This study assessed the impact of phytoremediation on reducing the residual concentration of metolachlor in soil treated with doses of 530.7 and 1061.4 g/ha and its effect on microbial biodiversity in contaminated areas. For the plant species Avena sativa and Medicago sativa, a significant efficacy of 54.5 and 36.4% was observed in the dissipation of the herbicide, especially at higher doses. Although metolachlor application reduced soil microbial biodiversity, phytoremediating plants, especially M. sativa, promoted greater richness and distribution of microbial species, mitigating the negative effects of the herbicide. Principal component analysis revealed the influence of these plants and metolachlor on the composition of the microbial community. These results highlight the importance of phytoremediation in promoting soil biodiversity and reducing herbicide contamination, providing crucial insights for remediation strategies in contaminated areas.

The demand for high-quality vegetable seeds and the production of vigorous seedlings has increased in recent years, as these characteristics are determining factors of production success. Vegetables are growing in national importance, and kale stands out as an important source of income for small farmers. The objective of this study was to adapt the traditional accelerated aging test methodology with a saturated NaCl solution of kale seeds and evaluate the enzymatic activity after the vigour test. Six batches of kale seeds were used, and the moisture content, weight of one thousand seeds, first germination count, germination, germination speed index, emergence, initial stand, and emergence velocity index were determined. In the accelerated ageing test, the seeds were submitted to the traditional accelerated ageing test method and the accelerated ageing test method with a saturated NaCl solution for ageing periods of 0, 24, 48, 72, and 96 hours. Electrophoretic analysis of superoxide dismutase (SOD), catalase (CAT), and alcohol dehydrogenase (ADH) isoenzymes was also performed. The accelerated ageing test, using the traditional method for 72 hours at 41 °C, is adequate for evaluating the physiological potential of kale seeds. The isoenzymatic analyses of SOD, CAT, and ADH demonstrate that the biochemical markers are efficient at differentiating kale seeds after accelerated ageing. A demanda por sementes de hortaliças com alta qualidade e a obtenção de mudas vigorosas tem aumentado nos últimos anos, pois estas características constituem fatores determinantes do êxito da produção. As hortaliças têm uma importância nacional crescente, dentre elas se destaca a couve, por ser importante fonte de renda para pequenos agricultores. Objetivou-se adequar a metodologia do teste de envelhecimento acelerado tradicional e com solução saturada de NaCl em sementes de couve e avaliar a atividade enzimática após o teste de vigor. Foram utilizados seis lotes de sementes de couve e determinou-se o grau de umidade, peso de mil sementes, primeira contagem de germinação, germinação, índice de velocidade de germinação, emergência, estande inicial e índice de velocidade de emergência. No teste de envelhecimento acelerado, as sementes foram submetidas ao método tradicional e com solução saturada de NaCl, por períodos de 0; 24; 48; 72 e 96 horas. Realizou-se também a análise eletroforética das isoenzimas superóxido dismutase (SOD), catalase (CAT) e álcool desidrogenase (ADH). O teste de envelhecimento acelerado, utilizando o método tradicional na combinação de 72 horas a 41 °C é adequado para avaliar o potencial fisiológico de sementes de couve. As análises isoenzimáticas superóxido dismutase (SOD), catalase (CAT) e álcool desidrogenase (ADH) demonstram que os marcadores bioquímicos são eficientes e promissores na diferenciação de sementes de couve após o envelhecimento acelerado.

Purpose: Changes in lifestyles and consumption have been systematically debated as paths to a more sustainable society. Hence, the sharing of garments is one of the slow fashion strategies to encourage lifestyle changes. Thus, the study aims to investigate how do practitioners and providers perceive the practice of sharing garments in Fortaleza (Brazil). Design/methodology/approach: The research is qualitative and exploratory with data collected through individual and group interviews conducted with practitioners and providers. The content analysis carried out shows some similarities concerning sharing consumption. Research, Practical & Social implications: The study contributes to theory by showing new nuances on how to research about sharing consumption and to practice by providing management insights on which actions are necessary to the practice of clothing consumption... Originality/value: In this study, sharing consumption of second-hand garment is analyzed under the lens of practice theories, which assumes the dynamics between three elements of practice: materials, skills and meanings.

