Resumo: The objective of this work was to verify the nine-hole system efficiency in the evaluation of common bean (Phaseolus vulgaris) carioca-type progenies for plant architecture. Ninety-seven progenies were evaluated in the F2:3 and F2:4 generations in an randomized block design, with 20 replicates, and nine plants per plot, in which the central plant was evaluated, and the eight neighbor ones were considered together as the control. The evaluated traits were: grain yield per plant, architecture and lodging. The joint selection index (Zij) for the three characters was obtained through the sum of the standardized values per plot. Data were submitted to the analysis of variance, and from the mean square expected values, the components of variance were estimated. It is possible to identify more upright plants using the nine-hole system, in segregating common bean populations. This system allows for high estimates of experimental accuracy and heritability.

Foram avaliadas 97 progênies nas gerações F2:3 e F2:4, em delineamento de blocos ao acaso, com 20 repetições e nove plantas por parcela, em que a planta central foi avaliada, e as oito vizinhas foram consideradas conjuntamente como controle. Avaliaram-se os caracteres: produção de grãos por planta, porte e acamamento. O índice de seleção conjunta, para as três características (Zij), foi obtido pelo somatório dos valores padronizados por parcela. Os dados foram submetidos à análise de variância e, a partir das esperanças dos quadrados médios, foram estimados os componentes de variância. É possível identificar plantas mais eretas em populações segregantes do feijoeiro, utilizando-se o sistema de nove covas. Este sistema possibilita a obtenção de elevadas estimativas de acurácia experimental e herdabilidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPEMIG, CNPqMendes, Flávia FerreiraRamalho, Magno Antônio PattoAbreu, Ângela de Fátima Barbosa2011-12-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/9706Pesquisa Agropecuaria Brasileira; v.46, n.9, set. 2011; 1029-1034Pesquisa Agropecuária Brasileira; v.46, n.9, set. 2011; 1029-10341678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/9706/6561https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9706/4950info:eu-repo/semantics/openAccess2014-06-10T18:42:08Zoai:ojs.seer.sct.embrapa.br:article/9706Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-10T18:42:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
