Resumo: The objective of this work was to estimate the coefficients of repeatability in diploid banana hybrids, and predict the number of required measurements for main quantitative traits. The evaluated hybrids were: 042079‑06, TH03‑01, 089087‑01, 003023‑03, 013018‑01, 001016‑01, 086094‑20, 013004‑06, and 091079‑03. Twelve agronomic traits were measured in three cycles. For the repeatability coefficient estimate, the following analyses were performed: analysis of variance, principal components from the matrix of phenotypic variance and covariance analysis, and the correlation and structural analyses. For each trait, the minimum number of measurements to predict the actual value of the hybrids was determined. Genetic variability was observed among genotypes. Repeatability estimates were high, showing the regularity of accessions. One to five measurements are needed to predict the actual value of production characters. Methods based on principal component analysis are more efficient to estimate the coefficient of repeatability.

Os híbridos avaliados foram 042079‑06, TH03‑01, 089087‑01, 003023‑03, 013018‑01, 001016‑01, 086094‑20, 013004‑06 e 091079‑03. Em três ciclos, mediram-se doze características agronômicas. Para a estimativa dos coeficientes de repetibilidade foram utilizadas as análises de variância, de componentes principais a partir das matrizes de variância e covariância fenotípica, de correlação e análise estrutural. Determinou-se para cada característica o número mínimo de medições, para predizer o valor real dos híbridos. Observou-se variabilidade genética entre os genótipos. As estimativas de repetibilidade foram elevadas, o que mostra a regularidade dos acessos. Para predizer o valor real dos caracteres de produção são necessárias de uma a cinco medições. Os métodos baseados em análise multivariada de componentes principais são os mais eficientes para estimar os coeficientes de repetibilidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapa e CNPqLessa, Lauro SaraivaLedo, Carlos Alberto da SilvaAmorim, Edson PeritoSilva, Sebastião de Oliveira e2014-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/18533Pesquisa Agropecuaria Brasileira; v.49, n.2, fev. 2014; 109-117Pesquisa Agropecuária Brasileira; v.49, n.2, fev. 2014; 109-1171678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/18533/12585https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/18533/10980info:eu-repo/semantics/openAccess2014-05-09T18:35:52Zoai:ojs.seer.sct.embrapa.br:article/18533Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-09T18:35:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