VINASSE ,SEWAGE ,CASSAVA ,SOYBEAN ,SEEDS ,SEED quality - Abstract
This study aimed at evaluating organic by-products vinasse and cassava wastewater on the sanitary and physiological quality of soybean seeds. Sanity tests, phytoalexin induction and physiological qualities were performed, conducted in a completely randomized design. The sanity test was carried out in a 3 × 5 factorial scheme (two by-products: vinasse – V, cassava wastewater – C and the junction between them – V + C, in five concentrations: 0, 25, 50, 75 and 100%), with 8 repetitions/treatment. In the induction of phytoalexin, a factorial scheme (3 × 4) + 1 – two by-products and their junction, was adopted, with 4 concentrations (25, 50, 75 and 100%), plus an additional witness – with 5 repetitions/treatment, and for the physiological qualities 3 × 5 factorial scheme, described above, with four replicates/treatment. Cassava wastewater has large amounts of sugars, which may have favored the development of pathogens in this treatment. Vinasse had the highest capacity of inhibiting the genera Aspergillus, Cladosporium, and Penicillium, which was explained by the positive relationship between its concentrations and the induction of phytoalexin, being the most effective by-product in fungus control, at concentrations of 75 and 100% and without changing the physiological quality of seeds.

- Abstract
The genetic diversity among 46 accessions of physic nut was estimated with Nei and Li’s similarity coefficient based on a collection of 69 random amplified polymorphic DNA (RAPD) sequences and 37 inter-simple sequence repeat (ISSR) polymorphic loci. The genetic distance between accessions ranged from 0.13 to 0.76, with an average genetic distance of 0.21. The most divergent genotypes were 86, 71 and 83. A dendrogram (generated by the unweighted pair group method with arithmetic mean, UPGMA) of the joint data matrix was constructed and presented only two phylogenetic groups, one of which contained only three individuals; the remaining group included 95.6% of the analyzed genotypes. The low genetic diversity measured in this study indicates the need to broaden the genetic base and increase the variability of this species. The amplification products generated by amplification of SSR primers were used to characterize toxicity alleles, and none of the accessions presented patterns characteristic of non-toxic accessions.Keywords: Jatropha curcas, inter-simple sequence repeat (ISSR), random amplified polymorphic DNA (RAPD), microsatellites, toxicityAfrican Journal of Biotechnology Vol. 12(9), pp. 907-913

Com o estímulo à produção e uso de biodiesel, sementes de crambe constituem hoje uma das melhores opções para o fornecimento de matéria-prima, sendo também excelente alternativa para cultivo de outono-inverno visando rotação de culturas. O objeto deste estudo foi avaliar o efeito da combinação de tratamentos de pré-germinação sobre o comportamento de sementes de crambe. A partir de um lote de sementes da cultivar FMS Brilhante, foi proposto o delineamento experimental inteiramente casualizado, em esquema fatorial 2 x 5. O delineamento foi baseado na combinação de duas condições estruturais: sementes com e sem pericarpo, e ambas submetidas a tratamentos pré-germinativos com e sem ácido giberélico, sendo: testemunha (sem tratamento); sementes pré-embebidas em água destilada sem adição de giberelina por 24 horas como controle; e sementes pré- embebidas em solução de ácido giberélico a 4 %, em diferentes concentrações (400; 500 e 600 mg.L -1 ). Determinou-se o teor de água, primeira contagem de germinação, porcentagem de germinação, emergência de plântulas e índice de velocidade de emergência. Diante dos resultados conclui-se que a retirada do pericarpo em sementes de crambe, cultivar FMS Brilhante, acelera a velocidade de germinação, porém, diminui a sua porcentagem final. A pré-embebição em ácido giberélico (400, 500 e 600 mg.L -1 ) por 24 horas proporcionou incrementos na germinação e no vigor das sementes de crambe com pericarpo. Encouraging the production and use of biodiesel, seeds of crambe today constitute one of the best options for the supply of raw material, is also an excellent alternative for autumn-winter crop