productivity, disease resistance, and size and shape have been accomplished in the new cultivar ND Redbarn.
