Resumo Introdução: Os produtos de tabaco aquecido (HTP) têm ganhado popularidade nos últimos anos. No entanto, tem-se questionado sobre os danos que provocam na saúde, em especial aos impactos decorrentes da exposição a suas emissões. O objetivo deste estudo é avaliar o impacto do uso de HTPs em ambientes internos/fechados na qualidade do ar e/ou na saúde das pessoas expostas passivamente, por meio de uma revisão sistemática de estudos originais. Métodos: Realizou-se busca bibliográfica nas bases de dados Medical Literature Analysis and Retrieval Sistem (MEDLINE), Excerpta Medica Database (EMBASE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e SCOPUS. As etapas de seleção, extração dos dados e avaliação do risco de viés dos estudos foi realizada em dupla, de forma independente, e as divergências foram resolvidas por consenso. Resultados: Foram selecionados 21 estudos, incluídos nesta revisão. Os resultados indicam que os produtos de tabaco aquecido são fonte de poluição ambiental decorrente da emissão de material particulado. Conclusão: Os produtos de tabaco aquecido produzem emissões que podem expor as pessoas às substâncias tóxicas emitidas no ambiente fechado, assim como outros produtos de tabaco.

Abstract Introduction: Heated tobacco products (HTP) have gained popularity in recent years. However, questions have been raised about the damage they cause to health, especially the impacts resulting from exposure to their emissions. This study aims to evaluate the impact of the use of HTPs indoors on air quality and/or the health of passively exposed people, through a systematic review of original studies. Methods: A bibliographic search was carried out in the Medical Literature Analysis and Retrieval System (MEDLINE), Excerpta Medica Database (EMBASE), Latin American and Caribbean Health Sciences (LILACS) and SCOPUS databases. Results: 21 studies were selected and included in this review. The results indicate that heated tobacco products are a source of environmental pollution due to the emission of particulate matter. The stages of selection, data extraction and risk of bias assessment of the studies were performed in pairs, independently, and disagreements were resolved by consensus. Conclusion: Heated tobacco products produce emissions that can expose people to toxic substances emitted indoors, just like other tobacco products.

Resumo Objetivo Investigar e analisar a legislação atual, experiências e cenários existentes sobre a restrição da venda de produtos derivados de tabaco apenas em tabacarias, a fim de elaborar recomendações para o poder público, visando fortalecer a Política Nacional de Controle do Tabaco. Método Revisão de escopo conduzida de acordo com a metodologia Joanna Briggs Institute, com base na estrutura do PRISMA Checklist and Explanation. As bases de dados utilizadas foram Biblioteca Virtual em Saúde (BVS), Epistemonikos, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Medical Literature Analysis and Retrieval Sistem (MEDLINE) via Pubmed, Biblioteca eletrônica SCIELO, SCOPUS, Web of Science, Biblioteca Digital de Teses e Dissertações (BDTD) e Johns Hopkins. Dados coletados em março de 2021, considerando os estudos publicados no período de janeiro de 2005 a dezembro de 2020. Foram incluídos artigos e pesquisas acadêmicas desenvolvidas no cenário brasileiro e publicadas entre janeiro de 1994 e dezembro de 2020. Resultados Os bairros de baixa renda geralmente têm uma densidade maior de pontos de venda de tabaco e apresentam taxas mais altas de uso do tabaco, levando a iniquidades em saúde. Estudos indicam que as crianças têm maior probabilidade de fumar quando vivem ou vão à escola em bairros com alta densidade de varejistas de tabaco. Conclusão Por meio deste estudo, compreende-se que é preciso instituir a venda de produtos derivados de tabaco exclusivamente em tabacarias no Brasil, mas tais estabelecimentos estariam sujeitos a um novo ordenamento jurídico a ser instituído em âmbito nacional.

