Progressos genéticos em progênies de café por diferentes critérios de seleção
In order to investigate the aspects related to the use of selection indexes in Coffea arabica breeding, analytical procedures were used: index based on the sum of ranks of Mulamba and Mock (ISR), index of desired gains of Pesek and Baker (DGI), classic index of Smith and Hazel (CI), base index of Williams (BI), and direct and indirect selection (DIS). Thirty-nine progenies were evaluated in the 4th generation by selfing after the 2nd backcross between “Catuai” and “Mundo Novo”. The evaluations were realized in coffee plants from 30 months old on, having the following characteristics: yield of eight harvests, classification for blend 16 and over, percentage of floating fruits, vegetative vigor and percentage of flat beans. The analytical procedures of selection indexes showed possibilities of applications in advanced generations of breeding being superior when compared with DIS. The DGI was not appropriate in the situation analyzed in this work. The selection based on CI and BI was the criteria that showed the best results in terms of gains in yield and grain size, and in the distribution of gains in the other characteristics.Objetivando-se investigar os aspectos relacionados à utilização de índices de seleção no melhoramento de café arábica, foram utilizados os procedimentos analíticos: índice com base em soma de postos de Mulamba and Mock (ISP), índice de ganhos desejados de Pesek and Baker (IGD), índice clássico de Smith e Hazel (IC), índice-base de Williams (IB) e a seleção direta e indireta (SDI). Foram avaliadas 39 progênies na 4ª geração por autofecundação, após o 2º retrocruzamento entre ‘Catuaí’ e ‘Mundo Novo’. As avaliações foram realizadas em cafeeiros a partir dos 30 meses de idade, compreendendo as seguintes características: produtividade de oito colheitas, classificação quanto à peneira 16 e acima, porcentagem de frutos granados, vigor vegetativo e porcentagem de grãos chatos. Os procedimentos analíticos dos índices de seleção apresentam possibilidades de aplicações em gerações avançadas de melhoramento sendo superiores em relação à SDI. O IGD não foi adequado na situação analisada no presente trabalho. A seleção com base nos IC e IB foi o critério que apresentou os melhores resultados em termos de ganhos em produtividade e tamanho de grãos e na distribuição de ganhos nas demais características

Partial map of Coffea arabica L. and recovery of the recurrent parent in backcross progenies
A partial map of Coffea arabica L. was constructed based on a backcross population and RAPD markers.From a total of 178 markers evaluated, only 134 that segregated 1:1 (P>0.05) were used to develop the map. Seventeenmarkers were not linked, while 117 formed 11 linkage groups, covering a genome distance of 803.2 cM. The maximumdistance between adjacent markers was 26.9 cM, and only seven intervals exceeded 20 cM. The markers were further used forassisted selection of the plants closest to the recurrent parent, to accelerate the introgression of rust resistance genes in thecoffee breeding program. Three BC1 plants resistant to coffee leaf rust and with high genetic similarity to Catuaí wereselected and integrated in the following backcross cycles
Paralympic judo : professional performance in sports initiation
Orientador: José Julio Gavião de AlmeidaDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Educação FísicaResumo: O judô é uma das modalidades inclusas nos jogos paralímpicos e vem mostrando grande crescimento no Brasil em resultados e em número de praticantes. No entanto, as atuais práticas de aprendizado e sua influência no envolvimento e permanência do praticante no esporte ainda são pouco abordadas na pesquisa científica. O objetivo desse estudo foi realizar um levantamento sobre a atuação profissional de treinadores de judô paralímpicos de diferentes países das Américas e Europa no processo de iniciação esportiva com crianças, jovens e adultos. Esta pesquisa de caráter quantitativa utilizou do método survey com escala likert de 5 pontos para mapear o tempo de experiência como treinador, formação acadêmica, atuação profissional e materiais utilizados por esses treinadores de referência. As questões sobre a atuação profissional foram divididas em dois grupos: tradicional e inovador. Essa investigação contou com a participação de 20 treinadores de judô paralímpico de 11 países das Américas (Brasil, Argentina, Colômbia, México, Chile, Honduras, Estados Unidos, Canada, Porto Rico) e Europa (Grã-Bretanha e França) que participaram dos Jogos Parapan Americanos de Jovens ¿ São Paulo 2017, American Judo Championships IBSA ¿ São Paulo 2017 e Gran Prix Internacional de Judô Paralímpico ¿ São Paulo 2017. Todos os treinadores possuem curso superior sendo em sua maioria em Educação Física ou similar 70% (14). Os materiais utilizados citados pelos treinadores foram: cordas (25%) bolas (23,3%), panos (11,6%), balões (10%), arcos (10%), pregadores (6,6%), cordas elásticas (5%), halteres (1,6%), cones (1,6%), faixas (1,6%), meias (1,6%) e mascaras (1,6%). A partir da análise estatista no programa SPSS, foi realizado o teste de Wilcoxon, mediana e moda, revelando diferença significante (p0.05) entre a formação acadêmica, tempo de experiência como treinador de judô e judô paralímpico com as respostas das duas categorias As questões com o maior percentual (75%+) de número 5 (extremamente) na escala likert entre os treinadores foram: a utilização do tato e comunicação verbal para auxiliar no ensino de alunos com deficiência visual; a importância de sempre buscar novas estratégias de ensino e a importância em manter a tradição do ensino do judô para os alunos com deficiência visual. Acreditamos que os resultados desta pesquisa tragam novas perspectivas, baseada em treinadores de referência da modalidade, aos futuros treinadores de judô paralímpico, possibilitando novas