Resumo: The cupuaçuzeiro (Theobroma grandiflorum), species native from the Amazon region, has been domesticated presenting a broad genetic variability, and thus favorable conditions for establishing of strategies to breeding and genetic conservation. The aim of this work was to evaluate 36 half-sib progenies of Theobroma grandiflorum obtained from a stratified mass selection in farmers areas based on primary components of yield. The experiment for selection of elite progenies was set up in a randomized complete block design with three replications and four plants per plot. The fruit traits (length and width, in cm) and components of production (average weight of fruit/plant; average weight of pulp with seeds/plant and average weight of pulp/plant, in g) were evaluated. The data were analyzed through the methodology of REML/BLUP using the Selegen software. Analysis of grouping was performed using the matrix of genetic euclidean distances and Mahalanobis. The experimental population allowed the selection of superior parents for formation of base population to be used in the genetic improvement of cupuaçu. Among the 36 analyzed lineages only the genotypes 9, 10 and 18 showed genetic divergence and they can be recommended with some lineage of group 1 that demonstrates agronomic superiority to form base population of experimental clones with high genetic dissimilarity.doi: 10.4336/2011.pfb.31.66.123

O objetivo foi avaliar geneticamente 36 progênies de meios-irmãos de cupuaçu oriundos de seleção massal estratificada em áreas de produtores, com base nos componentes primários da produtividade. O experimento para seleção das progênies superiores foi instalado no delineamento aleatorizado em blocos, com quatro plantas por parcela e três repetições. Foram consideradas as variáveis de caracterização do fruto (comprimento e largura, ambos em centímetro) e componentes de produção avaliados em grama (peso médio de fruto por planta, peso médio de polpa com sementes por planta e peso médio de polpa por planta). Os dados foram analisados através da metodologia REML/BLUP com o emprego do software Selegen. Para realizar o agrupamento, utilizaram-se matrizes de distâncias euclidianas genéticas e de Mahalanobis. A população experimental possibilitou a seleção de parentais superiores para formação de população base para o melhoramento genético do cupuaçu. Das 36 progênies analisadas, apenas as progênies 9, 10 e 18 mostraram divergência genética, podendo ser recomendadas juntamente com alguma progênie do grupo 1 que mostrar superioridade agronômica para formar população base de clones experimentais com alta dissimilaridade genética.doi: 10.4336/2011.pfb.31.66.123Embrapa Florestas2011-02-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/54Pesquisa Florestal Brasileira; v. 31 n. 66 (2011): abr./jun.; 123Pesquisa Florestal Brasileira; Vol. 31 No. 66 (2011): abr./jun.; 1231983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/54/212Cabral Maia, Maria ClideanaResende, Marcos Deon Vilela deOliveira, Luís Cláudio deAlves, Rafael MoisésSilva Filho, João Luis daRocha, Maurisrael de MouraCavalcante, José Jaime VasconcelosRoncatto, Givanildoinfo:eu-repo/semantics/openAccess2017-04-28T13:06:42Zoai:pfb.cnpf.embrapa.br/pfb:article/54Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T13:06:42Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