rotation order. The aim of this study was to evaluate the efficiency of combined pre-germination treatments on the seed behavior of crambe. From a seed sample of FMS Brilhante cultivar, an experimental design completely randomized with a 2 x 5 factorial arrangement was performed. It was formed from combination of two structural conditions, seeds with or without pericarp, and treatments with or without giberelic acid, being: control (no treatment); seeds pre-soaked in distilled water for 24 hours as control; and seeds pre-soaked in gibberellic acid at 4 % at different concentrations (400, 500 and 600 mg.L -1 ). Water content, first count germination, germination, seedling emergence and emergence rate index were determined. From these results it is concluded that removal of the pericarp in seed of crambe, cultivar FMS Brilhante, accelerated the germination rate, however, decrea- sed your final percentage. The pre-soaking in gibberellic acid (400, 500 and 600 mg L -1 ) for 24 hours, increased the germination and seed vigor crambe with pericarp. Como un estímulo a la producción y uso del biodiesel, las semillas de crambe constituyen hoy una de las mejores op- ciones para el suministro de materia prima, también son una excelente alternativa en la rotación de cultivos de otoño- invierno. El objetivo de este estudio fue evaluar la eficiencia de la combinación de tratamientos pre-germinativos sobre el comportamiento de semillas de crambe. A partir de una muestra de semillas del cultivar FMS Brilhante, se propuso un diseño experimental completamente aleatorizado, con un esquema factorial 2 x 5. El diseño se basó en la combinación de dos condiciones estructurales: semillas con y sin pericar- pio, y ambos sometidos a tratamentos pre-germinativos con y sin ácido giberélico, siendo: control (sin tratamiento); se- millas pre-embebidas en agua destilada sin giberelina por 24 horas como control; y semillas pre-embebidas en solución de ácido giberélico a 4 %, en diferentes concentraciones (400; 500 e 600 mg.L -1 ). Se determinó el contenido de agua, primer contaje de germinación y porcentaje de germinación, emergen- cia de plántulas e índice de velocidad de emergencia. A partir de estos resultados se concluye que la remoción del pericarpio en semillas de crambe, cultivar FMS Brilhante, aceleró la velo- cidad de germinación, pero, disminuyó su porcentaje final. La pre-imbibición en ácido giberélico (400, 500 e 600 mg.L -1 ) por 24 horas proporcionó incrementos en la germinación y en el vigor de las semillas de crambe con pericarpio.

The objective of this study was to evaluate the phenotypic stability and adaptability of 25 sweet sorghum cultivars of Embrapa Maize and Sorghum. The experiments were conducted in five Brazilian environments, three in the state of Minas Gerais, and the others in Sinop, Mato Grosso and Pelotas, Rio Grande do Sul. Fresh biomass yield (FBY), and total soluble solids (TSS) of the juice were evaluated in a randomized complete block design with three replications. Analysis of variance showed significant genotype by environment interaction for both traits. According to the Annicchiarico methodology analysis, genotypes CMSXS634, BRS506, and CMSXS646 were the most stable and adapted for FBY and TSS concomitantly; CMSXS634 being more adapted to favorable environments and CMSXS646 being more adapted to unfavorable environments. O objetivo do presente estudo foi avaliar a adaptabilidade e estabilidade fenotípica de 25 cultivares de sorgo sacarino da Embrapa Milho e Sorgo. Os experimentos foram conduzidos em cinco ambientes, três no Estado de Minas Gerais e os demais nas cidades de Sinop - MT e Pelotas - RS, no delineamento em blocos ao acaso, com três repetições. Foram avaliados a produção de biomassa fresca (PBF) e o teor de sólidos solúveis totais (SST) do caldo. Na análise de variância conjunta, a interação genótipos com ambientes foi significativa para os dois caracteres avaliados. Para análise da adaptabilidade e estabilidade, utilizou-se o método de Annicchiarico. Os genótipos CMSXS634, BRS506 e CMSXS646 foram os mais adaptados e estáveis para PBF e SST concomitantemente, sendo CMSXS634 mais adaptado a ambientes favoráveis e CMSXS646 a ambientes desfavoráveis.