Abstract Objective To investigate and analyze current legislation, existing experiences and scenarios regarding the restriction of the sale of tobacco products only in tobacconists, in order to prepare recommendations for the public authorities, aiming to strengthen the National Tobacco Control Policy. Method Scope review conducted according to the Joanna Briggs Institute methodology, based on the PRISMA Checklist and Explanation framework. The databases used were the Virtual Health Library (BVS), Epistemonikos, Latin American and Caribbean Health Sciences Literature (LILACS), Medical Literature Analysis and Retrieval System (MEDLINE) via Pubmed, SCIELO electronic library, SCOPUS, Web of Science, Digital Library of Theses and Dissertations (BDTD) and Johns Hopkins. Data collected in March 2021, considering studies published from January 2005 to December 2020. Articles and academic research developed in the Brazilian scenario and published between January 1994 and December 2020 were included. Results Low-income neighborhoods generally have a higher density of tobacco outlets and have higher rates of tobacco use, leading to health inequities. Studies indicate that children are more likely to smoke when they live or go to school in neighborhoods with a high density of tobacco retailers. Conclusion This study shows that it is necessary to set up the sale of tobacco products exclusively in tobacconists in Brazil, but such establishments would be subject to a new legal order to be instituted at the national level.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

Abstract: En | Text: En | PDF: En

SUMMARY Thyroid cancer is the most common endocrine malignancy, and papillary thyroid carcinoma (PTC) is the main subtype. The cribriform morular variant is a histological phenotype of PTC characterized by its relationship with familial adenomatous polyposis (FAP). Description of the case: We report the genetic assessment of a 20-year-old female patient diagnosed with a cribriform-morular variant of PTC and FAP. We aimed to assess the genetic background of the reported patient, looking for variants that would help us explain the predisposition to tumorigenesis. Genomic DNA was extracted from peripheral blood lymphocytes, and whole exome sequencing was performed. We applied an overrepresentation and gene-set enrichment analysis to look for an accumulation of effects of variants in multiple genes at the genome. We found an overrepresentation of single nucleotide variants (SNVs) in extracellular matrix interactions and cell adhesion genes. Underrepresentation of SNVs in genes related to the regulation of autophagy and cell cycle control was also observed. We hypothesize that the package of alterations of our patient may help to explain why she presented colonic manifestations and thyroid cancer. Our findings suggest that multiple variants with minor impact, when considered together, may be helpful to characterize one particular clinical condition.

Resumo Este estudo avaliou o uso de monogenóideos parasitos das brânquias de Sciades herzbergii (Siluriformes/Ariidae) como bioindicadores de qualidade ambiental em ecossistemas estuarinos amazônicos. Os peixes foram capturados nos canais das marés em uma área impactada - IA, próxima ao porto de São Luís, e uma área de referência - RA, no estuário do Caeté, Bragança. A influência do local de captura e sazonalidade na abundância do parasita, variáveis ambientais e dados biométricos dos hospedeiros foram verificados. Um total de 416 espécimes de S. herzbergii foram analisados. O peso e o comprimento total dos peixes da RA foram maiores do que os dos IA. O fator de condição relativo foi influenciado pela sazonalidade. Um total de 4.265 espécimes de monogenóideos das seguintes espécies foram identificados: Chauhanellus boegeri, C. susamlimae, C. velum, Calceostomella herzbergii e Dactylogyridae gen. sp. A abundância parasitária média sazonal de C. susamlimae foi significativamente diferente, com os maiores valores registrados durante a estação seca. A abundância média de C. herzbergii foi influenciada pela sazonalidade e pelo local de captura. Durante o período chuvoso, os índices parasitários na RA foram superiores aos da IA. C. herzbergii é um bioindicador sensível à baixa qualidade da água, principalmente em relação à turbidez da água em estuários amazônicos.

