Resumo: Among the plants with potential ornamental, are the pepper plants belonging to the genus Capsicum and the family Solanaceae. Pepper ornamental potted have stood out in the ornamental market due to their characteristics aesthetic that include, among other attributes, the coloring of the fruits and leaves and harmony with the pot. The great diversity in this genus has allowed its use in breeding programs. The improvement of ornamental peppers is based mainly on the hybridization, generating segregant populations with the advancement of generations segregating it is possible to select the best lines of pepper plants with desirable characteristics for ornamental. The objective of this study was to evaluate the genetic diversity among and within the F4 populations of pepper plants, selecting families and promising genotypes for ornamental peppers. The experiment was carried out in a greenhouse at the Laboratory of Plant Biotechnology at the Center of Agricultural Sciences at the Federal University of Paraíba (CCA-UFPB). Were used ten families and four attestant additional of peppers for characterization morphoagronomic based on qualitative and quantitative descriptors. The experimental design was entirely randomized. The experimental unit consisted of one plant per pot. In the first chapter we used 16 quantitative descriptors of plant and fruit, the data were submitted to analysis of multivariate variance, the relative importance was determined by the Singh method, analysis of canonical variables and the Scott-Knot test. In the second chapter qualitative and quantitative and mixed descriptors were used. To quantify the relative contribution of traits to genetic divergence, the Singh criterion was used. Then, the Tocher grouping method was used based on the generalized Mahalanobis distance in the quantitative variables. In the qualitative variables, the Gower distance was used and later a mixed analysis was performed with the qualitative and quantitative data. In addition, non-metric multidimensional scaling was applied. All analyzes were performed with R version 3.0.3 software. In the first chapter by the Singh method it was determined that seven of the sixteen characteristics contributed with 62.70% of the genetic divergence. In the analysis of canonical variables, the first two canonical variables explained 68.05% of the families' discrimination and through the Scott-Knott test the families were grouped into 8 groups. The families that presented the desirable characteristics for ornamental pots were 17.18, 30.16, 30.22, 17.15 and 55.45. In the second chapter the genotypes were evaluated within each family and found that there is genetic diversity within the families analyzed, being possible to practice selection. The family 47.26 was the only one that did not present genotypes with ornamental size to be cultivated in smaller pots, since their plants presented high size.

As pimenteiras ornamentais cultivadas em vaso têm se destacado no mercado de ornamentais por suas características estéticas que envolvem, entre outros atributos, a coloração dos frutos e das folhas e harmonia com o vaso. A grande diversidade existente neste gênero tem permitido seu uso em programas de melhoramento genético. O melhoramento de pimenteiras ornamentais baseia-se principalmente, na hibridação, gerando populações segregantes Com o avanço de gerações segregantes é possível selecionar as melhores linhagens de pimenteiras com características desejáveis para ornamentais. Dessa forma objetivou-se avaliar a diversidade genética entre e dentro de populações F4 de pimenteiras, selecionando famílias e genótipos promissores para fins ornamentais. O experimento foi desenvolvido em casa de vegetação no Laboratório de Biotecnologia Vegetal no Centro de Ciências Agrárias na Universidade Federal da Paraíba (CCA-UFPB). Foram utilizadas 10 famílias e 4 testemunhas adicionais de pimenteiras para caracterização morfoagronômica com base em descritores qualitativos e quantitativos. O delineamento experimental empregado foi inteiramente casualizado. A unidade experimental foi constituída de uma planta por vaso. No primeiro capítulo foram usados 16 descritores quantitativos de planta e fruto, os dados foram submetidos a análise de variância multivariada, a importância relativa foi determinada pelo método de Singh, análise de variáveis canônicas e o teste de Scott-Knot. No Segundo capítulo foram utilizados descritores qualitativos e quantitativos e mistos. Para quantificar a contribuição relativa das características para a divergência genética foi utilizado o critério de Singh. Em seguida utilizou-se o método de agrupamento de Tocher com base na distância generalizada de Mahalanobis nas variáveis quantitativas. Nas variáveis qualitativas utilizou-se a distância de Gower e posteriormente foi realizada uma análise mista com os dados qualitativos e quantitativos. Além disso, foi aplicado o escalonamento multidimensional não métrico. Todas as análises foram realizadas com o software R versão 3.0.3. No primeiro capítulo pelo método de Singh determinou-se que sete das dezesseis características contribuíram com 62,70% da divergência genética. Na análise de variáveis canônicas, as duas primeiras variáveis canônicas explicaram 68,05% da discriminação das famílias e através do teste de Scott-Knott as famílias foram agrupadas em 8 grupos. As famílias que apresentaram as características desejáveis para ornamentais de vaso foram 17.18, 30.16, 30.22, 17,15 e 55.45. No segundo capítulo foram avaliados os genótipos dentro de cada família e constatou que há diversidade genética dentro das famílias analisadas, sendo possível praticar seleção. A família 47.26 foi à única que não apresentou genótipos com porte para ornamental para serem cultivadas em vaso menores, visto que suas plantas apresentavam porte alto.Universidade Federal da ParaíbaBrasilCiências Fundametais e SociaisPrograma de Pós-Graduação em AgronomiaUFPBRêgo, Elizanilda Ramalho dohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4795039Y6Rêgo, Mailson Monteiro dohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4795039T5Costa, Maria do Perpetuo Socorro Damasceno2019-05-20T11:25:09Z2019-02-272019-05-20T11:25:09Z2018-08-14info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesishttps://repositorio.ufpb.br/jspui/handle/123456789/14339porAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da UFPBinstname:Universidade Federal da Paraíba (UFPB)instacron:UFPB2019-05-21T06:04:35Zoai:repositorio.ufpb.br:123456789/14339Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufpb.br/PUBhttp://tede.biblioteca.ufpb.br:8080/oai/requestdiretoria@ufpb.br|| diretoria@ufpb.bropendoar:2019-05-21T06:04:35Biblioteca Digital de Teses e Dissertações da UFPB - Universidade Federal da Paraíba (UFPB)false
