Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / O algodoeiro à a mais importante fibra tÃxtil do mundo. Entre os cultivares de algodÃo obtidos, aqueles com fibra naturalmente coloridas tem tido grande importÃncia como matÃria prima para a indÃstria tÃxtil, principalmente para atender demandas de tecidos ecolÃgicos e orgÃnicos. Nesse sentido, o presente trabalho foi conduzido com a finalidade de identificar genÃtipos de algodÃo de fibra colorida com boa produtividade e qualidade de fibra. Para tanto os objetivos especÃficos foram identificar genÃtipos contrastantes que possam ser utilizados no melhoramento do algodÃo colorido e tambÃm identificar que aÃÃes gÃnicas estÃo envolvidas no desempenho dos hÃbridos formados pelo cruzamento entre quatro cultivares de fibra colorida com seis cultivares tradicionais de fibra branca. Na primeira etapa do trabalho conduziu-se estudos de divergÃncia genÃtica nos genitores utilizados, por meio de tÃcnicas multivariadas, e na segunda etapa, foram estimados efeitos da capacidade geral de combinaÃÃo (CGC) e capacidade especÃfica de combinaÃÃo (CEC), identificando-se os tipos de aÃÃes gÃnicas envolvidas no controle das caracterÃsticas observadas por meio da metodologia REML/BLUP. Os dados foram coletados a partir da conduÃÃo de um experimento sob o delineamento de blocos casualizados com 24 tratamentos (14 hÃbridos e 10 genitores), no espaÃamento de 1,25 m entre linhas e 0,25 entre plantas e cinco plantas por parcela. Durante a colheita foram coletadas amostras de 20 capulhos de cada tratamento que foram utilizados para avaliaÃÃo de 12 caracterÃsticas tecnolÃgicas da fibra em HVI. As cultivares mais divergentes, envolvendo grupos distintos, foi entre a BRS Verde e BRS Buriti, seguidas da BRS Verde e BRS 293. As menores distÃncias foram obtidas entre as cultivares de fibra branca. Destaque para as cultivares BRS 286 e BRS 293. As caracterÃsticas CSP, %FIB, PAC e PAP foram mais importantes para a divergÃncia genÃtica entre os genitores. Os efeitos genÃticos aditivos tÃm maior importÃncia para o controle genÃtico das caracterÃsticas de produÃÃo e qualidade das fibras do algodÃo. / Cotton is the most important textile fiber in the world. Among all cotton cultivars released, those with naturally colored fiber has been of great importance as a raw material for the textile industry, mainly to meet demands for ecological and organic fabrics. In this sense, the aim of this study was identify genotypes of colored cotton fiber with good yield and fiber quality. The specific objectives were identify contrasting genotypes that can be used in breeding of colored cotton and also identify gene actions that are involved in the performance of the hybrids formed by crossing between four cultivars of colored fiber with six traditional cultivars of white fiber. In the first stage of the research it was conducted studies over genetic diversity in the parents used by univariate and multivariate techniques, and in the second step, we estimated effects of general combining ability ( GCA) and specific combining ability (SCA ), identifying the types of gene actions involved in the control of the observed features, using the methodology REML/BLUP. The statistical design used in the experimental data was randomized block with 24 treatments (14 hybrids and 10 parents), spaced 1,25 m between rows and 0,25 between plants and five plants per plot. They were collected samples from 20 bolls from each treatment used to evaluate 12 technological characteristics of the fiber in HVI. The most divergent cultivars, involving different groups, was between the BRS Verde and BRS Buriti, followed by BRS 293 and BRS. Smaller distances were obtained between cultivars of white fiber. Highlight for BRS 286 and BRS 293 cultivar. The features CSP,% FIB, PAC and PAP were more important for the genetic divergence between the parents. Additive genetic effects are more important for the genetic control of the characteristics of production and quality of cotton fibers.

Barrier trees are a convenient way of representing the structure of complex combinatorial landscapes over graphs. Here we generalize the concept of barrier trees to landscapes defined over general multi-parent search operators based on a suitable notion of topological connectedness that depends explicitly on the search operator. We show that in the case of recombination spaces, path-connectedness coincides with connectedness as defined by the mutation operator alone. In contrast, topological connectedness is more general and depends on the details of the recombination operators as well. Barrier trees can be meaningfully defined for both concepts of connectedness.

This diploma thesis is focused on topic of genetically modified organisms and their use in the practical sectors of human life. Theoretical part of the thesis defines general terms GMO, plasmid, genetic engineering, biotechnology. It also records historical milestones relating to the problematic, deals with individual techniques of genetic engineering and briefly states legislative procedures in context of dealing with GMO. It gives examples of transgenic organisms and summarizes advantages and disadvantages of their use.Practical part of the thesis contains educational program called "Genetically modified organisms", which was conceived by the author and includes a draft of a lesson inclusive of teaching materials - powerpoint presentations, worksheets, interactive worksheets, auxiliary text for teacher and written preparation. Research part deals with high school students change of view about using GMOs after completing the educational program. Due to analysis was proven that most of the attitudes and knowledge about GMO was changed after completing the educational program (for example in issues of willingness to consume GM food and animal products, perception of advantages and disadvantages etc.) Data was still unchanged in questions which cannot be affected by the program (control of food packaging or...