Abstract This study evaluated the use of gill parasitic monogenoideans from Sciades herzbergii (Siluriformes: Ariidae) as bioindicators of environmental quality in Amazonian estuarine ecosystems. Fish were caught in the tidal channels in an impacted area - IA, near the port of São Luís and a reference area - RA, in the Caeté estuary, Bragança. The influence of the capture site and seasonality on parasite abundance, environmental variables and biometric data of hosts were verified. A total of 416 S. herzbergii specimens were analyzed. The weight and total length of fish from the RA were greater than those of the IA. The relative condition factor was influenced by seasonality. A total of 4,265 monogenoidean specimens from the following species were identified: Chauhanellus boegeri, C. susamlimae, C. velum, Calceostomella herzbergii and Dactylogyridae gen. sp. The seasonal mean parasitic abundance of C. susamlimae was significantly different, with the highest values recorded during the dry season. The mean abundance of C. herzbergii was influenced by seasonality and by the capture site. During the rainy period, the parasite indices in the RA were higher than those of IA. C. herzbergii is a bioindicator sensitive to low water quality, especially in relation to water turbidity in Amazon estuaries.

ABSTRACT. The aim of this work was to verify by means of adaptability and stability analyses which genotype of Plinia sp. (jabuticaba tree) is more adapted to orchard conditions, based on the measures of stem growth and primary shoots. During a three-year period, the initial growth of jabuticaba tree genotypes from the native fruit collection of the Experimental Station of the Universidade Tecnológica Federal do Paraná - Câmpus Dois Vizinhos was evaluated. These genotypes included seedlings from forest fragments of the southwestern region of Paraná State and some from Minas Gerais State, Brazil. Analysis of variance (ANOVA) was performed, in a 29 x 3 factorial design, with three replicates in each treatment. Phenotypic adaptability and genotypic stability were evaluated based on the data obtained by the following methods: Eberhart and Russell, Lin and Binns and the AMMI. The analyses were carried out through the computer programs GENES and Stability. The methods that were tested to determine the adaptability and stability of the growth behaviour of the jabuticaba tree did not present consistent patterns in the results. However, the genotype generally referred to as 'Vitorino' was the most suitable for open-air cultivation.

RESUMO O objetivo deste trabalho foi avaliar a aplicação das misturas de maturadores químicos na qualidade tecnológica e produtividade agrícola da cana-de-açúcar . Foi utilizado o delineamento experimental em blocos casualizados arranjados em parcelas sub-subdivididas com 4 blocos, sendo as parcelas principais constituídas pelas variedades de cana-de-açúcar: SP803280 e SP801842. As subparcelas consistiram da aplicação dos seguintes produtos com suas respectivas misturas: controle - ausência de maturador; sulfometurom metil + glifosato; etefon + glifosato; glifosato e compostos de radicais carboxílicos orgânicos + glifosato. As sub-subparcelas foram constituídas de épocas de avaliação: 0; 15 e 30 dias após as aplicações dos produtos. As amostras de cada parcela foram colhidas manualmente e encaminhadas ao laboratório para determinação dos sólidos solúveis Brix (% caldo); teor de sacarose no caldo - Pol (% caldo); Açúcares redutores (AR%); Açúcares redutores totais (ART%); Fibra (%); Pureza (%); Umidade (%) e Açúcar total recuperável ATR (kg t-1). As parcelas foram totalmente colhidas e os colmos despontados para pesagem e para a determinação das características: Rendimento de colmos por hectare (TCH) e Rendimento de açúcar por hectare (TAH). A variedade SP803280 destacou-se como mais responsiva ao uso das misturas de maturadores químicos. Para as características tecnológicas, a mistura sulfometurom metil (0,02 kg ha-1) + glifosato (0,15 L ha-1) apresentou os melhores resultados a partir dos 15 dias após a sua aplicação. As misturas de maturadores químicos não proporcionaram aumentos de produtividade de colmos e açúcar por área.