abordagens e práticas profissionaisAbstract: Judo is one of the sports included in the Paralympic Games and has increased significantly in Brazil with great positive results and in number of practitioners. However, the current learning practices and their influence on practitioner¿s engagement and permanence in the sport are still poorly addressed in scientific research. The objective of this research was to investigate the professional performance in coaching practices of Paralympic judo in different countries of the Americas and Europe, and how these practices influence sports initiation with children, youth and adults. This quantitative research used the survey method with 5 points Likert scale to map information such as: time of experience as coaches, formal academic training, professional performance and materials used by these reference coaches. The questions about professional performance were divided into two categories: traditional and innovator. This research was answered by 20 Paralympic judo coaches from 11 countries in the Americas (Brazil, Argentina, Colombia, Mexico, Chile, Honduras, United States, Canada, Puerto Rico) and Europe (Great Britain and France) during the American Youth Parapan Games - Sao Paulo 2017, American Judo Championships IBSA - São Paulo 2017 and the Gran Prix Internacional de Paralympic Judo - São Paulo 2017. All the coaches declared to possess undergraduate degrees, mostly in Physical Education or similar 70% (14). The materials used by the coaches were: ropes (25%), balls (23,3%), cloth pieces (11,6%), balloons (10%), hula hoops (10%), cloth fasteners (6,6%), therabands (5%), dumbbells (1,6%), cones (1,6%), bands(1,6%), socks (1,6%) and masks (1,6%). The analyses were conducted in the SPSS program. As results of the Wilcoxon test there were significant differences (p0.05) between academic degree, experience as a judo coach, and Paralympic judo with the answers of the two categories. Questions with the highest percentage (75% +) of score 5 (extremely) on Likert scale among the coaches were: the use of sensorial touch and verbal communication to assist the teaching process for students with visual impairment; the importance to always seek new teaching strategies and maintaining the judo teaching tradition for students with visual impairments. We believe that the result of this research brings a new perspective, based on the successful coaches of reference of this sport modality, to the future trainers of Paralympic judo, favoring new approaches and professional practicesMestradoAtividade Fisica AdaptadaMestre em Educação Física130903/2017-5CNP
Selection for later flowering in soybean (Glycine max L.Merrill) F2 populations cultivated under short day conditions
Several different selection strategies were used to estimate expected gain of days to flowering and other related characters in two F2 soybean (Glycine max (L.) Merrill) populations. The sample originated from crosses of lines whose seeds do not contain the three lipoxygenase isozymes with the commercially cultivated IAC-12. IAC-12 is a gene carrier for an extended juvenile period. This study was conducted during the winter of 1994 in Viçosa, Minas Gerais. The plants were grown under natural photoperiod. One population was grown in a heated greenhouse, and the other in the field under natural temperature conditions. Lower temperatures early in the field planting caused a delay in flowering. Delayed flowering caused a broader amplitude in all characters evaluated, and resulted in higher selection gains for the field-grown plants than for the greenhouse-grown plants. Direct selection for number of flowering days proved to be efficient for improving this character in both populations. Gains were also obtained for other characters. Interactions of temperature and photoperiod and temperature and genotypes affected soybean flowering time and produced alterations in other correlated agronomic characters, including productivity
Biodiversity conservation and sustainable development in the Amazon
The Amazon Forest is the most biodiverse region on earth and is central in the struggle to conserve biodiversity and control global warming. Biodiversity is not homogeneously distributed in the region, but concentrated within areas of endemism (AOE) that vary in size, degree of deforestation and human pressure. Unfortunately, these differences have not been used to guide governmental policies, land occupation and conservation. Instead, a violent occupation process started 40 years ago and marked by a frontier economy pattern is still under way. To change this course and truly promote a sustainable development mode in the Amazon region, we argue that an ambitious plan that includes completely halting illegal deforestation is needed. This plan should start by resolving land tenure issues and correctly assigning specific land uses. The three major land-use types in the region include protected areas (49% of the region), unprotected forests (39%) and altered lands (12-17%). Changing the current model of development implies shifting future uses and increasing support for these areas. This translates into three major goals: (1) adequately maintaining the integrity of the current protected areas, (2) protecting unprotected forests and (3) promoting higher productivity in deforested areas. The proportion of land-use types directed to each of these goals will depend on local socio-economic needs and conservation status, but must consider the AOE where it is present. Regional biodiversity corridors for each AOE should be planned and integrated into a large, Pan-Amazon biodiversity corridor to maintain the equilibrium of climatic and hydrological cycles. Politically, this corridor should aim at the integration of development and conservation plans beyond each country's boundary, minimizing impacts of infrastructure development and maximizing social and environmental benefits