Conselho Nacional de Desenvolvimento Científico e Tecnológico Anthracnose, rust, and angular leaf spot incited by Colletotrichum lindemuthianum, Uromyces appendiculatus and Pseudocercospora griseola, respectively, are important diseases causing serious damages to the common bean crop. The common bean breeding program of BIOAGRO/UFV developed a line with carioca type grains (Rudá "R") containing the following resistance genes: Co-4, Co-6 and Co-10 (anthracnose); Ur-ON (rust) and Phg-1 (angular leaf spot). To transfer those genes to a black bean background, a backcrossing program was conducted with the aid of molecular markers, by involving Rudá "R" (donor genitor) and cultivar Diamante Negro (recurrent genitor). By selfing 32 BC3F1 plants, 40 black grained lines were obtained that possessed combinations with at least three markers linked to those genes. The lines were evaluated for resistance to the different races of C. lindemuthianum, U. appendiculatus and P. griseola. Lines DNR14 and DNR16 were resistant to all evaluated races of C. lindemuthianum, except for race 2047. Lines DNR12, DNR31, DNR36 and DNR38 were resistant to two races of U. appendiculatus. Lines DNR3, DNR4, DNR5, DNR7, DNR8, DNR10, DNR12, DNR24, DNR30, DNR33 and DNR34 were resistant to all races of P. griseola tested. The yield potentials of all 40 lines were evaluated during the winter season of 2006 and the dry season of 2007. The yield potentials of all lines were statistically equal to or higher than those of Rudá R and Diamante Negro. To increase the gene pyramid in the black-type background BC3F2 plants Diamante Negro x Rudá "R") containing the genes Co-6, Co-10, Ur-ON and Phg-1 were crossed with the carioca line Rudá "R1" carrying the genes Co-42, Co-5, Co-6, Co-10, Ur-ON and Phg-1. From this crossing and selection with molecular markers, 35 F4 families with black grains and at least five resistance markers were obtained. F2 plants [BC3F2 (Diamante Negro x Rudá "R") x Rudá "R1"] containing the genes Co-42, Co-5, Co-6, and Phg-1 were crossed with plants of the F2:3 families containing the genes Ur-ON, Ur-5 and Ur-11 for transfering the Ur genes to the black bean pyramid. It was possible to obtain eight F3 families with at least five markers associated to resistance genes; however, two of them showed carioca type grains, whereas the grains of the other ones did not present the grain patterns acceptable for either the groups carioca or black. Plants [BC3F2 (Diamante Negro x Rudá "R") x Rudá "R1"] containing the genes Co-42, Co-5, Co-6, Co-10, Ur-ON and Phg-1 were crossed with the cultivar MAR 2 (Phg-MAR 2) and those with the genes Co-42, Co-5, Co-6, Co-10 and Ur-ON were crossed with the cultivar Cornell 49-242 (Phg-3). BC3F2 plants (Diamante Negro x Rudá "R") containing the genes Co-4, Co-6, Co-10, Ur-ON and Phg-1 were crossed with BC3F2 individuals (Rudá x BAT 332) harboring the Phg-62 gene. In the three crossings and at each generation, the plants obtained were selected with molecular markers linked to each gene involved into crossings and also with markers for the genes I and bc-3 which confer resistance to the Bean Common Mosaic Virus. From the first cross, 16 plants with at least eight genes were obtained, and nine out of the 16 plants generated black-colored seeds. From the second cross, 13 plants with eight or nine genes generating only black F3 seeds were obtained, but they were all shiny. From the third cross, ten F4 families with black grains and at least two resistance genes were obtained. To transfer resistance genes to red-grained beans, crossings and backcrossing cycles were conducted between the cv. Vermelhinho (recurrent genitor) and Rudá "R", as well as between cv. Ouro Vermelho (recurrent genitor) and Rudá "R1". In those crossings, selection were also based on molecular markers linked to the genes of interest and on the grain color pattern. For the crossing between cv. Vermelhinho and Rudá "R", BC2F3 19 families