ABSTRACT The objective of this work was to evaluate the effect of applying mixtures of chemical ripeners on the technological quality and agricultural productivity of sugarcane. The experimental design consisted of randomized blocks arranged in split- split-plots with four blocks, the main plots being constituted by sugarcane varieties SP803280 and SP801842. The subplots consisted of the application of the following products with their respective mixtures: control - absence of ripener; Sulfometrom methyl + glyphosate; ethephon + glyphosate; glyphosate and compounds of organic carboxylic radicals + glyphosate. The sub-subplots were composed of evaluation times: 0; 15 and 30 days after applying the products. Samples from each plot were collected manually and sent to the laboratory for the determination of soluble Brix solids (% broth); Sucrose content in the broth - Pol (% broth); Reducing sugars (RS%); Total reducing sugars (TRS%); Fiber (%); Purity (%); Humidity (%) and Total recoverable sugar TRS (kg t-1). The plots were fully harvested and the stems were taken for weighing and for characteristics determination: Yield per hectare (TCH) and Yield of sugar per hectare (TAH). The SP803280 variety was more responsive to the use of mixtures of chemical ripeners. For the technological characteristics, sulfometurom methyl (0.02 kg ha-1) + glyphosate (0.15 L ha-1) presented the best results from 15 days after application. Mixtures of chemical ripeners did not increase the yields of stalks and sugar per area.

ABSTRACT The effect of additives used in the feed of broilers on anaerobic bio-digestion of poultry litter was evaluated. Four diets were used: NC: negative control; DFM: NC + 500 ppm direct-fed microbials (DFM) containing Bacillus subtilis and Bacillus licheniformis; ENZ: diet formulated with an enzyme blend (20 ppm phytase, 200 ppm protease and 200 ppm xylanase); DFM+E: ENZ + DFM. Substrates for the anaerobic bio-digestion were prepared with litter from each treatment, containing 4 % total solids (TS). These were used in 16 continuous bio-digesters with a 2 kg d−1 load, to determine the production and potential biogas production and composition during an 85-day period. Influent and effluent samples were collected for the amounts of TS and volatile solids (VS), fiber fraction (neutral detergent fiber [NDF], acid detergent fiber [ADF] and lignin), nutrients (N, P and K), and total and thermotolerant coliforms to be determined. For all treatments a reduction in the following effluents was observed as follows: TS (49, 48, 48 and 50 %) VS (70, 54, 55 and 62 %) NDF (91, 90, 95 and 96 %) ADF (89, 88, 93 and 94 %) and lignin (80, 76, 89 and 88 %). The efficiency of the treatment for coliforms in bio-digesters was higher than 90 % in the 85-day period in all treatment groups. There was a reduction in biogas and methane production when DFM (5500 and 4000 mL) and DFM + E (5800 and 4100 mL) were used, compared to treatments NC (6300 mL and 4400) and ENZ (6400 and 4500 mL). The potential production of reduced TS and VS was higher in ENZ (1:00 and 1.74 106 mL kg−1) when compared to NC (0.88 and 1:02 106 mL kg−1), DFM (0.80 and 1:40 106 mL kg−1) and DFM + E (0.88 1:25 and 106 mL kg−1). The additives did not affect the percentage of methane production, and all treatments showed values higher than 70 %. Adding enzymes to the diet of broilers influences the litter characteristics and, as a consequence, increases biogas production. The addition of DFM and DFM + E to broiler diets reduced biogas and methane production.

RESUMO O objetivo deste trabalho foi avaliar o crescimento da planta, os caracteres da produtividade de grãos e a acumulação de cálcio, potássio e magnésio nas folhas e grãos de cultivares de feijão em resposta à concentração de cálcio na solução nutritiva. Dois experimentos foram conduzidos em cultivo fora do solo com solução nutritiva e em ambiente protegido. No primeiro experimento foram avaliadas cinco concentrações de cálcio (1,10; 1,65; 2,20; 2,75 e 3,30 mmol L-1) e três cultivares de feijão (Iraí, BRS Expedito e Carioca). Altas concentrações de cálcio foram testadas no segundo experimento: 2,20; 2,75; 3,30; 3,85; 4,40 e 4,95 mmol L-1 e duas cultivares de feijão (BRS Expedito e Carioca). A massa seca da parte aérea e das raízes, a produtividade de grãos e a acumulação de cálcio nas folhas e grãos foram aumentadas linearmente em plantas de feijão supridas com 2,20 a 4,95 mmol L-1 de cálcio. Altas concentrações de cálcio não reduziram a acumulação de cálcio, potássio e magnésio nas folhas e nos grãos. Plantas de feijão cultivadas com alta concentração de cálcio apresentam maior massa seca de parte aérea e de raízes, alta produtividade de grãos e alta concentração de cálcio nas folhas e nos grãos.

