“…Park and Maga (1999) verified that darkening is accelerated by high grain humidity and light incidence. Ribeiro et al (2004) reported a differential response of cultivars to years and growing seasons and reported that grain darkening is favored in rainy seasons.…”

ABSTRACT. The maintenance of the light color of the grains of carioca beans is a requirement for the development of new cultivars of common beans because it enables the storage of grains for long periods so that they may be traded at a proper opportunity. Crosses of cultivar BRSMG Madrepérola, which presents slow grain darkening, were made to 10 elite lines presenting normal darkening to obtain information about the genetic control of the trait and estimates of phenotypic and genotypic parameters. Progenies at the tegument generations F 3 and F 4 and their parents were evaluated at the locations of Santo Antônio de Goiás and Ponta Grossa at 71, 106, and 155 days of storage for seed-coat darkening using a rank of scores ranging from 1 (very light colored grains) to 5 (very dark colored grains). Genotypic and phenotypic variances and broad-sense heritabilities were estimated for each population. The segregation ratios were subjected to the chi-square test to establish the genetic control. Some populations did not present consistent patterns of genetic control, while others presented monogenic or double-recessive digenic segregation, indicating that the trait is controlled by few genes. Six segregant populations were identified 6487 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 13 (3): 6486-6496 (2014) Seed-coat darkening of carioca beans with both low means for darkening and high expected gain under selection. Despite the strong environmental influence on the expression of the traits and the occurrence of the genotype by environment interaction, the estimates of genotypic and phenotypic parameters indicate the possibility of successful selection to develop lines with slow seed-coat darkening.

“…High SMC and/or high relative humidity in the storage environment have been identified by other researchers as major factors responsible for the deterioration of quality traits including colour of other species of bean. In pinto beans (P. vulgaris) seeds with 10% added moisture have greater colour change (decrease in Hunter L * values and increase in a * values) than control seeds or seeds with 5% added moisture (Park & Maga, 1999). Increases in postharvest colour darkening in Rwandan dry beans positively relate to increase in water activity (a w ) across a range of storage temperatures (Edmister et al, 1990).…”

“…In other legumes there is some evidence that temperature, relative humidity (RH), seed moisture content (SMC) and light are the main factors that affect the stability of seed colour during storage (Hughes & Sandsted, 1975;Nordstorm & Sistrunk, 1977;Nozzolillo & De Bezada, 1984;Park & Maga, 1999). High temperature (!24 C) and high RH (!80%) accelerated darkening in kidney beans (Phaseolus vulgaris L.) while beans stored at low temperature (1 C) and RH (30%) retained their original colour for one year (Hughes & Sandsted, 1975).…”

a b s t r a c tFaba beans cv. Fiesta with seed moisture content (SMC) modified to 8, 10, 12 and 14% were packed in polyethylene lined aluminium foil bags and stored at 5,15, 20, 25, 30, 37, 45, 50 or 60 C (AE 2 C) for one year. Samples were analysed for moisture content and seed coat (testa) colour over the storage period using a chroma meter. A continuous increase in L * and b * values was found in all samples with the passage of time whereas a * values first increased and then decreased in samples stored at relatively high temperatures (! 37 C). The initial beige testa colour changed to light brown, dark reddish-brown or almost black depending on storage conditions. The higher the temperature and SMC the faster the rate of change in colour (6E ab * values). Seeds with 8% SMC had more stable testa colour compared to seeds with higher SMC.Exposure to artificial light (350 m mol m À2 s À1 ) substantially accelerated the colour darkening. Cotyledons stored at 37 AE 2 C also darkened with the storage time. A loss in total free phenolics, total tannins and proanthocyanidins was found with increased darkness of testa and cotyledons during storage.

“…Consumers use certain seed physical traits such as color, brightness, and texture as indicators of seed quality and freshness (Wassimi et al, 1982; Park and Maga, 1999). For example, pinto bean seeds with a light cream background, along with a bright yellow corona color, are perceived by many consumers as fresh, high‐quality beans (Muharrem et al, 2001).…”

‘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.