containing at least two resistance genes and red grains were obtained. In the other crossing, 29 BC2F3 families with red grains and at least four markers were selected. According to the results, the following conclusions were drawn: the selection assisted by molecular markers in the process for obtaining lines with several resistance genes is efficient; the molecular markers should be tightly linked to the resistance genes; and transferring the genes between cultivars from different grain groups is slow, and requires a high number of backcrossings for recovering the original grain type. Antracnose, ferrugem e mancha-angular, incitadas, respectivamente, por Colletotrichum lindemuthianum, Uromyces appendiculatus e Pseudocercospora griseola, são importantes doenças que causam sérios prejuízos à cultura do feijoeiro. O programa de melhoramento do feijoeiro do BIOAGRO/UFV desenvolveu uma linhagem com grãos carioca (Rudá R ) contendo os seguintes genes de resistência: Co-4, Co-6 e Co-10 (antracnose); Ur-ON (ferrugem) e Phg-1 (mancha-angular). Para transferir tais genes para feijão de grão preto, foi conduzido um programa de retrocruzamentos, auxiliado por marcadores moleculares, envolvendo Rudá R e o cv. Diamante Negro (genitor recorrente). A partir da autofecundação de 32 plantas RC3F1, foram obtidas 40 linhagens com grãos pretos que possuíam combinações de, no mínimo, três marcas ligadas aos genes mencionados. As linhagens foram avaliadas quanto à resistência a diferentes raças de C. lindemuthianum, U. appendiculatus e P. griseola. As linhagens DNR14 e DNR16 foram resistentes a todas as raças avaliadas de C. lindemuthianum, com exceção da raça 2047. As linhagens DNR12, DNR31, DNR36 e DNR38 foram resistentes às duas raças de U. appendiculatus avaliadas. As linhagens DNR3, DNR4, DNR5, DNR7, DNR8, DNR10, DNR12, DNR24, DNR30, DNR33 e DNR34 foram resistentes a todas raças de P. griseola avaliadas. O potencial produtivo das 40 linhagens também foi avaliado nas safras de inverno em 2006 e de seca em 2007. Todas as linhagens apresentaram rendimento estatisticamente igual ou superior a Rudá R e Diamante Negro. Para incrementar a pirâmide de genes no background preto, plantas RC3F2 (Diamante Negro x Rudá R ) contendo os genes Co-6, Co-10, Ur-ON e Phg-1 foram cruzadas com a isolinha carioca Rudá R1 , portadora dos genes Co-42, Co-5, Co-6, Co-10, Ur-ON e Phg-1. A partir deste cruzamento e seleção com marcadores moleculares, foram obtidas 35 famílias F4 com grãos pretos e com, no mínimo, cinco marcas de resistência. Plantas F2 [RC3F2 (Diamante Negro x Rudá R ) x Rudá R1 ], contendo os genes Co-42, Co-5, Co-6, e Phg-1, foram cruzadas com indivíduos de famílias F2:3, contendo os genes Ur-ON, Ur-5 e Ur-11, para transferência de genes Ur para a pirâmide. Foi possível obter oito famílias F3 com, no mínimo, cinco marcas associados a genes de resistência, porém, duas delas apresentaram grãos carioca e as demais, grãos fora dos padrões aceitáveis para os grupos carioca e preto. Plantas [RC3F2 (Diamante Negro x Rudá R ) x Rudá R1 ], contendo os genes Co-42, Co-5, Co-6, Co-10, Ur-ON e Phg-1 foram cruzadas com o cv. MAR 2 (Phg-MAR 2) e as que continham os genes Co-42, Co-5, Co-6, Co-10 e Ur-ON foram cruzadas com o cv. Cornell 49-242 (Phg-3). Plantas RC3F2 (Diamante Negro x Rudá R ) contendo os genes Co-4, Co-6, Co-10, Ur-ON e Phg-1, foram cruzados com indivíduos RC3F2 (Rudá x BAT 332), que possuíam o gene Phg-62. Nos três cruzamentos, a cada geração as plantas obtidas foram selecionadas com marcadores moleculares ligados a cada gene envolvido nos cruzamentos além dos marcadores para os genes I e bc-3. A partir do primeiro cruzamento foram obtidas 16 plantas com, no mínimo, oito genes, sendo que nove delas geraram sementes de cor preta. No segundo, obteve-se 13 plantas com oito ou nove genes que geraram somente sementes F3 pretas, mas com brilho. No terceiro, dez famílias F4 foram obtidas com, no mínimo, dois genes e todas