ABSTRACT The objective of this work was to evaluate the plant growth and grain yield characteristics and the accumulation of calcium, potassium and magnesium in the leaves and grains of common bean cultivars grown with different calcium concentrations in the nutrient solution. Two experiments were conducted with nutrient solutions in a soilless system in a greenhouse. In the first experiment, five calcium concentrations (1.10, 1.65, 2.20, 2.75 and 3.30 mmol L-1) and three common bean cultivars (Iraí, BRS Expedito and Carioca) were evaluated. Higher calcium concentrations (2.20, 2.75, 3.30, 3.85, 4.40 and 4.95 mmol L-1) and two common bean cultivars (BRS Expedito and Carioca) were tested in the second experiment. Dry mass of the shoot and root, grain yield and calcium accumulation in the leaves and grains increased linearly in common bean plants supplied with calcium concentrations between 2.20 and 4.95 mmol L-1. The high calcium concentration did not reduce the accumulation of calcium, potassium and magnesium in the leaves and grains. Common bean plants grown with high calcium concentrations present higher dry mass of the shoot and root, high grain yield and high calcium concentration in the leaves and grains.

O objetivo deste trabalho foi avaliar as principais diferenças no controle genético da concentração de ferro em sementes de feijão comum mesoamericano e andino, em gerações precoces, e selecionar recombinantes com alta concentração de ferro nas sementes. Foram obtidas as gerações F1, F1 recíproco, F2, F2 recíproco e de retrocruzamentos (RC11 e RC12), a partir de cruzamentos entre linhagens mesoamericanas (CNFP 10104 x CHC 01-175) e andinas (Cal 96 x Hooter). A expressão de efeito materno significativo foi observada no grupo gênico mesoamericano. A concentração de ferro foi maior no tegumento das sementes de feijão comum mesoamericano (54,61 a 67,92%) e no embrião das sementes de feijão comum andino (69,40 a 73,44%). Alta estimativa de herdabilidade no sentido amplo foi obtida para a concentração de ferro em sementes de feijão comum mesoamericano e andino. Ganhos com a seleção de maior magnitude, de 20,39 a 24,58%, são esperados nas sementes de feijão comum mesoamericano. A concentração de ferro nas sementes de feijão comum apresentou distribuição contínua em F2, o que é característico de herança quantitativa em feijão comum mesoamericano e andino. Recombinantes com alta concentração de ferro nas sementes podem ser selecionados nos híbridos de feijão comum mesoamericano e andino.

The objective of this work was to evaluate the main differences in the genetic control of the iron concentration in Mesoamerican and Andean common bean seeds, in early generations, and to select recombinants with a high iron concentration in the seeds. F1, F1 reciprocal, F2, F2 reciprocal, and backcross (BC11 and BC12) generations were produced by crosses between Mesoamerican (CNFP 10104 x CHC 01-175) and Andean (Cal 96 x Hooter) inbred lines. The expression of significant maternal effect was observed for the Mesoamerican gene pool. Iron concentration was higher in the seed coat of Mesoamerican common bean seeds (54.61 to 67.92%) and in the embryo of Andean common bean seeds (69.40 to 73.44%). High broad-sense heritability was obtained for iron concentration in Mesoamerican and Andean common bean seeds. Gains with the selection of higher magnitude, from 20.39 to 24.58%, are expected in Mesoamerican common bean seeds. Iron concentration in common bean seeds showed a continuous distribution in F2, which is characteristic of quantitative inheritance in Mesoamerican and Andean common bean seeds. Recombinants with high iron concentration in seeds can be selected in both Mesoamerican and Andean common bean hybrids.

