Abstract

Abstract : 'ND‐Palomino' (PVP no. 201700085, Reg. No. CV‐319, PI 680582) is a new slow‐darkening pinto bean ( Phaseolus vulgaris L.) cultivar jointly developed by the USDA‐ARS and North Dakota State University and released by the North Dakota Agricultural Experiment Station. Pinto beans are prone to seed darkening caused by delayed harvest and/or poor storage conditions. Growers are penalized by receiving a discounted price while creating marketing issues for processors and packers. In addition to the slow‐darkening trait, ND‐Palomino has shown competitive agronomic performance comparable with other pinto cultivars commonly grown in the region. Averaged across 31 common environments, seed yield of ND‐Palomino (2965 kg ha −1 ) was statistically similar to that of 'Stampede' (2877 kg ha −1 ), and across 33 common environments, seed yield of ND‐Palomino (2755 kg ha −1 ) was statistically similar to that of 'Lariat' (2796 kg ha −1 ). However, across 34 common environments, seed yield of 'Windbreaker' (3038 kg ha −1 ) and 'La Paz' (3042 kg ha −1 ) was ∼200 kg ha −1 higher than that of ND‐Palomino (2819 kg ha −1 ). Still, any small difference would be compensated for or even exceeded by not having discounted prices due to poor seed quality. Moreover, seed yield of ND‐Palomino is significantly higher than the original sources of the sd gene, which shows genetic progress for improving seed yield within this market class. Other traits of agronomic or economic importance are within acceptable commercial ranges for pinto beans.