com grãos pretos. Para transferir genes de resistência para feijões de grão vermelho, cruzamentos e ciclos de retrocruzamentos entre o cv. Vermelhinho (genitor recorrente) e Rudá R foram conduzidos, bem como entre Ouro Vermelho (genitor recorrente) e Rudá R1 . Nesses cruzamentos as seleções também foram realizadas por marcadores moleculares ligados aos genes envolvidos e no padrão de cor dos grãos. Para o cruzamento entre Vermelhinho e Rudá R foram obtidas 19 famílias RC2F3 contendo no mínimo dois genes e com grãos vermelhos. No outro cruzamento, 29 famílias RC2F3 de grãos vermelhos e com quatro marcas, no mínimo, foram selecionadas. Diante dos resultados podê-se concluir que a seleção assistida por marcadores moleculares no processo de obtenção de linhagens com vários genes de resistência é eficiente, que os marcadores moleculares ligados a genes de resistência devem ser altamente específicos para que possam auxiliar no processo de transferência de genes para outros backgrounds genéticos e que a transferência de genes entre cultivares de grupos de cor de grão diferentes é demorado, exigindo a realização de um maior número de retrocruzamentos para a recuperação do tipo de grão original.

Conselho Nacional de Desenvolvimento Científico e Tecnológico O cultivar de feijão preto Diamante Negro além da boa aceitação comercial, apresenta resistência ao crestamento-bacteriano-comum e ao mosaico comum. No Programa de Melhoramento do Feijoeiro do BIOAGRO/UFV, foi produzida uma isolinha de grãos tipo carioca (Rudá “R”) contendo simultaneamente genes de resistência à Colletotrichum lindemuthianum (genes Co-6 e Co-4), à Uromyces appendiculatus (genes Ur-?) e à Phaeoisariopsis griseola (gene Phg –1), com o auxílio de marcadores moleculares ligados a cada um desses genes. Os objetivos deste trabalho foram: caracterizar o cultivar Diamante Negro quanto à reação às principais raças de C. lindemuthianum (antracnose), U. appendiculatus (ferrugem) e P. griseola (mancha-angular) e também quanto ao seu fingerprint molecular por meio de marcadores do DNA, e transferir genes de resistência já piramidados na isolinha Rudá “R”, para esse cultivar. O Diamante Negro foi inoculado com 10 patótipos de C. lindemuthianum, 10 de U. appendiculatus e seis de P. griseola. No resultado da avaliação, o Diamante Negro mostrou-se suscetível a três patótipos de C. lindemuthianum (65, 81 e 89) e resistente, mas segregante, a quatro (55, 87, 95 e 342). Com relação a U. appendiculatus, comportou-se como suscetível a todos os patótipos. Com relação a P. griseola, foi suscetivel a quatro patótipos (31.17, 63.19, 63.23 e 63.55). Para sua caracterização molecular frente a outros cultivares do tipo preto e ao cultivar Rudá, pela técnica de RAPD, foram utilizados 78 primers, gerando 146 bandas polimórficas que permitiram o cálculo das distâncias genéticas e análise de agrupamento. A maior distância observada em relação ao Diamante Negro foi com o cultivar andino Preto 60 dias (26,79%), a menor com o Ouro Negro (6,42%) e o Rudá mostrou-se a uma distância de 28,11%. Três grupos foram formados: um contendo o Preto 60 dias (andino), um contendo o Rudá (mesoamericano-carioca) e um contendo os demais cultivares (mesoamericanos-pretos). Para a introgressão dos genes de resistência, cruzamentos entre Diamante Negro e o Rudá “R” foram realizados e as plantas F 1 foram retrocruzadas com o Diamante Negro gerando 394 plantas. Com inoculações seriadas com os três patógenos, foi possível selecionar 32 plantas resistentes às três doenças. O DNA destas 32 plantas foi amplificado com os marcadores SCAR Y20 830a (Co-4), SCAR H13 490a (Phg-1), SCAR AZ20 940a (Co-6) e SCAR F10 1050a e SCAR BA08 560a (Ur-?). Com o resultado desta amplificação foi possível selecionar 21 plantas que possuíam pelo menos quatro marcas, sendo que quatro destas plantas (75, 93, 141 e 270) apresentaram as cinco marcas. As distâncias genéticas relativas entre estas plantas RC 1 F 1 e o