O estudo da eficiência no uso de cálcio é inédita em feijão. Portanto, foram objetivos deste trabalho avaliar a variabilidade genética de linhagens de feijão para os caracteres do crescimento da planta e da produtividade de grãos e a acumulação de cálcio nos tecidos da planta em baixa e alta disponibilidade de cálcio e selecionar linhagens de feijão eficientes no uso de cálcio e responsivas a aplicação deste mineral por diferentes índices. Para tanto, 12 linhagens de feijão foram avaliadas em baixa (1,10 mmol L-1) e em alta (3,85 mmol L-1) concentração de cálcio na solução nutritiva. A linhagem L 15 produziu os maiores valores de massa seca de parte aérea, número de vagens e de grãos por planta, número de grãos por vagem e produtividade de grãos em baixa concentração de cálcio. A acumulação de cálcio nos tecidos foi, em média, maior nas folhas, seguidos pelos caules, vagens e grãos. As linhagens L 175 e L 159 possuem alta concentração de cálcio nos grãos (> 1,1 g kg-1 de MS), independente da concentração de cálcio fornecida às plantas. A linhagem L15 é eficiente no uso de cálcio. As linhagens L 221 e L 159 são responsivas à aplicação de cálcio no ambiente radicular.

The study of the calcium use efficiency in common bean is unprecedented. Therefore, the objectives of this work were to evaluate the genetic variability of common bean lines for plant growth and grain yield characters, the calcium accumulation in different plant tissues at low and high calcium availabilities, and to select common bean lines with high calcium use efficiency and responsive to the calcium application by different indices. Twelve common bean lines were supplied with a nutrient solution at low (1.10 mmol L-1) and high (3.85 mmol L-1) calcium concentration and were evaluated. The L 15 line reached the higher values of dry mass of shoot, number of pods and grains per plant, number of grains per pod and grain yield at the low calcium concentration. Calcium accumulation in tissues was, on average, higher in leaves, followed by stems, pods and grains. The L 175 and L 159 lines have higher calcium concentration in grains (> 1.1 g kg-1 MS), regardless of the calcium concentration supplied to plants. The L15 line is efficient in calcium use. The L 221 and L 159 lines are responsive to the calcium application in the rooting medium.

O cultivo de feijão de grãos especiais ainda é restrito no Brasil. Portanto, os objetivos foram: i) avaliar os efeitos da interação linhagem x ambiente nos caracteres que controlam o desempenho agronômico e o tempo de cozimento em linhagens de feijão de grãos especiais e ii) identificar linhagens de alto desempenho agronômico e de reduzido tempo de cozimento. Para isso, 29 linhagens de feijão de grãos especiais foram avaliadas em diferentes locais, anos e épocas de cultivo. Interação linhagem x ambiente significativa foi observada para todos os caracteres avaliados. As linhagens Light Red Kidney, Red Kanner, Montcalm, Chinock e BRS Radiante apresentaram produtividade de grãos similar nos quatro ambientes. As linhagens avaliadas possuem ciclo semi-precoce ou precoce e têm características morfológicas desejáveis. Os seguintes valores de claridade de tegumento de grãos foram obtidos para feijão branco (72,85 a 82,25), rajado (33,06 a 62,57), vermelho (24,51 a 43,69), verde (57,01 a 62,36) e rosa (49,95 a 55,60). O tempo de cozimento variou de 14 min e 38 seg a 36 min e 21 seg. As linhagens de feijão de grãos especiais de tegumento vermelho (Light Red Kidney, Red Kanner, Montcalm e Chinock) e de tegumento rajado (BRS Radiante) apresentam alto desempenho agronômico e reduzido tempo de cozimento nas condições avaliadas.

