“…No comércio de grãos de feijão, atributos qualitativos como menor tempo para o cozimento, alta capacidade de hidratação e qualidade proteica são preferidos pelos consumidores (BURATTO et al, 2009;COELHO et al, 2008;LEMOS, 2010;MINGOTTE et al, 2013;OLIVEIRA et al, 2013;PERINA et al, 2010;RAMOS JUNIOR et al, 2005a). No entanto, durante o seu armazenamento alguns destes atributos são alterados, e os prejuízos são expressos principalmente pelo aumento do tempo de cozimento e escurecimento do tegumento, o que leva perda de valor comercial (LIMA et al, 2014).…”

RESUMO: Os consumidores de feijão são exigentes quanto às características grão, demandando baixo tempo de cozimento, alta capacidade de hidratação e qualidade proteica. Entretanto esses atributos durante o armazenamento podem ser alterados, levando à perda de qualidade. O objetivo deste trabalho foi avaliar os atributos qualitativos de cultivares de feijoeiro do grupo comercial carioca durante o armazenamento. O delineamento utilizado foi inteiramente casualizado, em esquema fatorial 13x3, constituído por cultivares de feijoeiro (Pérola, BRSMG Majestoso, BRS Estilo, BRSMG Madrepérola, IPR Campos Gerais, IPR Tangará, IPR Andorinha, IPR 139, IAC Imperador, IAC Formoso, IAC Alvorada, IAC Milênio e Bola Cheia) e três tempos de armazenamento (grãos recém colhidos, com quatro e oito meses após a colheita), com quatro repetições. Foram avaliados a coloração do tegumento, teor de proteína bruta, tempo de cozimento, relação de hidratação e tempo para máxima hidratação. O período de armazenamento não altera significativamente os atributos qualitativos dos grãos, mantendo a maioria das características essenciais ao mercado consumidor. A BRSMG Madre pérola não apresentou alteração na cor do tegumento, e o menor tempo de cozimento foi apresentado pela cultivar IPR Andorinha. O escurecimento dos grãos de feijão não está associado com o aumento do tempo de cozimento. Todas as cultivares apresentam resultado satisfatório para o tempo de máxima hidratação e a relação de hidratação.Palavras chave: Phaseolus vulgaris. Genótipos. Tempo de cozimento.

EFFECT OF STORAGE ON BEAN CULTIVARS FOR COMMERCIALIZATION ABSTRACT:Beanconsumers are demanding about the grain characteristics, requiring low cooking time, high hydration capacity and, protein quality. However these attributes during storage can be altered, resulting in loss of quality The objective of this study was to evaluate the qualitative attributes of common bean cultivars of "carioca" commercial group during storage. The design was completely randomized in a factorial scheme 13x3, consisting of bean cultivars (Pérola, BRSMG Majestoso, BRS Estilo, BRSMG Madrepérola, IPR Campos Gerais, IPR Tangará, IPR Andorinha, IPR 139, IAC Imperador, IAC Formoso, IAC Alvorada,

Iron and zinc deficiencies in humans can cause serious health problems. Increasing the iron (IC) and zinc (ZC) concentrations in common bean (Phaseolus vulgaris L.) grains using genetic breeding can be an effective strategy to prevent these problems. Thus, the aims of this study were i) to investigate the importance of genetic, environmental, and genotype-by-environment interaction effects on IC and ZC in common bean grains; ii) to select cultivars that have high mean values and phenotypic stability for IC and ZC, as well as high protein concentration (PC), high yield, and standard commercial grain quality; and iii) to investigate whether there is a genetic relationship between these traits. A total of 34 cultivars were evaluated in 19 different environments. Genetic variability was observed among the genotypes for all traits. For IC and ZC, the environmental effect represented most of the total variation (63% and 65%, respectively), and the effect of the G × E interaction was 18% for IC and 15% for ZC. The genetic correlations between IC, ZC, and PC were positive, indicating that the selection of one of these traits resulted in gains for the other. The genetic correlations between IC or ZC with yield or 100-grain weight were low or intermediate, but negative, indicating that it is important to evaluate these traits at all stages of breeding programs that focus on developing cultivars with high IC and ZC. The cultivar BRS Sublime, with the carioca grain type, combined high IC, ZC, and PC, high yield, and grains of commercial size.

Bean cultivation serves as a crucial food source for humans, supplying essential nutrients like proteins, vitamins, and iron. Hence, its significance is paramount, particularly for the Brazilian populace, where it's consumed across all regions of the country. This study evaluates the nutritional content of various landrace bean genotypes cultivated in Alta Floresta, Mato Grosso, Brazil, located in the southern Amazon region. By analyzing nine samples from local smallholder farmers, the study determines the levels of essential nutrients such as iron, zinc, calcium, magnesium, phosphorus, potassium, sulfur, boron, copper, and manganese. Results indicate significant variability in nutrient content across different genotypes, with iron levels ranging from 36 to 78 mg/kg and zinc levels from 29 to 48 mg/kg. These findings highlight the potential of landrace beans to enhance dietary nutrient intake, particularly in regions where food security is a concern. The study underscores the importance of preserving genetic diversity in beans, which can be leveraged for crop improvement programs aimed at boosting nutritional quality. Additionally, this research is crucial for promoting sustainable agricultural practices and ensuring food security in the southern Amazon region.