Diamante Negro variaram de 37 a 65%. Todas as 21 plantas RC 1 F 1 foram conduzidas para o segundo retrocruzamento, gerando 231 plantas RC 2 F 1 . A amplificação do DNA destas plantas RC 2 F 1 com os marcadores SCAR, permitiu selecionar 18 plantas com pelo menos quatro marcas. Seis destas (75.8, 93.8, 141.2, 141.4, 141.6 e 141.7) apresentaram as cinco marcas. As distâncias genéticas relativas entre as plantas selecionadas e o Diamante Negro foram de 32 a 48%. As 18 plantas selecionadas foram usadas para o terceiro retrocruzamento. O objetivo final deste trabalho é o de selecionar linhagens de grãos pretos com resistência à antracnose, ferrugem, mancha-angular, crestamento- bacteriano-comum e mosaico comum, com bom potencial produtivo. Diamante Negro, a black-seeded common bean cultivar, is not only outstanding because of its excellent commercial acceptability, but also because it is resistant to common bean leaf blight and to common bean mosaic virus. Using molecular marker assisted selection, the common bean breeding program of the Universidade Federal de Viçosa (BIOAGRO) developed an isoline with carioca type grains (Rudá “R”) containing genes for resistance to Colletotrichum lindemuthianum (genes Co-6 and Co-4), to Uromyces appendiculatus (genes Ur-?), and to Phaeoisariopsis griseola (gene Phg –1). The objectives of this study were: a) to characterize the cultivar Diamante Negro in relation to its reaction to the main C. lindemuthianum (anthracnose), U. appendiculatus (rust), and P. griseola (angular leaf spot) races; b) to determine its molecular fingerprint using DNA markers; and c) to transfer the resistance genes present in Rudá “R” to this cultivar. Diamante Negro was inoculated with 10 pathotypes of C. lindemuthianum, 10 of U. appendiculatus, and six of P. griseola. Diamante Negro was susceptible to three pathotypes of C. lindemuthianum (65, 81, and 89) and resistant, though segregant, to four other (55, 87, 95, and 342). The cultivar was susceptible to all pathotypes of U. appendiculatus and to four pathotypes of P. griseola (31.17, 63.19, 63.23, and 63.55). The genetic distances between Diamante Negro and xother black-seeded cultivars and cultivar Rudá were determined. Seventy- eight RAPD primers produced 146 polymorphic bands. Andean cultivar Preto 60 dias presented the greatest distance in relation to Diamante Negro (26.79%), Ouro Negro, the shortest distance (6.42%), and Rudá a distance of 28.11%. Based on the genetic distances, three groups were formed: one containing Preto 60 dias (andean), the other containing Rudá (“carioca-type”, mesoamerican) and the last one including all the other cultivars (black-seeded, mesoamerican). For the introgression of the resistance genes, the F 1 plants of the cross Diamante Negro x Rudá “R” were backcrossed with Diamante Negro, producing 394 plants. By serial inoculations with the three pathogens, 32 plants resistant to the three diseases were selected. The DNA of these 32 plants was amplified with the markers 1), and SCAR SCAR Y20 830a (Co-4), F10 1050a and SCAR SCAR AZ20 940a (Co-6), SCAR H13 490a (Phg- BA08 560a (Ur-?). Twenty-one plants were selected harboring at least four markers of the markers. Four of these plants presented all five markers. The relative genetic distances between these RC 1 F 1 plants and Diamante Negro varied from 37 to 65%. All 21 RC 1 F 1 plants were included in the second backcrossing, giving rise to 231 RC 2 F 1 plants. The DNA amplification of these plants with the SCAR markers led to the selection of 18 plants with at least four markers. Six among them presented the five markers. Relative genetic distances between the selected plants and Diamante Negro ranged between 32 and 48%. The 18 selected plants were used for a third backcross. The ultimate goal of this work is to select black-seeded lines with resistance to anthracnose, rust, angular lea spot, common leaf blight and common mosaic with a promising yield potential.