The cultivation of the special-grain bean is still limited in Brazil. The objectives here therefore, were: i) to evaluate the effects of the interaction of line and environment on the characteristics that control the agronomic performance and cooking time in special-grain beans lines, and ii) to identify those lines having a high agronomic performance and reduced cooking time. To do this, 29 special-grain beans lines were evaluated for different locations, years and growing seasons. Significant interaction of line and environment was observed for all the traits evaluated. The Light Red Kidney, Red Kanner, Montcalm, Chinock and BRS Radiante lines showed a similar grain yield for the four environments. The tested lines have a semi-early or early cycle and desirable morphological characteristics. The following values for the clarity of the grain tegument were obtained for white beans (72.85 to 82.25), cranberry (33.06 to 62.57), red (24.51 to 43.69), green (57.01 to 62.36) and pink (49.95 to 55.60). Cooking time varied from 14 min and 38 sec to 36 min and 21 sec. The special-grain beans lines of red tegument (Light Red Kidney, Red Kanner, Montcalm and Chinock) and cranberry (BRS Radiante) show high agronomic performance and reduced cooking time under the evaluated conditions.

O objetivo deste trabalho foi avaliar a variabilidade genética de linhagens de feijão para ciclo, massa de 100 grãos, produtividade de grãos, tempo de cozimento e concentração de cálcio e ferro nos grãos. Vinte e quatro linhagens de feijão foram avaliadas em dois ciclos de cultura (2010 e 2011). O índice ¯Z foi usado para a seleção de linhagens superiores, para a maioria dos caracteres. As linhagens DF 06-19, DF 06-03, DF 06-17, DF 06-20, DF 06-11, DF 06-14, DF 06-01, DF 06-08, DF 06-22 e DF 06-04 apresentaram alta produtividade de grãos. Todas as linhagens foram de ciclo semiprecoce e de rápido cozimento. As linhagens DF 06-08 e DF 06-23 apresentaram alta concentração de cálcio nos grãos (>1,4 g kg-1 de matéria seca - MS), e as linhagens DF 06-09, DF 06-03, DF 06-04 e DF 06-06 apresentaram alta concentração de ferro nos grãos (>0,95 g kg-1 de MS), nos dois anos agrícolas. As linhagens do grupo carioca DF 06-09 e DF 06-03 apresentam alto desempenho agronômico e alta concentração de ferro nos grãos. As linhagens do grupo preto DF 06-17 e DF 06-08 apresentam alto desempenho agronômico e alta concentração de cálcio nos grãos. A seleção das linhagens DF 06-09, DF 06-03, DF 06-17 e DF 06-08 é recomendada.

The objective of this work was to evaluate the genetic variability of common bean lines for cycle, weight of 100 grains, grain yield, cooking time, and grain calcium and iron concentrations. Twenty-four common bean lines were evaluated in two crop cycles (2010 and 2011). The ¯Z index was used for the selection of superior lines for most of the traits. The DF 06-19, DF 06-03, DF 06-17, DF 06-20, DF 06-11, DF 06-14, DF 06-01, DF 06-08, DF 06-22, and DF 06-04 lines showed high grain yield. All lines were of semi-early cycle and of fast cooking. The DF 06-08 and DF 06-23 lines showed high calcium concentration in grains (>1.4 g kg-1 dry matter - DM), and the DF 06-09, DF 06-03, DF 06-04, and DF 06-06 lines presented high iron concentration in grains (>0.95 g kg-1 DM) in the two crop cycles. The DF 06-09 and DF 06-03 carioca lines present high agronomic performance and high iron concentration in grains. The DF 06-17 and DF 06-08 black lines present high agronomic performance and high calcium concentration in grains. The selection of the DF 06-09, DF 06-03, DF 06-17, and DF 06-08 lines is recommended.
