Resumo: Efficient strategies to manipulate the genetic variability are crucial to the success of breeding programs Coffea canephora. Combinations between divergent parents express greater heterosis effect, and the selection of matrices consider both genetic divergence and superior agronomic performance. The objective of this study was to quantify the genetic diversity of C. canephora accesses Active Germplasm Bank of Embrapa Rondônia, in order to identify plants of greater genetic diversity and higher yield potential for hybridization. For this, between 1100 accessions were pre-selected 89 plants for evaluation of major components in the production of processed coffee. For quantification of genetic diversity technique for principal components associated landmarks to gather the information of genetic divergence and agricultural performance in a single analysis was used. The selected accessions showed significant genetic variability for the major components of production, highlighting the values of average blend above 17, which indicates a favorable condition for performing controlled crosses for selection of plants for increased productivity and grain size.

Combinações entre genitores divergentes expressam maior efeito heterótico, devendo a seleção de matrizes considerar, simultaneamente, a divergência genética e o desempenho agronômico superior.Objetivou-se, neste trabalho, quantificar a diversidade genética de acessos de C. canephora do Banco Ativo de Germoplasma da Embrapa Rondônia, visando à identificação de plantas de maior divergência genética e maior potencial produtivo para hibridização. Para isso, entre 1100 acessos foram pré-selecionadas 89 plantas para avaliação dos principais componentes da produção de café beneficiado. Para a quantificação da diversidade genética foi utilizada a técnica de componentes principais, associada a pontos de referência para reunir as informações de divergência genética e de desempenho agrícola em uma única análise. Os acessos selecionados apresentaram expressiva variabilidade genética para os principais componentes de produção, com destaque para os valores de peneira média acima de 17, o que indica uma condição favorável para a realização de cruzamentos controlados visando à seleção de plantas de maior produtividade e tamanho de grãos.Editora UFLA2014-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/504Coffee Science - ISSN 1984-3909; Vol. 8 No. 4 (2013); 478-485Coffee Science; Vol. 8 Núm. 4 (2013); 478-485Coffee Science; v. 8 n. 4 (2013); 478-4851984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/504/pdf_66Copyright (c) 2014 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessRocha, Rodrigo BarrosSantos, Diogo VieiraRamalho, André RostandTeixeira, Alexsandro Lara2014-03-31T13:20:27Zoai:coffeescience.ufla.br:article/504Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:43.365727Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