A cultivar de feijoeiro (Phaseolus vulgaris) Cornell 49-242, possuidora do gene de resistência Co-2 (Are), é uma das mais antigas fontes de resistência à antracnose, causada por Colletotrichum lindemuthianum. Visando a utilização desta fonte no programa de piramidação de genes em cultivares do tipo "carioca" do BIOAGRO/UFV, este trabalho teve como objetivos: (1) definir o padrão de herança da resistência da cultivar de feijoeiro Cornell 49-242 em cruzamentos com cultivares suscetíveis às raças 81 (Rudá) e 65 (Rudá e Ouro Negro) de C. lindemuthianum e (2) avaliar o marcador RAPD OPQ04(1440C) ligado ao gene Co-2 em populações F2 do cruzamento Rudá vs. Cornell 49-242. Os resultados indicaram que três genes dominantes, sendo dois de caráter complementar, controlam a resistência ao patótipo 81 de C. lindemuthianum, enquanto que um gene dominante e um recessivo controlam a resistência ao patótipo 65. O marcador OPQ04(1440C), previamente identificado como ligado ao gene Co-2 , pode ser usado, na prática, nesta população, para selecionar linhagens F2:3 contendo o gene Co-2. The cultivar Cornell 49-242 of common bean (Phaseolus vulgaris) harbors the Co-2 gene (Are) one of the oldest sources of resistance to anthracnose, caused by Colletotrichum lindemuthianum. Aiming to use this gene in the breeding program being conducted at the BIOAGRO/UFV, by pyramiding resistance genes in "carioca-type" cultivars, this work had the following objectives: (1) to determine the inheritance pattern of resistance of cultivar Cornell 49-242 in crosses with cultivars Rudá (susceptible to C. lindemuthianum races 81 and 65) and Ouro Negro (susceptible to race 65) and (2) to evaluate the RAPD marker OPQ04(1440C) linked to the Co-2 gene in F2 populations derived from the cross Rudá vs. Cornell 49-242. The results indicated the involvement of three independent dominant genes, two of which behave as complementary factors that control resistance to pathotype 81, and one dominant and one recessive genes which control resistance to pathotype 65. The marker OPQ04(1440C) previously identified as linked to Co-2 gene can be used to select F2:3 lines in these populations for the presence or absence of the Co-2 gene.

Eleven primers RAPD were used to estimate the genetic variability between 31 isolates of M. musicola collected from 'PrataAnã' and Nanica bananas that were cultivated in northern Minas Gerais, Brazil. A total o 83 fragments were amplified, of which 73 were polymorphic, corresponding to an average of 6.6 polymorphic fragments per primer. The genetic distances ranged from 0.06 to 0.56 and the average distance of 0.21. A dendrogram constructed based on the UPGMA clustering method revealed 8 and no correlation between molecular grouping and geographical origin was observed. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate the phenotypic stability and adaptability of 25 sweet sorghum cultivars of Embrapa Maize and Sorghum. The experiments were conducted in five Brazilian environments, three in the state of Minas Gerais, and the others in Sinop, Mato Grosso and Pelotas, Rio Grande do Sul. Fresh biomass yield (FBY), and total soluble solids (TSS) of the juice were evaluated in a randomized complete block design with three replications. Analysis of variance showed significant genotype by environment interaction for both traits. According to the Annicchiarico methodology analysis, genotypes CMSXS634, BRS506, and CMSXS646 were the most stable and adapted for FBY and TSS concomitantly; CMSXS634 being more adapted to favorable environments and CMSXS646 being more adapted to unfavorable environments.
